PA11.5: a new standard for flexibility and impact resistance on SUZY and Lisa X

At Sinterit, we are constantly looking for new materials that bring real value and usefulness to our customers. Every launch is guided by the idea of expanding design freedom and production possibilities. Today, we’re proud to introduce PA11.5, a versatile polymer that now joins our portfolio as the newest option for SUZY and Lisa X.

By combining toughness, flexibility, and cost-efficiency, PA11.5 delivers practical advantages for both compact and professional SLS workflows, further strengthening our mission to provide accessible and powerful additive manufacturing solutions.

From footwear to electronics – practical applications

The combination of durability, elasticity, and affordability makes PA11.5 a material well suited to everyday applications. In the medical sector, it is ideal for orthopedic braces and orthoses, where repeated stress and flexibility are crucial. In the footwear industry, it supports the production of custom insoles and inserts, combining comfort with longevity.

For engineers and designers, PA11.5 is equally valuable in protective housings, covers, and enclosures for consumer electronics, where impact resistance directly extends product lifespan.

For those especially interested in footwear applications, we have prepared a dedicated case study in collaboration with Fußorthopädie Paul Hast GmbH, focusing on the production of shoe insoles with PA11.5. This real-world example highlights the material’s performance in an application where both comfort and durability are essential.

Position in the portfolio

Each of Sinterit’s powders excels in its own area, and PA11.5 takes its place as another balanced, versatile option that complements the existing range:

When set against PA11 Onyx, which delivers exceptional strength and elongation at break, PA11.5 stands out as a more economical and practical alternative: it prints without nitrogen, has a lower refresh ratio, and even provides slightly better impact resistance in certain applications.

Compared to PA12 Smooth, which remains the material of choice for the finest surface finish and micro-detail reproduction, PA11.5 offers much higher flexibility for applications that demand elasticity.

Versus PA12 Industrial, which is best when maximum stiffness and dimensional accuracy are required, PA11.5 provides superior impact resistance, opening new possibilities for parts exposed to dynamic loads.

A material for both SUZY and Lisa X

The arrival of PA11.5 is a meaningful expansion for our users. For SUZY, it represents a second material option, giving designers a chance to produce more flexible and shock-resistant parts at low cost. For Lisa X, PA11.5 offers an additional polymer that balances performance with efficiency, making it easier to choose thsuzye right material for the job without overspending.

Whether you’re prototyping or producing functional end-use parts, PA11.5 makes both our compact and professional printers even more versatile.

PA11.5 is now available for SUZY and Lisa X. With its unique combination of impact resistance, flexibility, and affordability, it is the smart choice for professionals and creators who demand more from their SLS prints.

And for those who want to see it in action, don’t miss our case study with Fußorthopädie Paul Hast GmbH, showcasing how PA11.5 is used to create durable and comfortable shoe insoles.
