A slicer is toolpath generation software used in 3D printing processes to send the conversion of a 3D model into specific instructions for the printer. It converts a model in STL format to printer commands in g-code format for use in fused filament fabrication. These instructions are meant for independent learners - it is a requirement that students can simulate the manufacture of their products. Once a student has drawn their item and exported as an STL file they can follow these instructions to add evidence to their project folders. Using these instructions students will be able to show their computer drawings (CAD), examples of G-Code (CNC) and a simulation of the manufacture (CAM).

Onshape Computer Aided Design (CAD) software 34 page tutorial booklet for independent study. The first 2 pages I print back to back as the account set up instructions and a page of keyboard short-cuts. Note, in the account set up you will need to add your schools website address in the space provided. The rest of the booklet I photocopy back-to-back and stapled - colour copying is great if available. I have used this 34 page booklet with students with a range of abilities, it gives a good starting point and supports further independent CAD activities.
