Prototyping and manufacturing by additive fabrication
 Additive fabrication (AF) technology, such as laser sintering (LS) and fused deposition modeling (FDM), encompasses a wide range of applications. The earliest was rapid prototyping to support design, concept modeling, fit/function testing, and pattern making without the need to construct expensive tooling for prototypes and test articles. Manufacturers also are using AF to produce jigs, fixtures, drill guides, and other manufacturing and assembly tools.

In contrast to crosslinking thermosets, whose cure reaction cannot be reversed, thermoplastics harden when cooled but retain their plasticity; that is, they will soften and can be reshaped repeatedly by reheating them above their processing temperature. Less-expensive thermoplastic matrices offer lower processing
