Injuries are a highly likely occurrence in space, but given the conditions, providing first aid to astronauts is a true challenge. Researchers from Dresden Technical University have come up with a solution to the problem.
Astronauts’ bones and muscles conditioned to the earth gravity begin to weaken in weightlessness and this may cause fractures and other injuries. The researchers believe that 3D bio printing can resolve the issue. This technology is currently used on the ground, helping to heal wounds or even print some organs.
Ink for such printers will be made from the astronauts’ plasma, blood and stem cells. If a crew member is injured, the team will be able to print a healthy bone or a piece of skin.
The mixture will also contain methylcellulose and alginate - the substances that will give the liquid bio inks the viscosity they need in microgravity. The printers will be able to function even upside down.
