Advances in the research of three-dimensional skin printing / 中华烧伤杂志

As a new technology, three-dimensional printing possesses the characteristics of high precision and strong controllability, which has become a new technology and can be used in tissue engineering. Currently, using three-dimensional printing to build artificial skin has made certain achievement, and experiments in vitro have confirmed that the three-dimensional printing has the possibilities to build artificial skin whose structure and function are close to those of nature skin. However, the technology is not yet very mature and there are still some problems need to be solved, such as the recreation of the cutaneous appendages and the degradation and absorption of the extracellular matrix.
