South Korean Researchers Validate 3D Printed Titanium Tank Under Space-Like Cryogenic Pressure

South Korean researchers validate 3D printed titanium tank under space-like cryogenic pressure

A consortium led by the Korea Institute of Industrial Technology (KITECH), a state-affiliated applied research center, has completed the world’s first cryogenic proof pressure test of a laser-wire 3D

South Korean researchers additively manufacture spherical high-pressure tank capable of passing 330-bar test at -196°C

To satisfy stringent aerospace dimensions and structural requirements, the researchers used AM technology to print two titanium hemispheres, before joining them together through a sequence of heat treatment, precision machining and welding.
