The chemicals specialist Evonik, has recently developed, Peba powder, a material that is suitable for 3D printing applications. According to the company, the powder would present high elasticity and strength capacities.
3D printed parts made from the new PEBA powder present a very good flexibility, excellent resistance to chemicals and outstanding durability over a wide temperature range from -40°C to 90°C. The powder is also ideally suited for the manufacture of functional 3D high-tech plastic parts – for prototypes as well as series products.
“Flexible polymer materials significantly expand the options for additive manufacturing because they allow us to realize new, demanding applications in attractive markets,” says Fabian Stoever, senior product manager for polymers at EOS, the global technology and quality leader for high-end solutions in the area of additive manufacturing from Germany. “In addition, the variety of materials not only enables us to produce individual high-tech functional components, but also to develop much more sophisticated 3D concepts that make use of the entire material range.”
Evonik’s PEBA material is suitable for a variety of powder-based 3D printing technologies such as laser sintering (LS), high speed sintering (HSS) or binder jetting.
Collaboration between Evonik and EOS
The flexible synthetic powder was optimized for use in EOS laser sintering systems. EOS markets the powder material under the name “PrimePart ST”.
Furthermore, the material has demonstrated very good performance with other service providers.
“New innovative products that are developed in bespoke projects in close cooperation with our customers form an important cornerstone of our organic growth,” notes Thomas Große-Puppendahl, head of the Engineered Products Product Line at Evonik.
The development of the flexible high-performance powder expands Evonik’s existing product portfolio of synthetic materials for 3D printing. The specialty chemicals company also produces polyamide 12 powders (PA 12), which have been used in 3D printing for over 20 years.
