3D printing (3DP) materials for desktops and some other machine types are getting far more specialized. They’re also becoming more widely available, and from more sources: the number of manufacturers tossing their hats in the ring is growing, such as Natureworks, makers of the leading Ingeo PLA biopolymer. So is the number and variety of what each manufacturer offers.

This Design News slide show provides a review of what’s new: a space-qualified ABS filament, a PLA filament containing 30% aluminum powder, a stereolithography (SLA) resin that rivals ABS for making load-bearing parts, carbon fiber-reinforced filaments, aerogel metamaterial, and conductive PLA filament. Materials suppliers are also making their packaging more useful, such as extended-life canisters and larger spools made of bio-based materials.
