This page is about creating models for 3D-printing. It's mostly geared towards Sudoers using our [[Type_A_Machine|Type-A Machine]] 3D printer, but models can be made by anyone anywhere, just like word documents don't have to be made on a machine attached to a 2D printer.
This page is about creating models for 3D-printing. At Sudoroom we have a [[Type_A_Machine|Type-A Machine]] 3D printer, and a [[TAZ_4|TAZ 4]] 3D printer, but models can be made by anyone anywhere, just like word documents don't have to be made on a machine attached to a 2D printer.

3D Printers don't understand OpenSCAD or STL. They understand an extension of gcode, which is a decades-old language which sends direct instructions such as "heat to 100 degrees, move here, do this, move there, do that, cool down". In order to print a model you have to turn it into a series of 2D layers or "slices", using a program called a "slicer". Slicers output gcode. They need to be configured for a particular printer, with settings such as melting tempurature, bed size, fill style, overhang compensation, etc. Examples of slicing software:
