Puris develops new titanium powder optimised for AM

Titanium powder from Puris

Puris, LLC has announced that it has filed a patent for Puris 5+TM, a new titanium powder formulation offering a high-strength, low-oxygen formulation specifically designed to meet the demands of Additive Manufacturing. Puris 5+ is reported to be a custom composition of Ti-6Al-4V that meets all the specifications of Grade 5.

Typically, engineers seek to balance the oxygen levels needed to obtain the desired strength properties with the increases in oxygen levels inherent in some Additive Manufacturing processes. This creates a challenge in laser melt or e-beam direct melt 3D printing, as both processes experience increases in oxygen content with each recycle of excess powder from the build box. By starting with Puris 5+, Puris claims that customers can manage this balance of oxygen and strength better throughout the life cycle of the titanium powder.

“The introduction of low-oxygen, high-strength Grade 5 titanium powder represents a major breakthrough that equips our customers to better control the oxygen pickup inherent in their processes. The result is more efficient utilisation without compromising powder strength,” stated Puris CEO Craig Kirsch.

“Puris 5+ is an exciting example of our company’s continuing leadership in advanced titanium powder for Additive Manufacturing, made possible by our deep metallurgy and Powder Metallurgy expertise,” Kirsch added. “The efficacy of AM ultimately depends on such powder quality and advancements.”
