Angstrom Fuels Automotive Growth Through Mantle Acquisition

The Angstrom Group, a major Tier 1 supplier in the automotive and industrial sectors, has announced the acquisition of San Francisco-based metal 3D printing company Mantle. The move marks a major step toward integrating additive manufacturing into automotive production, signaling a shift in how tooling and mold components are designed and manufactured.

Mantle has earned recognition for its hybrid metal additive manufacturing systems that combine precision 3D printing with CNC machining. This approach allows for the automated production of high-quality tooling components used in injection molding, significantly reducing the time and cost associated with traditional toolmaking. With the support of Angstrom’s global manufacturing network, Mantle will be able to expand its reach and accelerate adoption of its technology across the automotive supply chain.

At the center of Mantle’s innovation is its TrueShape technology, which prints metal parts layer by layer using a proprietary paste. Once printed, the parts are sintered and finished to meet production-grade tolerances. The combination of additive and subtractive processes enables toolmakers to produce mold cavities, inserts, and components in-house instead of relying on external suppliers. For the automotive sector, where tooling lead times can be lengthy, this method provides a faster and more adaptable solution.
