3D Printing

Intro to 3D CAD design

In order to get something 3D printed, you first need to design it 3D space. for this you need computer aided design (CAD) software. One easy to use example of this is TinkerCAD.

Start the tinkerCAD turorial here and create some basic shaps.

Slicing

The second step in 3d printing is slicing: the process of converting your design into instructions for the 3D printer. In some instances, its also called pre-processing.

Different 3d printers use different slicing software but they all do the same thing, make instructions for the 3d printer.

Most slicing software can process .stl files so we need to export our tinkerCAD shape in this format.
