New Windform RS composite material for PBF shows off top tier mechanical properties

Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

CRP Technology is introducing the new proprietary material Windform RS, a polyamide-based carbon fiber-filled composite that shows exceptional mechanical characteristics. Windform RS is the tenth material of the Windform TOP-LINE range of composite materials created, formulated and developed by CRP Technology for Powder Bed Fusion process with composite polymers fibers-reinforced.

“CRP Technology has been always working hard to bring forward customizable PBF 3D printing solutions for any scenario”, said Engineer Franco Cevolini, CEO and CTO, CRP Technology. “We’re building upon CRP Technology’s legacy in materials for AM to create new ones at the highest level for our customers’ benefit, and Windform RS proves it: our focus on innovation led to the creation of a composite material with a very high tensile strength of 85.25 MPa, that has at the same time excellent ductility with elongation at break of 9.46% and low density of 1,10 g / cc.

“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 Windform RS unique in the AM world.”Franco Cevolini, CEO and CTO, CRP Technology

Windform RS is resistant to damage, shock, vibrations, deformations and high temperatures. Its high resilience/strength properties allow it to withstand shocks at various ranges of temperature, even sub-zero. CRP reports that the materials has been successfully tested to – 40 °C. It is resistant to water and liquid absorption down to just 1 millimeter part thickness and has been rated HB according to the flammability UL 94 test.

Windform RS provides enhanced functionality, offering product designers and engineers greater flexibility and speed in developing intricate parts that must be resistant to fatigue, shocks, high and low temperatures. Moreover, it offers excellent ease of printing during the manufacturing of parts.

“This is a very important property—Cevolini stated—not to be underestimated. Many materials on the AM market claim high performance, but their “printability” turns to be difficult during the sintering of the part, thus complications arise leading to bad quality and poor performance. This does not happen with Windform RS and with all our composite materials: the Windform TOP-LINE range offers high performance and maintains optimal ease of print, which turn to a superior final product.”

“As CRP Technology, we always look toward the future not just for our company, but for those sectors where the demand for high-value and high-performance parts is fast-growing,” Cevolini continued. “Windform RS is an astounding advancement in engineered materials, offering a unique opportunity with the durability, strength and flexibility needed for a wide range of additive manufacturing applications.

Indeed, 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. THis makes it and ideal for custom production, preseries parts and mission-critical components for the most demanding industry solutions for applications in segments such as aerospace, defense, robotics, motorsports, automotive and marine.
