3D printing keeps coming up again and again, swarming and finding application in every field. And now, it has caught the attention of the engineers at NASA.
NASA is testing 3D printing for making spare parts and engine parts for the Space Launch System (SLS), which is planned to take astronauts to the moon, asteroids and one day to Mars also. With an intention of fabricating tools during space stations, a 3D printer will soon be sent to the International Space Station (ISS).
Here, 3D printing is being accomplished with the additive manufacturing method, where thin layers are added successively to build an object using a digital blueprint. 3D printing is becoming an important method where right from household DIYers and space agencies are adopting this wonderful technique.
