Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair damaged bone tissue. Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as 'ceramic omnidirectional bioprinting in cell-suspensions' (COBICS), enabling them to print bone-like structures that harden in a matter of minutes when placed in water. While the idea of 3D-printing bone-mimicking structures is not new, this is the first time such material can be created at room temperature – complete with living cells – and without harsh chemicals or radiation, says Dr Iman Roohani from UNSW’s School of Chemistry. “This is a unique technology that can produce structures that closely mimic bone tissue,” he says. “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…
