Using the favourable characteristics of polyamide-12 ( the most often used material for laser sintering ) as a benchmark , a previously un-sintered thermoplastic elastomer material was identified as being suitable for the LS process , through a combination of information from Differential Scanning Calorimetry ( DSC ) , hot stage microscopy ( HSM ) and knowledge of viscosity data .
