Impact Resistance and Superior Elasticity

The PA11.5 material stands out for its exceptional resistance to impacts, drops, and repeated stress, handling dynamic loads without cracking or structural failure. Its 27% elongation allows parts to bend and adapt under pressure rather than break, ensuring optimal performance in medical applications such as splints, orthoses, and orthopedic insoles, as well as in industrial components subjected to continuous stress.

Durability and Professional Finish

Another key benefit of PA11.5 powder for 3D printing is its long-lasting performance in demanding environments, with mechanical properties that remain stable over time. Additionally, produced parts feature a smooth and uniform surface finish, reducing post-processing needs and offering a professional look straight out of the printer.

Optimized Cost in Additive Manufacturing

PA11.5 SLS enables significant operational cost savings, as it does not require nitrogen for the process and has a reduced refresh rate of 30%. This ensures more economical 3D printing without compromising quality or performance, making it a strategic material for both prototyping and serial production.
