- 3D Printing
Hacksaw
Metals & Polymers
Coping saw
Polymer or timber
Tenon saw
Timber
Jigsaw
Motor to move saw blade
- Most types of materials
Turning
Using lathe to make round parts
Milling
Rotating tool to remove metal one layer at a time.
Chemical etching
Chemicals used to remove materials
Photo-etching
Chemical etching used to make PCBs
Forming
Changes dimensions and shape of a material
Shaping
Pouring/forcing liquids into moulds to make objects
Folding
