3D printer reproduces human tissues and bones

• April 26, 2024

Researchers headed by the professor James Yoo, from the Institute of Regenerative Medicine at Wake Forest University , and for the Cornell University , they developed a printer that could reproduce human tissue, cellular structures and possibly even complete organs.

According to the BBC , this bio printer employs a laser scanner that analyzes the area and depth of a wound, data that is translated into a 3D digital image to calculate the number of layers of skin cells that need to be printed to restore the original condition of the tissue.

For the time being, several silicone tests have been carried out, however, according to the professor Hood Lipson, from the Computational Synthesis Laboratory , have made various tests on silicone and will soon try to print heart valves.

Therefore, it stands as an alternative for patients who suffered some injury, traumatism or Burns and that require treatment and new skin grafts, or other organs.

However, it is not the only application of this type of 3d printers , since the teacher Susmita Bose, from the University of Washington , leads a study in which molded ceramic powder is used by a printer to generate woven bone .

According to the researchers, this substance can be added to damaged natural bone and act as a scaffold to grow new cells, which could produce material osseous according to the measures that are required to repair various injuries .

The bone damaged is reproduced in its original form by printing successive layers until they are completed, at which time the scaffold is dried, cleaned and then baked for two hours at 1250 ° C. thereby replacing the bone without apparent secondary damage.
