HP® 3D HR PA 11

PA 11 (HP 3D High Reusability PA 11) is a bio-derived material made from renewable castor oil with exceptionally high toughness. It is ideal for producing durable, flexible parts that must withstand repeated stress and impact. Common applications include snap-fits, living hinges, sports equipment, prosthetics, and functional prototypes for automotive or industrial use. Its high elongation and strength make it well-suited for parts exposed to demanding mechanical conditions.

Polished

19 colors

Polished PA 11 parts feature a smooth, refined surface with reduced graininess compared to standard prints. The process enhances appearance and touch while retaining the material’s toughness and flexibility.

Shot Peened

19 colors

Shot peened PA 11 parts have a denser, smoother surface achieved by blasting fine media against the nylon. The finish improves fatigue resistance, reduces porosity, and gives the part a uniform matte look.

Vapor Smoothed

19 colors

Vapor smoothed PA 11 parts have a sealed, glossy surface with reduced porosity. The process enhances aesthetics, improves cleanability, and increases resistance to moisture and dirt while maintaining mechanical strength.
