Engineers pioneer use of 3D printer to create new bones

custom-built bone scaffolds within the next few years

A 3D printer is being used to create “bone-like” material which researchers claim can be used to repair injuries.

The engineers say the substance can be added to damaged natural bone where it acts as a scaffold for new cells to grow.

It ultimately dissolves with “no apparent ill-effects”, the team adds.

The researchers say doctors should be able to use the process to custom-order replacement bone tissue in a few years time.
