Space exploration comes close to preparing long interplanetary flights. Ensuring the life of astronauts will require non-standard medical equipment. Specialists from the University Hospital of Dresden Technical University have developed an original 3D printer designed to print bones and skin under zero gravity. During a long interplanetary flight, unforeseen unusual situations can occur, as a result of which astronauts will get burns or fractures. Recovery will be carried out independently in zero gravity. The best solution may be the transplantation of 3D-printed skin or bone material. Traditional transplants are less effective, since in space conditions healing is slower, and astronauts will also have secondary damage to places where donor material will be taken from. Space 3D printers use innovative ideas. So developed non-standard \In order for the materials obtained for treatment to retain their properties and effect under microgravity conditions, the researchers supplemented the consumables with plant material and the necessary minerals. While the creation of space printers for printing bones and skin is at the very initial stage of development, scientists still have to solve many more technical problems.
