This page will change as we update and add more content.&lt;br /&gt;
&lt;br /&gt;
When using slicing software such as Prusa Slicer to slice 3d models, there are several slicing settings that can be changed to adjust the final print. This might be reducing the print time, increasing the detail of the finished print, or changing the density of the part.&lt;br /&gt;
&lt;br /&gt;
'''''WARNING: Here be dragons. A basic understanding of 3d printing is heavily recommended past this point. You have been warned.'''''&lt;br /&gt;
&lt;br /&gt;
=Layer Height=&lt;br /&gt;
This is the setting you are most likely to change. Available layer heights for our machines (Except Turing, see below) are 0.1mm, 0.15mm, 0.2mm, and 0.25mm.&lt;br /&gt;
&lt;br /&gt;
Layer height dictates how thick each of the layer slices are. This drastically changes print time; a print with a layer height of 0.2mm will print twice as fast as one at 0.1mm, for example. To provide further control, Prusa Slicer offers Speed and Quality presets for every layer height.&lt;br /&gt;
&lt;br /&gt;
Our fastest machine, Turing, has a slightly different range: 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, and 0.4mm. This is due to Turing having an 0.6mm diameter hardened steel nozzle, instead of the default 0.4mm one. This lets us print thicker layers faster, but at the cost of quality. The hardened steel nozzle also allows us to print abrasive materials that would otherwise damage a machine, such as wood- and metal-infused filaments.&lt;br /&gt;

&lt;div&gt;'''Laser Cutter'''&lt;br /&gt;
&lt;br /&gt;
G139L&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;
Safely&lt;br /&gt;
&lt;br /&gt;
efficiently &lt;br /&gt;
&lt;br /&gt;
and for many years to come.&lt;br /&gt;
&lt;br /&gt;

     cutting area - 1300mm X 900mm&lt;br /&gt;

As we experiment with more materials this table will be updated to reflect the optimal settings. If a material is not listed here, always check with a team member before proceeding. If the team okays it, a good starting point for settings can be found on [https://www.noisebridge.net/wiki/Old_100W_Laser_Cutter_Settings_for_Known_Good_Materials this site].&lt;br /&gt;

=Approved Materials=&lt;br /&gt;
&lt;br /&gt;
All materials in this list have been tested with the Tinkd Makerspace G139L by one of our volunteers.&lt;br /&gt;
any questions feel free to ask.&lt;br /&gt;
&lt;br /&gt;
==list==&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
3mm-10mm tested successfully&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm pig skin leather tested&lt;br /&gt;
3mm pig skin tested&lt;br /&gt;
2mm unknown vege tan tested&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
up to 8mm successfully cut through(capable of cutting up to 20mm)&lt;br /&gt;
&lt;br /&gt;
===MDF===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
3mm successfully cut, need to attempt thicker materials&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm corflute tested, engraving must be on low power(less than 20%)&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
Engraving tested only&lt;br /&gt;
Low power engraving&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
20mm thickness cut successfully&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
Vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Leather#Tanning_methods Leather]&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Plywood Plywood]&lt;br /&gt;
&lt;br /&gt;
===MDF===&lt;br /&gt;
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board.&lt;br /&gt;
&lt;br /&gt;
Laser cutting MDF has an interesting side effect of sealing the edge, rather than burning it. This means the finish is much tidier, if you can live with the brown color.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Medium-density_fibreboard MDF]&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Corrugated_plastic Corflute]&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thin shell of plastic and a gyroid or honeycomb interior, although you can change [[Slicer settings|slicer settings]] to make it work better.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Polylactic_acid#Applications PLA ]&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
&lt;br /&gt;
=Unsafe Materials=&lt;br /&gt;
&lt;br /&gt;
Unsafe Material for Laser Cutter&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;

! scope=&amp;quot;col&amp;quot; |Material&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; |Danger&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; |Cause/consequence&lt;br /&gt;
|-&lt;br /&gt;
|'''PVC (Poly VinylChloride) /vinyl/pleather/artificial leather'''&lt;br /&gt;
|Emits pure chlorine gas when cut!&lt;br /&gt;
|''Don’t ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.''&lt;br /&gt;
|-&lt;br /&gt;
|'''ABS'''&lt;br /&gt;
|Emits cyanide gas and tends to melt&lt;br /&gt;
|ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt).&lt;br /&gt;
|-&lt;br /&gt;
|'''Thick(&amp;gt;1mm) Polycarbonate/lexan'''&lt;br /&gt;
|Cut very poorly, discolor,catch fire&lt;br /&gt;
|''Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting.''&lt;br /&gt;
|-&lt;br /&gt;
|'''HDPE/milk bottle plastic'''&lt;br /&gt;
|Catches fire and melts&lt;br /&gt;
|It melts. It gets gooey. Don’t use it.&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyStyrene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|''It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!''&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyPropylene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles.&lt;br /&gt;
|-&lt;br /&gt;
|'''Tempered Glass'''&lt;br /&gt;
|Shatters into a million pieces&lt;br /&gt;
|Can't cut or engrave - This creates extra stress on the glass and ''it will explode if you move it even slightly.''&lt;br /&gt;
|-&lt;br /&gt;
|'''Fiberglass'''&lt;br /&gt;
|Emits Fumes&lt;br /&gt;
|'' 	It’s a mix of two materials that cant’ be cut. Glass (etch, no cut) and epoxy resin (fumes)''&lt;br /&gt;
|-&lt;br /&gt;
|'''Coated Carbon Fiber'''&lt;br /&gt;
|Emits Noxious Fumes&lt;br /&gt;

=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;
Safely&lt;br /&gt;
&lt;br /&gt;
efficiently &lt;br /&gt;
&lt;br /&gt;
and for many years to come.&lt;br /&gt;

=Approved Materials=&lt;br /&gt;
&lt;br /&gt;
All materials in this list have been tested with the Tinkd Makerspace G139L by one of our volunteers.&lt;br /&gt;
any questions feel free to ask.&lt;br /&gt;
&lt;br /&gt;
==list==&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
3mm-10mm tested successfully&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm pig skin leather tested&lt;br /&gt;
3mm pig skin tested&lt;br /&gt;
2mm unknown vege tan tested&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
up to 8mm successfully cut through(capable of cutting up to 20mm)&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm corflute tested, engraving must be on low power(less than 20%)&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
Engraving tested only&lt;br /&gt;
Low power engraving&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
20mm thickness cut successfully&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Leather#Tanning_methods Leather]&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Plywood Plywood]&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Corrugated_plastic Corflute]&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thin shell of plastic and a gyroid or honeycomb interior, although you can change [[Slicer settings|slicer settings]] to make it work better.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Polylactic_acid#Applications PLA ]&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
&lt;br /&gt;
=Unsafe Materials=&lt;br /&gt;
&lt;br /&gt;
Unsafe Material for Laser Cutter&lt;br /&gt;
&lt;br /&gt;

! scope=&amp;quot;col&amp;quot; |Material&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; |Danger&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; |Cause/consequence&lt;br /&gt;
|-&lt;br /&gt;
|'''PVC (Poly VinylChloride) /vinyl/pleather/artificial leather'''&lt;br /&gt;
|Emits pure chlorine gas when cut!&lt;br /&gt;
|''Don’t ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.''&lt;br /&gt;
|-&lt;br /&gt;
|'''ABS'''&lt;br /&gt;
|Emits cyanide gas and tends to melt&lt;br /&gt;
|ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt).&lt;br /&gt;
|-&lt;br /&gt;
|'''Thick(&amp;gt;1mm) Polycarbonate/lexan'''&lt;br /&gt;
|Cut very poorly, discolor,catch fire&lt;br /&gt;
|''Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting.''&lt;br /&gt;
|-&lt;br /&gt;
|'''HDPE/milk bottle plastic'''&lt;br /&gt;
|Catches fire and melts&lt;br /&gt;
|It melts. It gets gooey. Don’t use it.&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyStyrene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|''It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!''&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyPropylene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles.&lt;br /&gt;
|-&lt;br /&gt;
|'''Tempered Glass'''&lt;br /&gt;
|Shatters into a million pieces&lt;br /&gt;
|Can't cut or engrave - This creates extra stress on the glass and ''it will explode if you move it even slightly.''&lt;br /&gt;
|-&lt;br /&gt;
|'''Fiberglass'''&lt;br /&gt;
|Emits Fumes&lt;br /&gt;
|'' 	It’s a mix of two materials that cant’ be cut. Glass (etch, no cut) and epoxy resin (fumes)''&lt;br /&gt;
|-&lt;br /&gt;
|'''Coated Carbon Fiber'''&lt;br /&gt;
|Emits Noxious Fumes&lt;br /&gt;

'''PrusaSlicer''' &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
To manipulate models/STL files and create Gcode file(3d printable file)&lt;br /&gt;
&lt;br /&gt;
'''Tinkercad''' &lt;br /&gt;
&lt;br /&gt;
used to create simple 3d models for printing, can also be used to modify existing models.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=important terms=&lt;br /&gt;
&lt;br /&gt;
'''STL, OBJ, and Gcode files'''&lt;br /&gt;
&lt;br /&gt;
There are 3 types of files you will be using the majority of time when it comes to 3D printing: either an .STL or .OBJ file, and a .gcode file. In simple terms, the stl and obj files are ways of storing an object in a 3 dimensional form digitally. The G-code file is a series of instructions telling the 3D printer how to turn that digital object into a physical item. For a deeper dive into G-code, see the wiki page on [[Editing gcode files]].&lt;br /&gt;
&lt;br /&gt;
''.STL file:'' &lt;br /&gt;
&lt;br /&gt;
An STL file, or Standard Triangle Language, is a file format allowing for a detailed 3 dimensional model to be created, in detail, using triangles. If you want to know more see the Wikipedia entry: [https://en.wikipedia.org/wiki/STL_(file_format) STL Files].&lt;br /&gt;
&lt;br /&gt;
Many of the models hosted on Thingiverse and similar websites provide their models as stl files. An stl file is easily recognizable for all of the Slicer programs we use at Tinkd to import and use.&lt;br /&gt;
&lt;br /&gt;
An STL file will look something like this:&lt;br /&gt;
&lt;br /&gt;
[[File:Stl file format.PNG]]&lt;br /&gt;
&lt;br /&gt;
You can see it is called a &amp;quot;3d object.&amp;quot; This file can be moved, copy/pasted, and renamed like any other type of file.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
''.OBJ file:''&lt;br /&gt;
&lt;br /&gt;
An OBJ or Object file is very similar to an STL file except it was initially designed for animation, but is now used by a variety of programs. The primary difference between the two is that an OBJ file contains material properties. More information can be found here: [https://en.wikipedia.org/wiki/Wavefront_.obj_file wavefront obj file].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
''G-code File''&lt;br /&gt;
&lt;br /&gt;
G-code is a popular programming language used in CNC manufacturing. In terms of 3D printing the G-code file is what tells the 3D printer where to move in order to create the object you want. to learn more about G-code see here [https://en.wikipedia.org/wiki/G-code G-code]. To learn about editing existing G-Code&lt;br /&gt;
Primarily you will be using a Slicer to create the Gcode for our Printers.&lt;br /&gt;
&lt;br /&gt;
''Slicer''&lt;br /&gt;
&lt;br /&gt;
A slicer is a computer program that takes a 3D object, like that represented in an STL file, and converts it into the movements needed by a machine, like our Prusa printers, to create that object physically. Our workstations have several Slicer programs that are available though the primary one we use is called Prusa Slicer. &lt;br /&gt;
&lt;br /&gt;
'''Thingiverse'''&lt;br /&gt;
&lt;br /&gt;
Thingiverse is a website dedicated to sharing 3d models, STL files and projects that anyone can contribute to. &lt;br /&gt;
&lt;br /&gt;
Why we like Thingiverse is:&lt;br /&gt;
*It's Free&lt;br /&gt;
*Huge variety in projects listed&lt;br /&gt;
*great community support&lt;br /&gt;
*It's open source&lt;br /&gt;

&lt;div&gt;'''Laser Cutter'''&lt;br /&gt;
&lt;br /&gt;
G139L&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;
Safely&lt;br /&gt;
&lt;br /&gt;
efficiently &lt;br /&gt;
&lt;br /&gt;
and for many years to come.&lt;br /&gt;

&lt;br /&gt;
All materials in this list have been tested with the Tinkd Makerspace G139L by one of our volunteers.&lt;br /&gt;
any questions feel free to ask.&lt;br /&gt;
&lt;br /&gt;
==list==&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
3mm-10mm tested successfully&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm pig skin leather tested&lt;br /&gt;
3mm pig skin tested&lt;br /&gt;
2mm unknown vege tan tested&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
up to 8mm successfully cut through(capable of cutting up to 20mm)&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm corflute tested, engraving must be on low power(less than 20%)&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
Engraving tested only&lt;br /&gt;
Low power engraving&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
20mm thickness cut successfully&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Leather#Tanning_methods Leather]&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Plywood Plywood]&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Corrugated_plastic Corflute]&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thin shell of plastic and a gyroid or honeycomb interior, although you can change [[Slicer settings|slicer settings]] to make it work better.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Polylactic_acid#Applications PLA ]&lt;br /&gt;

! scope=&amp;quot;col&amp;quot; |Danger&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; |Cause/consequence&lt;br /&gt;
|-&lt;br /&gt;
|'''PVC (Poly VinylChloride) /vinyl/pleather/artificial leather'''&lt;br /&gt;
|Emits pure chlorine gas when cut!&lt;br /&gt;
|''Don’t ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.''&lt;br /&gt;
|-&lt;br /&gt;
|'''ABS'''&lt;br /&gt;
|Emits cyanide gas and tends to melt&lt;br /&gt;
|ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt).&lt;br /&gt;
|-&lt;br /&gt;
|'''Thick(&amp;gt;1mm) Polycarbonate/lexan'''&lt;br /&gt;
|Cut very poorly, discolor,catch fire&lt;br /&gt;
|''Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting.''&lt;br /&gt;
|-&lt;br /&gt;
|'''HDPE/milk bottle plastic'''&lt;br /&gt;
|Catches fire and melts&lt;br /&gt;
|It melts. It gets gooey. Don’t use it.&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyStyrene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|''It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!''&lt;br /&gt;
|-&lt;br /&gt;
|'''PolyPropylene Foam'''&lt;br /&gt;
|Catches Fire&lt;br /&gt;
|Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles.&lt;br /&gt;
|-&lt;br /&gt;
|'''Tempered Glass'''&lt;br /&gt;
|Shatters into a million pieces&lt;br /&gt;
|Can't cut or engrave - This creates extra stress on the glass and ''it will explode if you move it even slightly.''&lt;br /&gt;
|-&lt;br /&gt;
|'''Fiberglass'''&lt;br /&gt;
|Emits Fumes&lt;br /&gt;
|'' 	It’s a mix of two materials that cant’ be cut. Glass (etch, no cut) and epoxy resin (fumes)''&lt;br /&gt;
|-&lt;br /&gt;
|'''Coated Carbon Fiber'''&lt;br /&gt;
|Emits Noxious Fumes&lt;br /&gt;

PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;

|-&lt;br /&gt;
|'''ABS'''&lt;br /&gt;
|Emits cyanide gas and tends to melt&lt;br /&gt;
|ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt).&lt;br /&gt;

|Cut very poorly, discolor,catch fire&lt;br /&gt;
|''Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation!

&lt;div&gt;'''Laser Cutter'''&lt;br /&gt;
&lt;br /&gt;
G139L&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;
Safely&lt;br /&gt;
&lt;br /&gt;
efficiently &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
All materials in this list have been tested with the Tinkd Makerspace G139L by one of our volunteers.&lt;br /&gt;
any questions feel free to ask.&lt;br /&gt;
&lt;br /&gt;
==list==&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
3mm-10mm tested successfully&lt;br /&gt;
&lt;br /&gt;

Cutting and engraving tested&lt;br /&gt;
up to 8mm successfully cut through(capable of cutting up to 20mm)&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm corflute tested, engraving must be on low power(less than 20%)&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
Engraving tested only&lt;br /&gt;
Low power engraving&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
20mm thickness cut successfully&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Leather#Tanning_methods Leather]&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Plywood Plywood]&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Corrugated_plastic Corflute]&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;

&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;

&lt;br /&gt;
G139L&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
All materials in this list have been tested with the Tinkd Makerspace G139L by one of our volunteers.&lt;br /&gt;
any questions feel free to ask.&lt;br /&gt;
&lt;br /&gt;
==list==&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;

up to 8mm successfully cut through(capable of cutting up to 20mm)&lt;br /&gt;
&lt;br /&gt;
===corflute===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
4mm corflute tested, engraving must be on low power(less than 20%)&lt;br /&gt;
&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;

Low power engraving&lt;br /&gt;
&lt;br /&gt;
===Pine wood===&lt;br /&gt;
Cutting and engraving tested&lt;br /&gt;
20mm thickness cut successfully&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Leather#Tanning_methods Leather]&lt;br /&gt;
&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;

&lt;br /&gt;
===Acrylic===&lt;br /&gt;
&lt;br /&gt;
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics. to learn more: [https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) Acrylic]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
3mm to 8mm has been tested both with cutting and etching.&lt;br /&gt;
Slow movement speed results in clean, smooth edges on the cut and etching can produce very interesting and varied effects which can easily be backlit.&lt;br /&gt;
&lt;br /&gt;
===Leather===&lt;br /&gt;
&lt;br /&gt;
Leather is cured/processed animal skin. Although leather is often made of cows' skin, it can also be made from the skin of pigs, goats, sheep, dogs, and cats as well as crocodiles, ostriches, and other “exotic” animals. &lt;br /&gt;
&lt;br /&gt;
There are two main kinds of leather, Vege tan and Chromium tan.&lt;br /&gt;
Vege tan is cured/treated with natural chemicals and materials to produce a clean, strong, leather of variying thicknesses.&lt;br /&gt;
vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.&lt;br /&gt;
&lt;br /&gt;
Chromium tan leather is made using Chromium sulfate. Faster to process than vege tan though not as strong. When burned Chromium Tan leather produces toxic fumes and thus cannot be used in our laser cutter.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Plywood===&lt;br /&gt;
&lt;br /&gt;
Plywood is an engineered wood made from multiple layers of thin veneer that are glued together. Each adjacent layer is rotated by up to 90 degrees to improve strength and other qualities. The layers are adhered together with glues or resins which can be toxic when laser cut which is why only plywood made for laser cutting should be used.&lt;br /&gt;
&lt;br /&gt;
We have tested up to 20mm thickness of laser cutter plywood and extensively used 3mm and 5mm plywood. It gives a beautiful engraving finish and cuts well though can burn if the power is set too high.&lt;br /&gt;
&lt;br /&gt;
To learn more: [https://en.wikipedia.org/wiki/Plywood Plywood]&lt;br /&gt;
&lt;br /&gt;
===Corflute===&lt;br /&gt;
&lt;br /&gt;
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.&lt;br /&gt;
&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;
&lt;br /&gt;

G139L&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Details=&lt;br /&gt;
&lt;br /&gt;
Our Laser cutter is a Genesis G139L, purchased from Makerspace NZ. It is a laser cutter/engraver which is the 2nd largest fully-enclosed front-loading glass-tube laser cutter that Makerspace NZ sells. This machine offers the precision to do high-detail engraving and will also cut cleanly through 18mm MDF/20mm natural pine timber in our tests with the 100W (continuous) tube.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It uses a C02(Carbon Dioxide) Laser tube. For more info on how this works see here: [https://en.wikipedia.org/wiki/Carbon-dioxide_laser C02 laser]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Disclaimer=&lt;br /&gt;
&lt;br /&gt;
Lasers are AWESOME(its all caps because its all true!)&lt;br /&gt;
and the bigger the laser the more fun, right?&lt;br /&gt;
&lt;br /&gt;
Yes and no, a laser pointer can damage a person or animals eye if pointed directly into it and a high-powered laser pointer(the kind you aren't supposed to get into the country) can cause serious and permanent damage if you look at it.&lt;br /&gt;
&lt;br /&gt;
The Genesis G139L has a 100Watt C02 Laser... your average laser pointer from the 2-dollar shop?&lt;br /&gt;
&lt;br /&gt;
Is 0.005 watts&lt;br /&gt;
&lt;br /&gt;
To put it another way;&lt;br /&gt;
&lt;br /&gt;
Our 100W C02 Laser is powerful enough to burn through 20mm of solid Pine wood... fast... while the 2-dollar laser pointer can't burn through it... or etch it it... at all.&lt;br /&gt;
&lt;br /&gt;
The Laser cutter is an amazingly cool piece of technology that we are very excited to have available BUT it is also potentially harmful if used carelessly, which is why we will have safety procedures in place to ensure we can all have fun and create amazing projects with it;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Corrugated plastic has been tested with cutting and engraving, though not many tests have been done. It is safe to use on the laser cutter however very low power settings are required.&lt;br /&gt;

===PLA 3D printed objects===&lt;br /&gt;
&lt;br /&gt;
Polylactic acid or PLA is a common bioplastic used in 3D printing. PLA is primarily made from fermented plant starch, such as corn or sugarcane, and is widely used in industry, agriculture and even medical applications. PLA filament is the most common filament used at Tinkd and can make all sorts of different objects.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Engraving and cutting has been tested with small PLA prints. low power is required as the PLA can melt and deform easily. Care also needs to be taken when using on the laser cutter as most 3D printed objects have only a thing shell of plastic and a gyroid or honeycomb interior.&lt;br /&gt;
