Metallic and plastic powders have been used in additive manufacturing for many years. Unfortunately, in processes such as powder bed fusion, the mechanical properties of the parts are different than using traditional machining methods. Some of the deficits of printed parts are directly attributed to the layer by layer process, where the density of the printed parts is overall lower because of the voids generated between the powder particles. Such voids can be generated by insufficient material and/or melting energy. In the previous years, several parametric studies in 3d printing processes have been performed. At this moment, experimental studies using powders are limited because its complexity. The presented research studied on the different thermal distribution of the powder particles under different arrangements in order to improve their thermal conductivity. Our experiments show that compacting the powder helped to reduce the gradients in temperature under certain temperatures more than 50%.
