PA11.5 Powder

PA11.5 Powder for SLS 3D Printing

Tough, flexible, and reliable – PA11.5 is the smart choice for functional SLS parts.

This advanced polymer combines outstanding impact resistance, high durability, and excellent elasticity, making it perfect for demanding applications that require both strength and flexibility. With a smooth surface finish and cost-efficient processing (no nitrogen required, 30% refresh ratio), PA11.5 is as practical as it is powerful.

PA11.5 powder is supplied in convenient 10 kg bags, making it easy to handle and store.

Compatible with printers:

Applications

• Medical & Orthopedic – Orthopedic insoles, braces, and orthoses that must handle repeated stress while remaining comfortable.
• Footwear – Custom insoles and inserts that combine comfort, flexibility, and long-term durability.
• Consumer Electronics – Protective housings, covers, and enclosures where impact resistance extends product lifespan.
• Engineering & Functional Prototypes – Robust parts exposed to shocks, drops, and dynamic loads.

Key Benefits

• Exceptional impact resistance (up to 117 kJ/m²)
