A joint research team at the Korea Institute of Industrial Technology (KITECH) became the first in the world to pass a cryogenic pressure test on a large 130-liter titanium high-pressure vessel produced with directed energy deposition (DED) 3D printing. The vessel withstood a proof pressure of 330 bar in liquid nitrogen at minus 196 degrees Celsius. This showed that it is reliable under the conditions it would face in actual space operations. The achievement is significant because it lays a foundation for overcoming the material supply problems and design constraints of conventional casting and forging methods, and for reducing manufacturing costs. Additive manufacturing technology is expected to be widely used in a range of aerospace applications, including space launch vehicles and satellites.
