Mantle Inc, San Francisco, California, USA, has announced the addition of 420 stainless steel to its Additive Manufacturing materials portfolio. Renowned for its high strength, hardness, corrosion resistance, and ability to be polished, 420 stainless steel will enable engineers and manufacturers to produce production-grade tooling up to 80% faster

Mantle’s 420 stainless steel is chemically equivalent to traditional 420 stainless steel, and is a preferred mould material for a wide range of tooling applications, including components with conformal cooling and medical device tooling.

“We are excited to launch this material and make it available for all of our customers,” stated Ted Sorom, Mantle’s co-founder and Chief Executive Officer. “By combining the speed and cost reductions enabled by Mantle’s tooling-focused printing system with 420 stainless steel, we help 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 critical in the medical device industry. This announcement emphasises Mantle’s commitment to the continuous improvement of their precision tooling technology,” commented Melanie Sprague, SVP, Healthcare PMO and Applications at Spectrum Plastics Group, a DuPont Business. “We look forward to leveraging this material and the Mantle platform to continue providing our customers with the highest-quality medical devices.”

Expected to be released to customers in the second half of 2024, Mantle’s 420 stainless steel is the next material in its family of flowable metal pastes. Like other Mantle steels, 420 stainless steel does not require any modifications to toolmaking workflows for secondary operations such as texturing, polishing, welding, and machining.
