Agnikul: First To Fire A Fully 3D Printed Rocket Engine

Rocket engines are tough to build and are so powerful to construct,
And they’re even tougher to 3D print because all the details have to be ‘just right’ for the rocket to work successfully
But, an Indian space startup based out of Chennai has pulled off this mammothian task ,Indian space startup Agnikul Cosmos has become the world’s first company to successfully test a fully 3D printed rocket engine
Agnikul Cosmos has successfully fired its higher stage semi-cryogenic rocket engine called Agnilet. This is a unique rocket engine because it is completely 3D printed, as a single component, in one run of a 3D printer ,This entire engine, Agnilet, is just one piece of hardware from start to finish and has zero assembled parts,
Normally, rocket engines have 100s of different parts that have to be built individually. This includes things like injectors which inject fuel into the engine, cooling channels that ensure the engine doesn’t overheat and the igniter which actually kindles propellants to push the rocket off the ground
Agnilet, is a three-in-one solution, It takes all three of these modules and puts them into a single piece of hardware
The rocket engine is capable of carrying upto 100 kilos to low earth orbit which is around 700 kilometers above the Earth’s surface. That’s only a fraction of what the Polar Satellite Launch Vehicle is capable of and possibly only enough to carry a single satellite at most
Agnikul may be the first to be successful, but it’s not alone
Agnikul was the first Indian space startup, to enter into a non disclosure agreement , with the Department of Space,, under the newly established Indian National Space Promotion , and Authorisation Centre , in space
Another space startup is Hyderabad-based Skyroot Aerospace , they too revealed their fully 3D printer cryogenic rocket engine dubbed Dhawan 1
The only US based startup , close to producing a fully 3D printed rocket engine is , Firehawk Aerospace, and they only just raised ,the $2 million , needed to start on their project
The global space industry is expected to generate $ trillion or more by 2040, According to Morgan Stanley ,more than triple its current value of $350 billion, And, new space engine technology like 3D printed rocket engines are expected to play a big role in this explosion of value
