#科技头条#【NASA将在太空中使用3D打印】据悉,NASA目前正在使用3D打印技术制造飞船及一些设备的部件,并且在不久后,宇航员或许将在太空中直接使用3D打印制造工具或替换的部件。也许,未来NASA将出现这样的对话:“明天就要出发了,火箭呢?”“在我U盘里,马上去打印。”

NASA

 

The newest adopter of 3D printing isn't some hobbyist in a basement — it's NASA.

The agency is already building some of its customized spacecraft and instrument parts using 3D printing, and someday soon, astronauts might even make tools and replacement by 3D printing them in space.

NASA's Space Technology Mission Directorate has launched several programs to create prototypes of tools for current or future missions using 3D printing, or additive manufacturing, a manufacturing technique that uses Computer-Aided Design (CAD) models to build objects layer-by-layer out of plastic, metal or other materials.

"With additive manufacturing, we have an opportunity to push the envelope on how this technology might be used in zero gravity — how we might ultimately manufacture in space." LaNetra Tate, the advanced-manufacturing principal investigator for the directorate's Game Changing Development Program said in a statement.

NASA's Goddard Spaceflight Center in Greenbelt, Md., has already flown a 3D printed battery case on a sounding-rocket mission test, and Marshall Space Flight Center in Huntsville, Ala., used 3D-printed components for the J-2X and RS-25 rocket engines. Marshall is also working with the Silicon Valley start-up Made In Space, which plans to fly a 3D printer to the International Space Station in October.

"We're not driving the additive manufacturing train, industry is," Ted Swanson, the assistant chief for technology for the Mechanical Systems Division at Goddard said in a statement. "But NASA has the ability to get on-board to leverage it for our unique needs."
