Technology & Products
Key Products
["Terran R - Medium-to-heavy lift rocket (in development)", "Aeon R Engine - 3D-printed LOX-methane engine (269,000 lbf thrust)", "Stargate - Worlds largest metal 3D printer", "Wire Arc Additive Manufacturing technology", "Terran 1 (retired) - First 3D-printed rocket to reach space"]
Technological Advantage
Advanced additive manufacturing enables rapid prototyping, lower lead times, and cost-effective, scalable production of launch vehicles.
Differentiation
Value Proposition
Rapid iteration and significant cost savings via large-scale 3D printing, enabling faster production and customization of rockets.
How They Differentiate
Relativity differentiates through its Stargate 3D printer (worlds largest metal printer) and vertically integrated manufacturing, though now using hybrid approach. Terran R designed for reusability with 13 Aeon R engines on first stage.
