Material

Polypropylene (PP)

Polypropylene (PP) is one of the most versatile and common choices for industrial production, and 3D-printed PP has similar properties to injection-molded PP. Tough, fatigue-resistant, lightweight, and with exceptionally high elongation at break, PP is an ideal choice for functional prototypes of snap-fit assemblies or living hinges in automotive components, packaging, and consumer goods.
