The best in-space manufacturing space startups
10 in-space manufacturing companies in the directory, ranked by disclosed funding ($516.5M raised between them), spanning 6 countries.
Microgravity changes how crystals grow, how alloys form and how fibers draw. These startups manufacture things in orbit that cannot be made on Earth, then bring them home.

State of the sector
As of 27 September 2026
Some companies here make things in orbit, and others bring them home or build structures there. Varda Space grows pharmaceutical crystals in capsules that return to Earth. Space Forge wants to make semiconductor materials, and BioOrbit works on crystallising proteins for cancer drugs. ElevationSpace and Atmos Space Cargo build return capsules, and ArcSpace and ThinkOrbital work on welding in orbit.
Space Forge fired its orbital furnace to 1,000°C on ForgeStar-1 in December 2025, a first for commercial in-space manufacturing. BioOrbit lost its first crystallisation unit in June 2025 when The Exploration Company's capsule failed to land, and raised a seed round in May 2026.
ArcSpace plans to fly a 12 kg electron-beam welding tool in 2027. Made In Space, which put the first 3D printer on the International Space Station, was bought by Redwire in 2020.
