Indian Startup Unveils World's Largest 3D-Printed Rocket Engine
Imagine building a super strong rocket engine, but instead of putting it together piece by piece, you print it all at once using a giant 3D printer.
That's what an Indian company called Agnikul Cosmos has done!
They made the biggest rocket engine ever printed as a single piece, and they even got a patent in the US for it.
This new engine is made of a special metal and is super strong without any welding.
They also made a new engine that uses electric motors, making it more efficient and easier to control.
This is a big step forward for India's space program, and shows how private companies are helping to explore space!
Agnikul Cosmos developed the world's largest single-piece 3D-printed rocket engine.
The engine is made from inconel and printed as a single component without welds or joints.
Agnikul Cosmos secured a US patent for the engine's design and manufacturing process.
The startup also successfully test-fired India’s first electric motor-driven semi-cryogenic rocket engine.
The advancements highlight the growing innovation in India's private space sector.
