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.
