| Abstract: | Direct selective laser sintering (SLS) technology can be used to produce 3D hard metal functional parts from commercial available
powders. Unlike conventional sintering, it does not require dedicated tools, such as dies. Hence, total production time and
cost can be reduced. The large shape freedom offered by such a process makes the use of, for example, sintered carbides components
viable in domains where they were not applied before. Successful results have been obtained in the production of sintered
carbide or hard metal parts through SLS. The investigation focuses on tungsten carbide–cobalt (WC-Co) powder mixture. This
material is characterised by its high mechanical properties and its high wear resistance and is widely used in the field of
cutting tools. This paper is devoted to the experimental study and the simulation of direct selective laser sintering of WC-Co
hard metal powders. |
