Mantle launches 420 stainless steel for P-200 metal 3D printing system

Coat has introduced a 420 stainless steel material for its P-200 metal 3D printing system for toolmaking.

This material, Mantle believes, will improve the tool manufacturing process by increasing speed and efficiency while reducing labor requirements. According to the company, this will be especially beneficial in industries that require corrosion-resistant tools, such as healthcare.

The Mantle 420 stainless steel is said to be chemically equivalent to traditional 420 stainless steel and features high strength, hardness, corrosion resistance and polishing ability. It is a preferred molding material for components requiring conformal cooling channels and medical device tooling, where the material’s excellent corrosion resistance helps eliminate the concern of clogging of conformal cooling channels due to rust.

“We are excited to launch this material and make it available to all our customers,” said Ted Sorom, Co-Founder and Chief Executive Officer of Mantle. “By combining the speed and cost savings made possible by Mantle’s tool-centric printing system with 420 stainless steel, we are helping our customers set a new standard for the speed of their product development.”

“We are incredibly pleased with Mantle’s introduction of their 420 stainless steel, a mold material that is critical in the medical device industry. This announcement highlights Mantle’s commitment to the continued improvement of their precision tooling technology,” said Melanie Sprague, SVP, Healthcare PMO and Applications. at Spectrum Plastics Group, a DuPont Business “We look forward to using this material and the Mantle platform to continue to provide our customers with the highest quality medical devices.”

Mantle’s 420 stainless steel is the newest material in the family of liquid metal pastes, which have been finely tuned in an effort to produce “best-in-class accuracy and surface finish.” Like all Mantle steels, Mantle’s 420 stainless steel requires no adjustments to tool shop work processes for secondary operations such as texturing, polishing, welding and machining. The material will be released to customers in the second half of 2024, with customers able to deploy the 420 stainless steel without any hardware modifications; Only an over-the-air software update is required.
