Metal Additive Manufacturing: Companies, Startups & Research

3D Systems, Nikon SLM Solutions AG, Renishaw, EOS Electro Optical Systems GmbH and Velo3D are among the companies active in metal additive manufacturing. Their work includes laser powder bed fusion equipment, systems and software for industrial parts. Oak Ridge National Laboratory is a research and deployment partner in directed energy deposition and wire arc additive manufacturing.

Freemelt AB, Elementum 3D and Wayland Additive are notable startups with distinct technology positions. Freemelt develops open-platform electron-beam powder bed fusion systems for materials research. Elementum 3D develops metal alloys and process technologies, while Wayland Additive develops the Calibur3 system using its NeuBeam electron-beam process.

Oak Ridge National Laboratory, Shanghai JiaoTong University and Huazhong University of Science and Technology are active research organizations in the field. Oak Ridge works on wire arc additive manufacturing and large-scale deposition. Shanghai JiaoTong studies materials including platinum and structural magnesium alloys, while Huazhong investigates Hastelloy X, multi-material structures and process monitoring.

Funding data records $438.8 million across 510 grants since 2020, alongside 22 funding rounds totaling $1.287 billion. These figures indicate substantial recorded funding activity, but the listed rounds and grants may span related manufacturing activity rather than funding dedicated exclusively to metal additive manufacturing.

RTX Corporation leads the listed patent holders with 36 patents in the provided data. General Electric has 23, Rtx A S has 17, and the French Atomic Energy Commission has 14. General Electric Company and Safran are also among the leading holders, with 13 and 11 patents respectively.

Patent activity is declining in the latest comparison: the 24-month window records 1,470 patents, and patent growth is -47.4% for the last 12 months versus the previous 12 months. This contrasts with sustained publication activity, so the patent trend alone does not indicate whether technical research or industrial interest has slowed.

Recent developments include a micro-CT-based fatigue-life prediction framework for laser powder-bed-fused AlSi10Mg and research on wire-arc-produced shape-memory alloy, both published in September 2026. In May 2026, Mastrex launched its MX300 dual-laser system, and Lockheed Martin advanced laser powder-bed fusion for thermal-management parts.

The main approaches include laser powder bed fusion, electron beam powder bed fusion, directed energy deposition, binder jetting and bound metal extrusion. Powder-bed fusion targets detailed parts by selectively consolidating powder. Deposition methods add material where needed, supporting larger builds and repair. Binder jetting and extrusion require debinding and sintering after shaping.

The United States leads the recorded country data with 44.8% of documents, followed by China at 21.6% and Germany at 18.3%. The United Kingdom and India are also active, with shares of 15.3% and 9.3%. These figures describe document activity, not manufacturing capacity or market share.

The listed application areas include automotive and mobility, aerospace and defense, medical and dental, energy and power generation, and industrial equipment and tooling. Aerospace and defense has 6,168 documents, automotive and mobility 6,584, and medical and dental 4,758. These applications use the technology for complex parts, specialized geometries and production or repair needs.
