New composite material developed for powder bed fusion

Share this on social media:

CRP Technology has launched a new material for powder bed fusion (PBF) processes for its Windform TOP-LINE range – the polyamide-based carbon fibre filled composite Windform RS.

The material delivers the durability, strength and flexibility required for a wide range of additive manufacturing applicationss.

Windform RS has a very high tensile strength (85.25 MPa) and an excellent ductility (elongation at break of 9.46%) and a low density (1.10 g/cc).

Engineer Franco Cevolini, CEO and CTO of CRP Technology, commented: “To date there is no material upon the 3D printing market that can compete with Windform RS: the combination of high resistance and high resilience makes it unique in the AM world.”

The high resilience/strength properties enable the new material to withstand shocks at various ranges of temperature, even sub-zero (it has been successfully tested to –40°C).

More about Windform RS

  • Windform RS has been rated HB according to the flammability UL 94 test; moreover, it exhibits waterproof characteristics down to just 1 millimeter part thickness.

  • Windform RS is suited for tough, intricate and complex 3D printed PBF parts, robust functional prototypes and heavy-duty end-use applications withstanding harsh environments.

  • Windform RS is ideal for custom production, preseries parts and mission-critical components for the most demanding industries such as aerospace, military, robotics, motorsports, automotive and marine.

“CRP Technology has been always working hard to bring forward customizable PBF 3D printing solutions for any scenario," said Cevolini. "We have always anticipated the requirements of the market, and the most recent analysis supports our vision: according to the latest surveys additive manufacturing adoption is increasing significantly as well as moving prototypes into production and scaling the manufacturing of production parts. Moreover, the use of 3D printing for production parts is expected to double over the next 3 to 5 years.”
