	~~vege~~ tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.		Vege tan is safe to cut in the Laser cutter as the chemicals used in its processing don't produce harmful fumes. Smells horrible.

	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.		Chromium tan leather is made using Chromium sulfate.

			===MDF===
			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.

			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.

	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.		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.
