英文摘要：

For the problem of complex surface prototype model making thin-walled parts,the three commonly used method of making the opponent plate and model were compared to study the key technology of rapid prototyping process, including： STL file format conversion formatting parameters and rapid prototyping key parameters set on the key issues of ordinary model, prototype thin-walled parts of complex surface models were discussed and compared. By curved wall thickness 0.5 mm part design and model making, ordinary parts and surfaces suitable for thin-walled parts rapid prototyping parts reasonable parameters were proposed. The results show that, as long as the proper selection of critical process parameters reasonably avoid surface thin wall fracture parts prone to rapid prototyping,multi glitch problems efficiently manufacture high-precision model, to meet the needs of the characteristic model.
