Company Overview:

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Meeting the needs of a growing demand for space infrastructure, our rockets will revolutionize how we connect and communicate on Earth by getting satellites to space. We have developed a vertically integrated technology platform in which we leverage additive manufacturing, artificial intelligence, and autonomous robotics to 3D print rockets. Our unique approach enables rapid product iteration, allowing us to push the boundaries of what's possible today and unlock the full potential of 3D printing for tomorrow. Join us on this extraordinary journey, as we work together to transform our vision into reality.


The Weld Development team at Relativity Space is responsible for all post-additive welding operations. Our mission is to ensure the proper processes are developed, sustainable tools are built, and designs are created that support the manufacturing of the next generation of 3D printed rockets – Terran R through implementing creative solutions to previously unsolved challenges and challenging the status-quo on the stale evolution of traditional rocket manufacturing.
