Chennai-based space tech startup Agnikul Cosmos, which is developing India's first private small satellite launch vehicle, became the first company in the world to successfully test a fully three dimensional (3D) rocket engine. Agnikul Cosmos has successfully test-fired its higher stage semi-cryogenic rocket engine, Agnilet.

Srinath Ravichandran, CEO and co-founder of Agnikul Cosmos, said, “This entire engine – Agnilet – is just one piece of hardware from start to finish and has zero assembled parts. We don’t think anyone in the world has ever pushed 3d printing of a rocket engine to this extent and we couldn’t be happier to have conceived, designed, realized and test-fired this engine, fully in India.”

Usually, rocket engines gave 100s of parts in them but Agnilet was designed in such a way to encapsulate all these parts into just one piece of hardware.

Meanwhile, there are other players in the race. In September last year, Hyderabad-based Skyroot Aerospace revealed their fully 3D printer cryogenic rocket engine, Dhawan-I. The US-based startup, Firehawk Aerospace, is also close to producing a fully 3D printed rocket engine.
