Evonik Develops PEBA Powder For 3D Printing


The new high-performance powder stands out for its high elasticity and strength and is suitable for a variety of powder-based 3D printing technologies. 3D printed parts made from the new PEBA powder show a high degree of flexibility, excellent resistance to chemicals and outstanding durability over a wide temperature range from -40 degrees Celsius to 90 degrees Celsius.

The 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. The powder is also ideally suited for the manufacture of functional 3D high-tech plastic parts – for prototypes as well as series products.

Fabian Stoever, senior product manager for polymers at EOS said, ’Flexible polymer materials significantly expand the options for additive manufacturing because they allow us to realise new, demanding applications in attractive markets. 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.’

The flexible synthetic powder was optimised for use in EOS laser sintering systems as part of an intensive development collaboration between the speciality chemicals company and the leading technology provider for industrial 3D printing of metals and polymers. It has been successfully adopted into the material portfolios of multiple service providers. EOS markets the powder material under the name ‘PrimePart ST’.
