Sandvik Exits Additive Manufacturing Business

Sandvik has moved to exit its additive manufacturing business, signing an agreement to sell the unit to Swedish investment firm Mimir. The decision is one of the clearest signs this year that industrial AM is entering a more selective phase, where large engineering groups are reassessing whether they should own the full AM stack or concentrate on core manufacturing platforms.

The divested business sits within Sandvik’s Machining segment and includes metal powders for additive manufacturing, metal injection moulding, hot isostatic pressing and controlled expansion alloys. Sandvik has been active in AM for more than two decades, but the company has also been revising its exposure to the sector, including earlier changes to its service-provider holdings and a sharpened focus on metal powders.

For the broader AM market, the move is less a rejection of the technology than a statement about capital allocation. Powder production, qualification, customer-specific development and post-processing all require focused investment, while industrial customers increasingly demand certified, repeatable, production-ready systems rather than isolated technology demonstrations.

Mimir’s ownership may give the business a more dedicated platform for growth. At the same time, the sale underlines a wider truth for AM: growth is continuing, but the winners are likely to be companies that can connect materials, process control, qualification and surface finishing into a coherent production chain.

Research Spotlight

Philipp Gabriel, Florian Eibl, Stephan Barcikowski, Anna Rosa Ziefuss — Additive Manufacturing

This paper targets one of the most important frontiers in metal AM: seeing not just geometry or melt-pool intensity, but chemical information during the build. Robust in-situ spectroscopy and reconstruction could help move LPBF process monitoring closer to material-level quality assurance.
