So those kids over at NASA have been pretty busy. This time taking 3D printing even further, NASA has announced they’ve successfully tested a rocket engine fuel injector made using the new technology.
By using a specific technique called selective laser melting (SLM), they were able to cut the manufacturing time down from one year to four months, and reduce the cost by over 70%.
“Nasa recognises 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” – Michael Gazar
The term “additive manufacturing” refers to building a product from the ground up using the specific materials and quantities needed. On top of the benefits stated above, this technology also drastically reduces the amount of waste by-product.
