Used by AQA
Paper 1
Revise: Prototyping tools and processes3D printing builds a three-dimensional object by adding material in successive layers from a CAD model, a design made using computer-aided design software. Unlike milling, it builds up the required shape rather than cutting it from a larger block.
Distinguish 3D printing, which builds a shape, from printing, which adds an image or decoration to a surface.
