Additive Manufacturing (AM) has been maturing significantly over last decade and has now been identified by all major Space Agencies as key enabling technology. AM is now used to build models, prototypes, tooling, and produce parts in plastic, metal, ceramic, and composite materials. Its advantages are derived from the additional design freedoms gained that allow novel complex geometries to be realised at little additional manufacturing costs. Hardware can be produced directly from the computer-aided design (CAD) model with minimal tooling and delivery times can often be reduced.
