The latest printing technology–3D printing–has gone out of this world. NASA will soon take printing to a whole new level. On Sept. 23, the first 3D printer arrived at the the International Space Station (ISS) aboard SpaceX’s unmanned Dragon capsule. .
3D printing is the process of building an object, layer by layer, out of many different types of material including metal, plastic, and composite material. There are high hopes that this new printing technology will expand the station’s manufacturing capabilities. Although having replacement parts sent to the ISS is costly and time consuming, this new capability is expected to decrease resupply efforts from Earth while cutting costs by creating the possibility of fixing station issues with just a switch of a button.
