Abstract:

Today, polymer materials have a wide range of use, from household items to engineering applications. Therefore, it is important to develop its characteristics. Additional additives can increase the characteristics of polymer materials. Additional technique and compositions can vary according to the manufacturing method. It is a new method of production and it is possible to use additives in the production method of selective laser synthesis (SLS), which is based on the synthesis of infrared laser rays and polymer powder. Although the use of additives in this method is not very common, the most preferred additives are ceramic-based inorganic materials. However, thin metal particles can also be used as additives. In this study, the process with SLS of polyamide 12 contributed to dendritic copper powder was studied. Two different additives contained in powder mixtures have been characterized in order to determine the process parameters and it has been found that increased energy intensity should be used. As a result of the physical and mechanical tests of the samples produced using five different parameters, the inclination characteristics and dimensional sensitivity decrease, the surface smoothness has not changed and the storage module has shown improvement.
