Mantle, the market leader in metal 3D printing technology for precision tooling, has raised $20 million in a Series C funding round. To date, the company has raised more than $61.5 million in funding.
The Series C funding round will be used to expand the market, increase manufacturing capacity to meet demand, and develop new capabilities and materials. Schooner Capital, a Boston-based private investment firm, led the round, which also included the company’s largest existing investors, Fine Structure Ventures, Foundation Capital, Corazon Capital, 11.2 Capital, and Build Collective.
Metal 3D Printing Technology for Precision Tooling
The recent push to reshoring manufacturing in the United States has highlighted the critical need for innovative solutions to address labour shortages while lowering costs and improving production efficiency. Among the numerous technologies attempting to meet this challenge, metal 3D printing has emerged as a key player, poised to redefine the future of American manufacturing.
“Mantle is poised to revolutionise the global tooling industry. The company’s advanced manufacturing platform, TrueShape, is proven to deliver significant cost savings and, more importantly, unprecedented speed for its customers. This paradigm-shifting solution is readily adoptable and sorely needed to address persistent skilled labour shortages and accelerate product development timelines for industrial toolmakers and OEMs worldwide.”
– Alexandra Manick, Principal of Schooner Capital
Amid a severe labour shortage of toolmakers and skilled tradespeople plaguing the manufacturing industry, fuelled by a workforce nearing retirement and a surge in demand for the tooling required for everyday products, manufacturers are turning to automation and cutting-edge technology solutions to overcome these workforce challenges.
“The fragile state of the global supply chain has triggered a massive reshoring initiative that sharply increased the demand for moulded parts and thus toolmaking.”
– Ted Sorom, CEO and co-founder of Mantle
Sorom added, “We’re navigating a twin set of hurdles: a toolmaking workforce in the U.S. that has shrunk by half over the past quarter-century, coupled with the rising costs and extended lead times brought on by constrained toolmaking capacities. This has driven manufacturers to seek out ground-breaking solutions. For our innovative customers, the adoption of Mantle’s tooling technology has emerged as a key strategy to enhance labour productivity, cut expenses, and drastically shorten lead times.”
Easing Labour Scarcity of Toolmakers

Heyco Products, a wire protection and electrical component manufacturer based in the United States, uses Mantle technology for in-house moulding and toolmaking.
“We purchased a Mantle system for two reasons: to reduce time-to-market for our products and to make our toolroom more efficient while attracting next-generation talent to Heyco.”
– Danny Anthony, Heyco’s Vice President of Operations
Anthony continued, “By using Mantle to print mould tooling, we have already brought a new product to market two months faster than we would have otherwise. We also increased the throughput in our toolroom by giving our toolmakers access to the latest technology that makes them significantly more productive.”
Positioned for Explosive Growth in Tooling Needs
Following a year of double-digit shipment growth, Mantle’s precision metal 3D printing technology is specifically designed to print injection mould tools, an application where other metal 3D printing methods have historically failed. This innovation reduces both the time and cost required to manufacture high-quality moulds and dies. The technology provides unparalleled precision, surface finish, and metal properties while automating tool manufacturing and reducing reliance on scarce skilled labour.
Mantle’s innovative technology has helped produce millions of end-use parts, including medical devices, deodorant packaging, and industrial components. By focusing on printing tools for mass production rather than parts themselves, the company has addressed the long-standing issues of high costs and long production times associated with tool creation for mass production. This strategic shift has resulted in cost savings for customers of more than 65 percent, as well as up to a 90 percent acceleration of manufacturers’ development cycles.
