Believe that everyone knows good castings is to have professional technology to carry on the processing production, and also to control the casting of before and after treatment to complete the production, in the process of the casting way of rapid prototyping about the quality of the castings have what kind of impact?Rapid prototyping control of the deformation of precision casting, by changing the process parameters, scanning mode, and even sub-regional scanning effect is not significant, fundamentally to control deformation by reducing resin shrinkage rate to achieve, but zero shrinkage of resin can be difficult to achieve, usually by optimization model of production direction, to add auxiliary support balance shrinkage stress method to eliminate the buckling deformation in the process of stamping production.Parts deformation usually occur in parts of regions of the cantilever, the bottom of foundation, the paper called the deformation surface, by optimizing the production direction, make it prone to deformation of the prototyping of the smallest, can effectively eliminate the shrinkage deformation of fabrication in the process of production.Can also be in the process of production, to product areas prone to deformation of cantilever, the bottom of foundation support, can be constraints caused by shrinkage deformation, improve the forming precision of the parts.
