An innovative new single step process for printing synthetic human skin could offer a significant step forward in skin graft procedures.
The process, from a team at Pohang University, relies on a hybrid printing system, in which the printer head extrusion and inkjet modules are used at the same time. As the extrusion module creates the collagen-based scaffold, the inkjet system evenly distributes the keratinocytes (the main cell in the skin outer layer) on the structure.
According to the team, the printed skin displayed promising biological characteristics, including a layered structure and excellent stretching abilities.
