'3D printed bones' made from blood for use in space
A project to create artificial bone based on astronaut's plasma is underway in outer space where the material used as a material is limited.

3D-printed bone for emergency medicine in space
On April 8, 2022, the European Space Agency (ESA) disclosed a sample of '3D printed bone' created based on plasma, and announced that 'it may be put to practical use on the earth soon'. Did.
It is known that bone mass is significantly reduced compared to when on the ground because the stimulation to bone is reduced in outer space, which is weightless. Astronauts also have a high risk of fractures due to decreased bone density.
In preparation for emergency medical care in the event of an astronaut's fracture in outer space, ESA is developing a technology to print bones in 3D using plasma that can be collected from human blood as bio-ink. In addition to disclosing the sample this time, ESA has shown the possibility that astronauts can make similar bones in outer space.
ESA has positioned this sample as 'an early step in making 3D bioprinting a practical tool that can be used for emergency medical care in space,' and in addition to developing artificial bone, 3D printing artificial skin and organs. He said that he was aiming to develop the technology to do.
