Thermal properties of polymer materials in laser sintering process

The objective of this research is to study the thermophysical properties of polymer materials used in Selective Laser Sintering (SLS). There are seven virgin SLS materials which are PA, GF, Alumide, PrimeCast, PrimePart DC, Duraflex and CastForm. Differential Scanning Calorimetry (DSC) was used in f...
