The 3D rocket-printing company Relativity announced its second partnership ever, this time with the Thai satellite company mu Space, to launch a satellite into low Earth orbit in about three years.

Los Angeles-based Relativity is a small launch vehicle developer fully funded by venture capital. Investors backing the 3.5-year-old company includes Playground Global, Y Combinator, Social Capital, Mark Cuban and Phillip Spector, who was formerly with Intelsat.

The mu Space satellite would launch in 2022 on what Relativity officials call the first 3D-printed rocket ever built. According to them, this vehicle — Terran 1 — is designed to carry up to 2,756 lbs. (1,250 kilograms) into low Earth orbit, with a cost of $10 million per launch.

Relativity officials say their Stargate machine is the largest metal 3D printer in the world, with the capacity to transform raw materials into a rocket, like Terran 1, in less than 60 days.

"Stargate is constantly getting smarter and faster by using sensors and reward function-based learning,'' officials state on Relativity's website. ''We are creating an entirely new type of evolvable production line.'' The company aims to disrupt decades of global aerospace manufacturing, according to their recent announcement about the new partnership.

Relativity signed its first contract earlier this month , with the Canadian satellite communications company Telesat.

This is just the beginning of Relativity's ambitions. While currently striving to deploy and resupply satellite constellations into orbit around Earth, Relativity is also making bold statements about its future. By scaling rockets quickly, company officials hope to ''build the future of humanity in space,'' according to the website . ''We believe the future of humanity is interplanetary.''
