3D printer successfully makes little space shuttle models in microgravity

Scientists from the University of California, Berkeley, have successfully tested a microgravity 3D printer called SpaceCAL during the Virgin Galactic 07 mission. The printer produced space shuttle models and small tugboats in microgravity conditions using a liquid plastic called PEGDA. This technology, funded by NASA, Berkeley Engineering, and the Berkeley Space Center, aims to validate 3D printing readiness for space travel. The printer, based on computed axial lithography, can create intricate parts in as little as 20 seconds and has demonstrated versatility in printing with over 60 different materials. The ability of SpaceCAL to operate effectively in microgravity environments makes it promising for space exploration applications, potentially enabling astronauts to produce building materials, tools, medical equipment, spare parts, and even replacement organs or tissue. The long-term goal includes printing organs in space and bringing them back to Earth. These advancements in 3D printing technology have the potential to benefit both space missions and people on Earth.
