INNOVATIVE SOLUTION TO DECREASE THE POROSITY OF INJECTION MOULDING TOOLS MADE BY SELECTIVE LASER SINTERING TECHNOLOGY

Razvan Pacurar, Ancuta Pacurar

Abstract


The manufacturing of the injection moulding tools is one of the most important industrial applications of Selective Laser Sintering (SLS) technology. The resulted porosity after post-processing stage in the oven has an important influence on the mechanical properties of the SLS metallic parts. In order to reduce the porosity, a new post-processing method has been developed as compared to the classical one. The paper presents the new method and some results obtained by the authors.
