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.

SLS 3D Printing with PA11.5: Precision and Performance

The PA11.5 powder combines impact resistance, high durability, and superior elasticity, delivering professional results in every print. Ideal for medical parts, footwear, electronics, and engineering applications.

To achieve top-quality prints, maintaining a stable bed temperature is key. If an “orange peel” texture appears, increasing the temperature by +0.5 °C improves layer adhesion and ensures a smoother, more uniform finish.

Using Sinterit Studio with SUZY and Lisa X printers, every parameter is precisely controlled, ensuring consistent and repeatable results. PA11.5’s mechanical properties allow creating parts that withstand dynamic loads without compromising flexibility or durability.

Powder Refresh: Economy and Sustainability

PA11.5 has a 30% refresh rate, allowing powder to be reused in an efficient and cost-effective way. After each print, only the minimum amount of fresh powder recommended by the software is added, ready to mix and start the next print.

Properly mixing used powder with fresh powder ensures stable mechanical properties and uniform finishes across all parts. Even completely new powder can behave slightly differently, so small adjustments in bed temperature may be needed to maintain visual and structural quality.

With the initial powder pack, production continues by adding only fresh powder, reducing costs while maintaining a steady workflow without compromising part reliability or performance.

PA11.5 doesn’t just print parts; it provides design freedom, strength, and efficiency in every project, from prototypes to serial production.
