## Material Info

### About

Selective Absorption Fusion (SAF) PA11 is a high-performance, bio-based nylon powder ideal for production-grade 3D printed parts. Derived from renewable castor oil, SAF PA11 delivers outstanding ductility, high impact resistance, and excellent chemical resistance. This material is optimized for demanding applications in automotive, industrial, medical, and consumer sectors, making it a sustainable choice for strong, flexible end-use components.
