Using 3D printing technology combined with chemical and high simulation biomaterials to provide two kinds of simulation organs. A simulated organ 1adefg has the advantages of highly personalized size, shape and vascular positioning, soft material manufacturing, mechanical properties such as hardness and elasticity, highly personalized color, adjustable transparency, fast processing speed and low cost. Another kind of simulated organ 1BC is to print the simulated organ with high simulated biomaterial, which not only inherits the advantages of the former organ, but also gives doctors a high sense of close to the real organ when simulating elasticity, hardness and surgery. In addition, the model can be identified by B-ultrasound, which can not be realized by other models.
