Predicting processing parameters in high temperature laser sintering (HT-LS) from powder properties [PDF]
Materials & Design, 2016 Abstract New materials for laser sintering (LS) are usually developed using a trial and-error approach that consists of a series of builds within LS systems. This strategy is time consuming, costly and focuses only on the optimisation of the processing parameters, ignoring the powder properties of the materials under examination.
