Printable human skin analogues have a number of important real-world uses, particularly as current replacements for animal models used in testing things like cosmetics.
Via ITRI Taiwan:
ITRI's cell culture team developed a new human skin equivalent 3D printing technology to meet the needs of bionic skin production. The technology has been implemented in a 3D bio-printer and setup in a biological safety cabinet. With the 3D bio-printer, the bioink can be used to print a 3D skin structure easily in the multiwell (1-to-24 well) cell culture plates.
