Artificial skin and preparation method thereof

The invention provides artificial skin and a preparation method thereof. According to the artificial skin disclosed by the invention, xenogeneic cell derma removed substrate particles are used as mainraw materials, a 3D printing technique is adopted, a derma layer is prepared, then a cuticle layer is combined with the derma layer, and the artificial skin is prepared. The derma layer of the artificial skin disclosed by the invention has a three-dimensional porous structure, main components of natural derma substrates are reserved in the composition, the distribution structure of the natural derma substrates in the beam diameter and the bore diameter is simulated in the structure, and the novel bionic derma bracket has obvious advantages in the respects of the functions of inducing migration and regeneration of skin cells, accelerating vascularization, promoting wound healing, improving healing quality and the like. The derma layer of the artificial skin, prepared through the 3D printing technique, is precise i
