The skin is the body's first line of defence, and its physiology is complex. When injury occurs, the skin goes through a complex recovery process, and there is the risk of developing a chronic wound. Therefore, proper wound care is critical during the healing process. In response to clinical needs, wound dressings have been developed. There are several types of wound dressings available for wound healing, but there are still many issues to overcome. With its high controllability and resolution, three-dimensional (3D) printing technology is widely regarded as the technology of the next global industrial and manufacturing revolution, and it is a key driving force in the development of wound dressings. Here, we briefly introduce the wound healing mechanism, organize the history and the main technologies of 3D bioprinting, and discuss the application as well as the future direction of development of 3D bioprinting technology in the field of wound dressings.
Keywords: 3D bioprinting; chronic wounds; skin tissue engineering; wound dressing; wound healing.
