Novel ink to 3D print'bone' with living cells

摘要

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,said Dr Iman Roohani from UNSW's SchooL of Chemistry.
