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.

Key Benefits
- Exceptional impact resistance (up to 117 kJ/m²)
- High elongation at break (up to 27%) for flexibility
- Reliable long-term performance
- Smooth surface quality, reduced post-processing
- Economical printing: no nitrogen, low refresh ratio
Compatible with SUZY and LISA X 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.
