NEW thermoplastic elastomers for powder-based 3D printing technologies
Evonik has developed two new copolyester powders to meet the growing demands of the 3D printing industry. The result of Evonik’s acquisition of STRUCTURED POLYMERS TECHNOLOGY, these innovative, high-performance materials the existing portfolio of polyamide-based powder formulations. Customers now have an even broader spectrum of products available to them, encompassing everything from flame-retardants to elastic, ready-to-use materials.
Tough yet flexible
The new copolyester powders are highly elastic and flexible, yet exhibit excellent recovery. The powders are available in white or black depending on the application, and are suitable for use in common powder-based 3D printing technologies, such as selective laser sintering (SLS). At processing temperatures, the flow characteristics of the new powder formulations are also impressive, allowing manufacturers to make efficient use of the full installation height of the powder bed during the 3D printing process.
Compared to other flexible materials available on the market for SLS, the new, ready-to-use copolyesters from Evonik remain tough and flexible after printing, with no sacrifice in surface quality.
Powder material in black and white
3D parts are typically produced in white and then dyed depending on the application. In addition to white, Evonik’s new copolyesters are now available as a black powder as well so that parts can be printed directly in that color.
