To help manufacturers produce rigid, chemically resistant functional parts in high volumes, UK provider of Stratasys 3D printing solutions, Tri-Tech 3D, has made SAF Polypropylene (PP) available to its users.

The latest in Tri-Tech 3D’s range of Selective Absorption Fusion (SAF) materials, SAF PP enables high nesting density while maintaining "exceptional" surface finish and dimensional accuracy.
SAF PP is designed to be used exclusively on the Stratasys H350, a powder bed fusion (PBF) additive manufacturing (AM) system — and can help deliver production-grade polypropylene parts for high-volume demands. It offers superior chemical resistance, and lightweight and watertight properties. Combined, these properties mean that, when used on the H350 platform, SAF PP achieves consistent quality and reliable results across large builds — supporting both prototyping in research and development (R&D) teams and functional end part production on the factory floor.

The new material also offers a high level of accuracy with uniform surface aesthetics and can maintain an "exceptional" surface finish, making it ideal for printing smooth end use parts. Furthermore, it offers high weldability and adhesion, meaning it can support the creation of even larger assemblies, such as automation components.
“SAF PP is setting a new standard for polypropylene in powder bed fusion (PBF), offering unmatched resilience and flexibility compared with previous materials,” explained Brett Turner, Stratasys sales specialist at Tri-Tech 3D. “The material’s thermal control and chemical stability is a real bonus. It improves part consistency, making it suitable for a wide range of prototyping and mass-production applications, including complex end-use parts — which can be challenging to produce.
“Supported applications range from ankle foot orthosis and foot inserts to automotive components like housings and ducting,” added Turner. “Being able to produce these components accurately and quickly and with a low cost per part is a game-changer, and SAF PP has strengthened our PBF offering no end.”
