New polymer powder for 3-D printing

| By Chemical Engineering

Evonik Industries

This company has developed a new polymer powder for applications in a higher-temperature range as part of its polyamide 6 series. The product further expands the company’s portfolio of high-performance materials for powder-based 3-D printing technologies. The new polyamide powder features high mechanical strength, as well as excellent chemical and temperature resistance. Its heat deflection temperature (HDT B) is around 195°C. Moreover, the powder material stands out for its low water absorption — below 3% — which has a positive effect on processability in 3-D printing and the dimensional stability of printed 3-D components (photo). The new polymer powder has a nearly round grain shape, improving the flowability, which makes it suitable for all powder-based 3-D printing technologies. — Evonik Industries AG, Essen, Germany
