'In' human bones with 3D technology

Scientists at Washington University in the US have used a three-dimensional printer to ' bone ' the shape of a natural bone, which can be used to treat injuries.

Artificial pelvis is made from calcium-phosphate powder, which can be implanted into the body's natural bones. It works as a temporary framework for several years while waiting for new bone cells to grow and then decompose without affecting health.

To create bone, scientists use 3D printers. This printer can produce any bones in the body. The printer uses a thin plastic adhesive coating that covers the surface of the calcium carbonate powder. This process is repeated until the bone is complete. The product is then dried, cleaned and baked for 2 hours at 1250 ° C.

"It's mostly suitable for less pressure-bearing positions in the body," said Susmita Bose, co-author of the report in the journal Dental Materials. To double the strength of calcium-phosphate, scientists added silicon and zinc oxide.

The researchers said they received promising results in rabbits and mice.
