The wound especially the skin wound healing is the commonest problem faced by surgeons. Several technologies have become available for skin tissue engineering that adopts a fundamentally different and novel approach recently. Among these, the applications of 3D bio-printing opened a new way to heal wound. There were four parts in this review. First, we introduced the concept of 3D bio-printing briefly. The main 3D bio-printing technique included ink-jet printers and Laser associated 3D printer. Second, we summarized systematically extra cellular matrix being the basic scaffold of 3D bio-printing. Thirdly, the application of 3D bio-printing in both in vitro and in vivo artificial skin tissue was introduced. At last, we outlook the future of application of 3D bio-printing in wound healing.

Keywords: 3D bio-printing, skin, wound healing.
