This company list is preserved as a 2023 snapshot
This article originally described Carbon, Desktop Metal, Formlabs, Xometry and Velo3D as five disruptive additive manufacturing startups. The framing is no longer reliable as a current market guide.
The list mixed private companies, public companies, manufacturing marketplaces and equipment providers at very different stages of maturity. Ownership, financial condition, product strategy and public-market status have also changed since publication.
Why the original startup label became misleading
| Company in the 2023 article | Why a current reader needs new research |
|---|---|
| Carbon | A private production-platform company whose product, material and customer position should be evaluated from current company and customer evidence |
| Desktop Metal | Its ownership and operating status changed materially after the 2023 article |
| Formlabs | A mature private AM platform company rather than an early-stage startup in the ordinary sense |
| Xometry | A public digital-manufacturing marketplace with AM as one of several production processes |
| Velo3D | A public metal-AM equipment company whose investment case depends on current revenue, cash, margins and installed-base execution |
For example, Nano Dimension completed its acquisition of Desktop Metal in April 2025. Nano Dimension later reported Desktop Metal in discontinued operations following bankruptcy and deconsolidation. This illustrates why old company lists should not remain positioned as evergreen market research.
