What Mantle does

Mantle is a metal 3D printing company that has developed and commercialized a hybrid additive-subtractive manufacturing system purpose-built for precision tooling. Its core product, the M-Series Metal 3D Printer, uses proprietary TrueShape technology that combines bound metal paste extrusion with in-process CNC machining in a single automated system to produce mold and die components from industry-standard tool steels (H13, P2X, and 420 Stainless Steel). The technology is positioned against the $45 billion tooling market, targeting injection molders, moldmakers/tool shops, and OEMs in North America with claims of 65%+ lead-time and cost reductions, 1-3 micrometer Ra surface finish, +/- 0.001 inch per inch accuracy, and the lowest reported shrink rate (8-10%) of any sinter-based metal additive manufacturing process.

The company's revenue model is anchored on capital equipment sales (machines priced at approximately $350,000), supplemented by recurring consumables revenue from proprietary metal paste (e.g., $600 in consumables for a sample H13 print, $1,240 fully burdened), with bundled TrueShape software that automates CAM-less toolpath generation. Go-to-market is direct enterprise field sales targeting injection molding, moldmaking, medical device, and OEM customers, with named customers including Tessy Plastics, Nicolet Plastics, Heyco Products, Westminster Tool, Fathom Manufacturing, General Pattern, Westec Plastics, Xpress7, Elite Mold & Engineering, L'Oréal, and an unnamed global medical device manufacturer. Demonstrated production scale includes over one million end-use parts produced using Mantle's technology.

Mantle was founded in 2021 by Ted Sorom (CEO) and Steve Connor (CSO), raised approximately $58 million across three equity rounds (seed, Series B in 2021, and a $20 million Series C led by Schooner Capital in July 2024), and was acquired by Angstrom Group, a Tier 1 automotive and industrial supplier with 41 locations across the Americas and Europe, in November 2025. Following the acquisition, Kim Hayashi was appointed CEO in March 2026, succeeding co-founder Ted Sorom and signaling a transition into a scale-up phase under strategic ownership.

Core offering

Mantle designs, manufactures, and sells a hybrid metal 3D printing system (M-Series printer) that combines bound metal paste extrusion with precision CNC machining to produce high-hardness tool steel components for injection mold tooling. The company sells the machines (~ $350,000 each), proprietary metal paste consumables in H13, P2X, and 420 Stainless Steel, and TrueShape software that automates toolpath planning, targeting injection molders, moldmakers, and OEMs needing production-ready mold inserts and conformal cooling channels.

Product overview

Mantle offers an integrated automated toolmaking system combining hardware, software, and materials for precision injection mold tooling. The system centers on the M-Series metal 3D printer, which uses proprietary TrueShape hybrid technology merging bound metal paste extrusion with precision CNC machining to produce tooling components in industry-standard H13, P2X (P20-comparable), and 420 Stainless Steel materials. The TrueShape software suite automates toolpath programming without manual CAM expertise. The company sells its machines, tool steels, and software as a coordinated system targeting molders, moldmakers, and OEMs. Key value propositions include reducing tooling lead times by up to 75%, cutting costs by over 50%, eliminating or reducing sinker EDM operations, and enabling conformal cooling channel designs.
