'''STL, OBJ, and Gcode files'''
 
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]].
 
''.STL file:''
 
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].
 
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.
 
An STL file will look something like this:
 
[[File:Stl file format.PNG]]
 
You can see it is called a "3d object." This file can be moved, copy/pasted, and renamed like any other type of file.
 
 
''.OBJ file:''
 
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].
 
 
''G-code File''
 
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
Primarily you will be using a Slicer to create the Gcode for our Printers.
 
''Slicer''
 
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.

STL, OBJ, and Gcode files

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.

.STL file:

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: STL Files.

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.

An STL file will look something like this:

Stl file format.PNG

You can see it is called a "3d object." This file can be moved, copy/pasted, and renamed like any other type of file.


.OBJ file:

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: wavefront obj file.


G-code File

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 G-code. To learn about editing existing G-Code Primarily you will be using a Slicer to create the Gcode for our Printers.

Slicer

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.
