This 2023 stock list is no longer a current investment universe
This article originally reviewed a group of additive manufacturing and 3D-printing stocks using information available in April 2023. It is now preserved as a historical market snapshot.
Several companies in the original list were acquired, taken private, delisted, restructured or materially changed their additive-manufacturing exposure. The original descriptions and ticker references should not be used for current investment decisions.
Examples of changes since publication
| Company from the original article | Material change after the 2023 snapshot |
|---|---|
| SLM Solutions | Nikon completed the squeeze-out and made Nikon SLM Solutions a wholly owned subsidiary in 2023; it is no longer a standalone public AM stock. |
| Fathom Digital Manufacturing | CORE Industrial Partners completed a take-private acquisition in 2024. |
| Desktop Metal | Nano Dimension completed the acquisition in April 2025. Nano Dimension later reported Desktop Metal in discontinued operations following bankruptcy and deconsolidation. |
| Markforged | Nano Dimension completed the acquisition in April 2025 and announced an agreement in May 2026 to sell Markforged to Stratasys. |
| Nano Dimension | The company’s investment case and AM asset structure changed substantially through acquisitions, divestiture plans and a proposed strategic combination. |
These examples are sufficient to make the original static list unsuitable as an evergreen investment guide. Current research must start from today’s ownership, listing, segment reporting and financial statements.
