Othisis hot-fires 3D-printed cryogenic rocket engine prototype
TL;DR. Indian startup Othisis successfully hot-fired its fully cryogenic 3D-printed rocket engine prototype after two years of development. - The 5 kN engine uses Selective Laser Melting (SLM) 3D printing for its construction. - This prototype will power a planned reusable hopper rocket later this year. - The achievement demonstrates rapid advanced manufacturing capabilities for space propulsion.
