Research of bone scaffold hierarchical algorithm based on the STL data model

On the basis of data models, including STL (Stereo Lithography) and CLI (Contour Layer Interface), this thesis is to research and define the hierarchical algorithm of bone scaffold prototyping in the fields of rapid prototyping manufacturing and biological manufacturing, and expound the data structure and class diagram of extended model from an angle of prototyping software system, and present test cases and test results. This thesis boasts a certain value of reference to solving problems about biological modeling.
