Investigation into the Differences Thermal Properties of SLS Polymer Powder Materials Using Differential Scanning Calorimetry (DSC)

Abstract:

In order to produce good functional Laser Sintering (LS) parts, it is important that the powder on the part bed surface receives a sufficient amount of power energy through the laser sintering process. The reason is that sufficient energy density is produced when the energy input increases and is applied to the part bed surface, which causes a higher temperature, and thus better melt flow. The objective of this research is to investigate the thermal properties of polymer materials used in Selective Laser Sintering (SLS) processes. In this experiment, there were five different thermoplastics powders known as polyamide 12 (PA2200), Glass Fill Polyamide (GF3200), Alumide, Duraflex and CastForm were tested using Differential Scanning Calorimetry (DSC). This outcome of this research would assist the SLS users to improve the sintering process and quality of the part surface finish.
