Additive manufacturing is a popular activity in schools, with the advent of relatively cheap 3D printers.

This project covers the use of a desktop 3D printer, using PLA filament, extruded through a heated nozzle.

The same safety considerations should be borne in mind when using other 3D printers, or rapid prototyping machines.

This short video takes you through the main points that need to be considered when putting together a risk assessment record for the use of a 3D printer in school.

A list of test machines that could be used to carry out portable appliance testing (PAT).

The cutting and shaping of compliant and resistant materials using machines controlled by a computer (CNC machines). Cutting / soluble oil is often used when metals are being shaped.
