First available PA11 for the desktop SLS 3D printers

Since the introduction of Sinterit Lisa, the first SLS desktop 3D printer, selective laser sintering has been used to address more and more problems in many areas such as prototyping, medical applications, production, and design. Sinterit is going forward in this process introducing the first PA11 powder ready to use in desktop SLS 3D printers.

In this military glass case printed with new Sinterit Lisa Pro using PA11 Onyx, it was essential to produce a durable and individually shaped design to fit particular features of combat glasses. Printed as one piece, it doesn’t need assembling or any different parts such as screws or hinges to be functional.

Thanks to Sinterit PA11 Onyx properties, especially high elongation at break, it can be opened and closed thousands of times. In combination with its high impact, abrasive and chemical resistance PA 11 Onyx ensures robustness – the product will be useful and long-lasting in any hostile environment.

PA11 Onyx is also perfect for creating robust, custom casings. – Our clients use a lot of electronic devices, like Raspberry Pi, that need a proper, individually made housing that can endure in unfriendly conditions – says Konrad Glowacki, one of Sinterit co-founders. – They are looking for durable materials but also require some elasticity and high-temperature resistance. PA11 Onyx delivers that – he adds.

What are the benefits of PA11 Onyx powder in additive manufacturing?

PA11 Onyx has high elongation at break, and it is highly impact resistant. With this benefits in mind, engineers and product designers could carry out a lot more functional tests without damaging the part. It makes a perfect solution for functional final moving parts, enclosures, latch systems, handles, sporting goods, hinges, and fall-proof elements. The benefits include resistance against chemicals and extreme weather conditions.

– Traditionally PA11 has not really been widely used due to its challenges with repeat accuracy on old generation Laser Sintering machines – says Janne Kyttanen, a pioneering digital sculptor creating multidisciplinary work at the intersection of 3D printing, virtual & augmented reality. – Reason for that is controlling heat on large powder beds, which all of the previous machines have had. When you bring this material to desktop size, you are changing the game. Small size platforms open up new opportunities not just in PA11, but also beyond – he ads.

PA11 Onyx is a high performance polyamide-11 lightweight bioplastic produced from plant-based renewable resources. Compared to other polyamides from this group such as PA12 it delivers outstanding thermal and chemical resistance, accompanied by impact resistance and enhanced flexibility simply on your desktop.

From the desktop SLS 3D printers available on the market today, only Sinterit Lisa Pro has an option to print from PA11 Onyx because it uses a nitrogen chamber to produce the best environment for laser sintering. The printer was launched in May, and the shipment of the first ones is in process.

The company will be present at the Formnext in Frankfurt, Germany (from November 13-16th, booth G41 Hall 3.1) with both printers, flagship Lisa and this year special Lisa Pro. Along with the devices, Sinterit is planning to launch several new powders. As for now, the company has in its offer PA12, PA11 Onyx and two TPU materials – Flexa Black and Flexa Grey. With this spectrum, you can reach for powerful 3D prints from SLS technology.
