Desktop Metal ($DM) — Delisted April 14, 2025. Chapter 11 filed July 28, 2025. Liquidated in 64 days. Once valued at $9B+ (2021 peak) after a $580M SPAC merger. Acquired by Nano Dimension for $179.3M, then collapsed. Binder jetting IP sold to Arc Impact for $7M. Foreign subsidiaries (including ExOne GmbH) sold to Anzu for $10M. Total liquidation: ~$17M from a company that raised $580M.
Markforged ($MKFG) — Acquired by Nano Dimension for $116M ($5.00/share) on April 25, 2025. No longer independently traded. The Digital Forge platform — cloud-connected industrial composite and metal 3D printers — continues within NNDM. Generated $85M revenue with ~50% gross margins in 2024.
ExOne ($XONE) — Originally acquired by Desktop Metal in 2021 for its sand/metal binder jetting technology. When Desktop Metal went through Chapter 11, ExOne GmbH (Germany), ExOne KK (Japan) were sold to Anzu Partners ($10M). ExOne Americas was sold to Arc Impact ($7M). The technology survives, but the public equity is zeroed out.
The Lesson: Revolutionary technology does not guarantee a sustainable business model. The 3D printing sector has seen over $10B in cumulative value destruction across SPACs, failed mergers, and bankruptcies. Survivors need cash, discipline, and production-grade customers.
