The model should be approximate treated before 3D Rapid Prototyping to facilitate subsequent data processing. Since the STL format file format is simple and practical, it has become the standard interface file in the field of 3D Rapid Prototyping. Each small triangle is described with 3 vertex coordinates and a normal vector, and the size of the triangle can be selected according to the precision requirements.
3D Rapid Prototyping The design and processing information of a new part can be obtained by modifying or reorganizing a CAD model. Parts can be made from a few hours to dozens of hours, with an outstanding feature of rapid manufacturing. The complex manufacturing process can be accomplished without the use of any special fixture or tool, and the tooling, prototype or part of the workpiece is quickly manufactured.
Laser 3D Rapid Prototyping is a new manufacturing technology. Compared with the traditional manufacturing method, it has the following advantages: The prototype has high reproduction and interchangeability, and the manufacturing process has no relation with the geometrical shape of the prototype; short processing cycle, low cost, general manufacturing cost reduced by 50%, the processing cycle is shortened by more than 70%; High technology integration, design and manufacturing integration.
3D Rapid Prototyping for some plastic structure-oriented products can also carry out small-batch trial, or some physical aspects of functional testing, assembly verification, the actual appearance of the effect of the survey, and even product small batch assembly first put into the market, to achieve waters purposes.
