Orbital Matter offers an on‑orbit construction platform that 3D‑prints large, monolithic structural booms using a UV‑cured fluid called SPACECRETE, which hardens in seconds into joint‑free, space‑grade concrete. This enables satellite operators, space‑based data‑center developers, and station builders to deploy extensive solar arrays, radiators, and antennas without folding mechanisms, reducing launch mass, complexity, and cost while scaling economically with size.

Spacecraft and satellite structures are limited by the size of rocket fairings, requiring complex folding mechanisms, hinges, and motors that increase risk, cost, and design constraints. This prevents the deployment of large solar arrays, radiators, and antennas needed for power‑intensive constellations, space data centers, and multi‑module stations.
Orbital Matter provides an on‑orbit construction platform that fabricates continuous, rigid structural booms directly in space. Using a UV‑cured, fluid‑to‑solid material called SPACECRETE, the system 3D‑prints monolithic beams ranging from 10 m to over 100 m without joints, hinges, or moving parts. The process requires low power, eliminates thermal complexity, and hardens within seconds, enabling rapid deployment of large‑area components such as solar panels, radiators, and antennas. By building infrastructure in orbit rather than launching pre‑folded hardware, the platform reduces launch mass, simplifies system architecture, and lowers overall cost as structure size increases. A roadmap of demonstrator (2024‑26), customer‑focused (2026‑28), and full construction missions (2030) supports progressive scaling toward kilometer‑long space infrastructure.
Primary customers are satellite operators, space‑based data‑center developers, and agencies building multi‑module space stations that need large, reliable structural elements deployed in orbit.
