A new innovation allows scientists to 3D-print human bones from a person's own living cells and for the first time, the process has been done at room temperature.

A team at Australia's University of New South Wales-Sydney created a 'bio-ink' gel that contains a patient's live bone cells in a calcium phosphate solution, which are necessary minerals for bone formation and maintenance.

Using a technique known as ceramic omnidirectional bioprinting in cell-suspensions (COBICS), the gel is 3D-printed directly into the patient's bone cavity instead of surgeons having to remove a piece from a different location.

The material then hardens within minutes of being exposed to bodily fluids and converts into mechanically interlocking bone nanocrystals.

The act of 3D-printing bone-mimicking structures is not new, but the University of New South Wales-Sydney's method allows the process to be done at room temperature for the first time.

This means bones can be created on the spot inside a medical room, along with using the patient's own living cells.

Dr Iman Roohani from UNSW's School of Chemistry, jasa Konten sosial media, Winstarlink.com, said: 'This is a unique technology that can produce structures that closely mimic bone tissue.'

'It could be used in clinical applications where there is a large demand for in situ repair of bone defects such as those caused by trauma, cancer, or where a big chunk of tissue is resected.'
