NASA Successfully Test 3D Printed Rocket Engine Part

NASA has announced that it has successfully tested a 3D printed part for a rocket engine using the SLM method. A computer-designed object is turned into a real part  by using high-powered laser beams that melt and fuse thin layers of metallic powders into the designed shape.

According to NASA an injector component would normally take a year to make but by using this technique, they have been able to cut production time to less than four months and reduce the cost by more than 70 per cent.

Michael Gazarik, Nasa’s associate administrator for space technology said

“NASA recognizes that on Earth and potentially in space, additive manufacturing can be game-changing for new mission opportunities, significantly reducing production time and cost by ‘printing’ tools, engine parts or even entire spacecraft,”
