PP (polypropylene) is a low density, transparent polymer that offers good chemical and fatigue resistance, which makes it a great choice for prototyping. PP has a high melting point, so will require a 3D printer with a heated bed.
Verbatim PP is a high heat-resistant 3D printer filament that was engineered for reliable and high-quality prints. It is manufactured to very tight tolerances, to ensure consistent filament feeding during the printing process and stable prints to finish. This filament is used for a wide variety of industrial projects including tooling and prototyping.
