Using the CAD Compensation Factors to Improve the Accuracy of the SLS Parts

The paper presents a complete case study focused on studying the accuracy of a par, startinf from the CAD model, in order to make that part finally by injection molding. The research developed within National Centar of Rapid Prototyping from Technical University of Cluj Napoca and PŠlastor SA company from Oradea focused on the manufacturing the active elements for injection molding tools by selective laser sintering technology, using a metallic dedicated powder, laserform St-100. There were revealed the peculiraities and complexity of this technology, which involve CAD aspects and different issues regarding the part manufacturing accuracy, correlated with the shrinkage phenomena that appears in post processing stage in the oven.
