  • The objective of this paper is to investigate into the development of injection mould with high cooling characteristics using a direct metal RP technology. In order to manufacture the injection mould with a high cooling rate, three-dimensional conformal cooling channels have been generated in the mould. DMT process, which is one of direct metal RP technologies, has been utilized to directly manufacture the metallic mould with three-dimensional conformal cooling channels. In order to examine the performance of the designed mould, injection molding tests have been carried out. The results of the experiments have been shown that a cooling time and the injection time of the proposed mould are reduced by the factor of five and two times in comparison with the injection mould with linear cooling channels.
