Scientists have reportedly produced a metal 3D printing machine which can be used in space.
Scientists have reportedly produced a metal 3D printing machine which can be used in space.

Wang Lianfeng, a senior engineer with the China Aerospace Science and Technology Corporation (CASTC) told China news agency Xinhua that the machine could make items out of stainless steel, titanium alloy and nickel-based superalloy.

It would be used to print optical lens brackets used in spaceborne equipment, components used in nuclear power testing equipment, impellers used in aircraft research and special-shaped gears used in automobile engines.

The machine, which uses both long-wave fiber and short-wave carbon dioxide lasers, can produce items smaller than 250 millimeters.

"The products made will have to be tested thoroughly, due to the strict quality requirements of aerospace products," said Wang.
