In Germany, researchers are testing whether 3D-printed skin cells could work for wound care on long space voyages. The German Space Agency’s Bioprint FirstAid Handheld Bioprinter combines astronaut cells and biobased ink to create a plaster-like covering that can be applied directly to wounds.
The device, which is small and manual, was included on an International Space Station resupply run late last year. However, this particular test does not include actual skin cells, but is meant to evaluate the viability of 3D printing in space.
There are earthly applications for the Bioprint FirstAid Handheld Bioprinter as well. Using a patient’s own skin to patch wounds on earth would reduce the potential for immune system rejection, and the portable device could be used for would care in non-hospital settings.
