Shapeways
Shapeways is an Eindhoven-based 3D printing and digital manufacturing company that lets individuals and businesses upload 3D files and receive custom parts made through additive manufacturing, CNC machining and injection molding. Founded in 2007 inside Royal Philips, it pioneered a public 3D printing service and marketplace, went public via SPAC in 2021, filed for bankruptcy in 2024, and was relaunched in December 2024 by its original founders and the profitable Eindhoven factory team with a renewed focus on B2B customers, sustainability and operational stability.
Divergent
Divergent Technologies is a Torrance, California digital-manufacturing company behind DAPS, the Divergent Adaptive Production System - an end-to-end platform that pairs AI-driven generative design, metal 3D printing, and software-defined robotic assembly to produce complex automotive, aerospace, and defense structures without part-specific tooling. The same system that builds the record-setting Czinger 21C hypercar now turns out missile airframes and drone aerostructures for U.S. defense primes.
Gamma Alloys Inc
Gamma Alloys is a Santa Clarita, California advanced-materials company that reinforces aluminum with homogeneously distributed nano-ceramic particles to create metal matrix composites that are stiffer, stronger, more wear-resistant and stable across a wider temperature range than conventional aluminum. Its materials ship as wrought stock (bar, tube, plate), additive powders and additive wire for metal 3D printing, and are aimed at aerospace, defense, automotive, motorsports and even luxury goods. Founded in 2008 and led by CEO Mark Sommer, the company drew an investment from Boeing HorizonX Ventures in 2017 and partners with precision manufacturer Del West USA.
Seurat Technologies
Seurat Technologies is a Massachusetts-based contract metal manufacturer built around Area Printing, a laser powder bed fusion process invented at Lawrence Livermore National Laboratory. Instead of melting metal powder one point at a time, Seurat uses millions of tiny laser points to print entire areas at once, decoupling resolution from speed. The company doesn't sell printers; it runs its own clean-energy print factories and sells finished parts at costs meant to rival casting, forging, and machining, with the goal of reshoring high-volume metal manufacturing and cutting its carbon footprint.
