About
Relativity Space is an aerospace company pioneering a new approach to rocket manufacturing through large-scale 3D printing and autonomous robotics, with the goal of building a fully vertically integrated launch company that can design, manufacture, and launch rockets at a fraction of traditional cost and time. Founded in 2015 by Tim Ellis and Jordan Noone, former SpaceX and Blue Origin engineers, Relativity uses its proprietary Stargate metal 3D printing system — the world's largest metal 3D printer — to fabricate rocket structures from aluminum alloy, reducing part counts from 100,000+ (traditional rockets) to under 1,000.
