Evonik’s new polyamide (PA) 6 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 features low water absorption – below 3 percent — which has a positive effect on processability in 3D printing and the dimensional stability of printed 3D components.
Demonstration part made from the new polymer powder of Evonik’s Polyamide 6 series. The high-performance material has been specially developed for applications in the higher temperature range.
“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,” says Mark Zhao, founder and CEO of TPM 3D, a Chinese selective laser sintering (SLS) machine OEM. “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 PA 6 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.
The 3D printing market is booming, posting double-digit growth rates. Evonik is a leader in the production of PA 12 powders, which have been used in additive manufacturing technologies for over 20 years. In addition to polyetheretherketone (PEEK) filament and PA 12 powders, the company's product portfolio includes flexible polyether block amide (PEBA) powders as well as a full range of additives such as dispersion agents, flow improvers or reactive modifiers.
