TRI-D is a 3D printed metal rocket engine. Students from the Students for the Exploration and Development of Space at [1][2] University of California, San Diego (SEDS at UC San Diego) built the metal rocket engine using a technique previously confined to NASA, using a GPI Prototype and Manufacturing Services printer[1] via the Direct metal laser sintering (DMLS) method.[1] UCSD students were the first group in the world to 3D print a rocket engine of its size, other than NASA as of February 2014.[3] The Tri-D engine cost US$6,800.[1][4][5]
