Rapid prototyping (RP) includes a variety of manufacturing technologies,
although most utilise layered additive manufacturing. However, other technologies used for RP include high-speed machining, casting, moulding and extruding.
While additive manufacturing is the most common rapid prototyping
process, other more conventional processes can also be used to create prototypes.
These processes include:
- Subtractive - whereby a block of material is carved to produce the desired shape using milling, grinding or turning.
- Compressive - whereby a
semi-solid or liquid material is forced into the desired shape before being solidified, such as with casting, compressive sintering or moulding.
