SAN FRANCISCO, CA – April 30, 2024

• Expands upon existing Mantle value of reducing the time, cost, and labor to produce tooling, especially for medical device and clean room applications, where stainless steel is used
• Reduces the time and cost to produce conformally cooled tooling components
• Mantle’s 420 Stainless Steel is chemically equivalent to traditional stainless steel; no changes are required if performing secondary operations
• Will be deployed via an over-the-air software update to Mantle’s customers

Mantle, the leader in metal 3D printing technology for toolmaking, announced today the release of its 420 Stainless Steel material. This material addition improves toolmaking processes, enhancing speed and efficiency while reducing labor requirements, which is especially beneficial in industries such as medical that require corrosion-resistant tooling.

Mantle’s 420 Stainless Steel is chemically equivalent to traditional 420 stainless steel, which is renowned for its high strength, hardness, corrosion resistance, and polish ability. It is a preferred mold material for a wide range of tooling applications, including components with conformal cooling and medical device tooling. Mantle’s 420 Stainless Steel allows manufacturers to rapidly produce production-grade tooling during prototyping and product development, thereby shortening the time to produce steel tooling for validation part molding by as much as 80 percent. 

“We are excited to launch this material and make it available for all of our customers, ” said 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 emphasizes Mantle’s commitment to the continuous improvement of their precision tooling technology,” 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.”  

Enhancing Tooling Applications with 420 Stainless Steel

Mantle’s 420 Stainless Steel is especially beneficial for tooling applications that employ conformal cooling channels. These channels, only achievable through additive manufacturing, enable more efficient cooling than traditional cooling methods, improving molding performance and reducing cycle times. Mantle’s 420 Stainless Steel has excellent corrosion resistance and eliminates the concern of conformal cooling channels clogging due to rust.  

Examples of key applications in 420 stainless steel include:

• Deep-ribbed medical device component mold insert printed with Mantle 420 Stainless Steel. This tool is ideal to fabricate with Mantle’s technology as the deep ribs would otherwise have required extensive sinker-EDM work, adding substantial cost and time. With Mantle, the insert can be printed in just 2.5 days.

• Medical luer fitting mold insert printed with Mantle 420 Stainless Steel. Twelve tool variations can be printed, fully unattended, in just 3.5 days.

The Only Metal 3D Printer Built for Tooling

Mantle’s precision metal 3D printing technology has been recognized as the premier solution for printing precision tooling, meeting the industry’s stringent requirements for accuracy, surface finish, and tool steel properties that professional toolmakers demand. Mantle’s 420 Stainless Steel is the next material in its family of Flowable Metal Pastes, which are precisely tuned to produce best-in-class accuracy and surface finish. Like all other Mantle steels, Mantle’s 420 Stainless Steel requires no modifications to toolmaking workflows for secondary operations such as texturing, polishing, welding, and machining.

Mantle’s 420 Stainless Steel will be released to customers in the second half of 2024. Customers will deploy Mantle’s 420 Stainless Steel without any modifications to hardware; only an over-the-air software update is required.

Attendees of NPE2024, the largest plastics trade show in the Americas, held in Orlando May 6-10, will have the opportunity to witness firsthand the transformative potential of Mantle’s technology. The company will showcase examples of printed steel tooling applications, including those printed with Mantle’s 420 Stainless Steel.
