The reconstruction of three-dimensional model algorithm STEP- based in rapid prototyping technology

The current most STL(stereo lithography)format is widely used as a de facto industry standard in the rapid prototyping industry due to its simplicity and ability to tessellation of almost all surfaces, but some drawbacks such as precision loss, data redundancy and not conducive to concurrent design and the limitations of network synergy lead to unsatisfactory precision of the part in post processing. In order to reduce the above problems, a new processing module of STEP-based neutral exchange of AP203 file data of 3D reconstruction is designed and implication in this paper. Using a dynamic linked list as a data storage structure and dynamically allocating storage space, we successful extracted the information of the neutral file model of geometry and topology. The experiment shows that the speed of reconstruction and display rate were increased.
