Polymer powder for 3D printing in higher temperatures
Driving forward its commitment in the attractive 3D printing market, the specialty chemicals company, Evonik, has developed a new polymer powder for applications in higher temperature range as part of its polyamide six series. The product further expands Evonik’s portfolio of high-performance materials for powder-based 3D printing technologies.
Evonik’s 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 three percent, which has a positive effect on processability in 3D printing and the dimensional stability of printed 3D components.
“New, ready-to-use materials that are optimally adapted to the individual printer and expand the range of application to higher temperatures move the 3D printing industry one step further toward series production,” said Mark Zhao, Founder and CEO of TPM 3D Chinese technology company for Selective Laser Sintering (SLS). “We are seeing strong demand for 3D solutions in the higher temperature range, for example in the automotive and electronics industries. That’s why we were pleased to launch the new temperature-stable material together with Evonik.”
The new polymer powder in Evonik's polyamide six series with its nearly round grain shape stands out for excellent flowability and application properties, making it suitable for all powder-based 3D printing technologies. A proprietary procedure of Evonik is employed to produce the high-temperature material at the company’s Marl site.
