2、inary research area which aims at producing complex organ or tissue, bio-manufacturing is a new trend combining manufacturing science and life science. Started from the application requirements of bio-manufacturing and

3、 employing images reverse theory and 3D dataset reconstruction methods, this paper proceeds theoretical and methodological research on modelling heterogeneous bio-tissues and the key issues of manufacturing the three-

4、dimensional heterogeneous model using rapid prototyping. The creative contributions may be summarized as follows: (1) On the basis of deep study in the advantages and disadvantages of the surface rendering and volume re

5、ndering, utilizing volume rendering algorithm in the modelling 3D heterogeneous bio-tissues is proposed. In order to express the attributes texture, shape and characteristics and the level of relations of the organ or ti
