Evolve Additive Solutions Shuts Down and Auctions Its STEP Technology

What STEP Promised

Evolve Additive Solutions spent eight years trying to turn Selective Thermoplastic Electrophotographic Process into a production-ready alternative to injection molding. The Minnesota-based company claimed its machines could print fully dense thermoplastic parts at speeds up to 50 times faster than conventional 3D printing, with surface quality and isotropic strength comparable to molded parts.

That pitch attracted serious money. LEGO Brand Group and Stanley Black & Decker participated in a $19 million round in 2018. A $30 million extension in 2021 pushed total funding to $55 million. By then Evolve had shipped its first commercial SVP system, though adoption remained limited.

Why It Fell Apart

The company never reached the volume production scale its investors expected. STEP Parts Now, a production service launched at Formnext 2021 and run with partners in the US and Europe, did not generate enough revenue to sustain operations. Consolidation across the additive industry over the past two years squeezed smaller players who could not match the pricing power of Stratasys, 3D Systems, or better-funded Chinese systems makers.

Evolve's technology was solid on paper, but the path from interesting process to profitable machine business turned out longer and costlier than planned.

The Liquidation

Grafe Auction is handling a site-by-site liquidation starting at Evolve's Edina, Minnesota headquarters. Bidding closes on September 17, 2026. Additional catalogs covering Rochester, New York and Minnetonka, Minnesota are scheduled for October. The inventory includes SVP PA850 toner cartridges, industrial linear actuators, Gocator 3D laser profilers, and the production machines themselves.

The question now is whether STEP's intellectual property survives the shutdown. Fortify's patents found a buyer when Tethon 3D acquired them in March 2026. Whether any buyer emerges for Evolve's portfolio will determine if the technology disappears entirely or gets another shot at commercialization under new ownership.

Evolve's end is another data point in a brutal year for additive manufacturing startups. Würth Additive Group closed in June. Hartwig ended its AM business line in late 2025. Rapid.Tech 3D was discontinued after 22 years. The companies that survived 2026 are those with either massive installed bases or direct access to aerospace and defense budgets. High-speed thermoplastic production sounded promising. It was not enough.
