My husband pointed out this cool story about how NASA is using 3-D printing. I have had a couple posts about using 3-D to create food, but this is the first use of the technology that really makes sense to me. It’s sending design instructions to someone you have no physical access to so they can create a needed tool.
Janet Fang writes at IFLScience, “For the first time ever, hardware designed on the ground has been emailed to space to meet the needs of an astronaut. From a computer in California, Mike Chen of Made In Space and colleagues just 3D-printed a ratcheting socket wrench on the International Space Station. ‘We had overheard ISS Commander Barry Wilmore (who goes by “Butch”) mention over the radio that he needed one,’ Chen wrote in Medium [in December]. So they designed one and sent it up.
“ ‘The socket wrench we just manufactured is the first object we designed on the ground and sent digitally to space, on the fly,’ he adds. It’s a lot faster to send data wirelessly on demand than to wait for a physical object to arrive via rockets, which can take months or even years.
“The team started by designing the tool on a computer, then converting it into a 3D-printer-ready format. That’s then sent to NASA, which transmits the wrench to the space station. Once the code is received by the 3D printer, the wrench is manufactured: Plastic filament is heated and extruded layer by layer. The ISS tweeted this photo earlier this week, and you can see more pictures of the very cool wrench-printing process here.” More here.
