Evonik has developed two new copolyester powders for 3D printing. According to the manufacturer, they combine high elasticity and flexibility with good rebound resilience. The copolyesters are suitable for conventional powder-based 3D printing technologies, such as selective laser sintering (SLS). According to Evonik, they feature good flow properties at their processing temperature. This allows the entire height of the powder bed to be used efficiently in 3D printing. After printing, they remain tough and flexible without sacrificing surface quality.
Print Directly in Black without Subsequent Coloring
The copolyesters are available in both white and black. 3D-printed parts are typically manufactured in white and then colored as necessary. With the pigmented powder, parts can be printed directly in black. Subsequent coloring is no longer necessary.
Investment in Three Product Areas: TBA, DiB and TMH
Evonik is investing around €15 million in its C4 production network in Marl. Targeted debottlenecking measures will increase the local production capacity for so-called isobutene derivatives by well over 50% by December 2021. In addition, logistics will be further expanded
