Methodology Extension from Stereolithography (SLA) to Selective Laser Melting (SLM)

     An initial study of SLM experimental data demonstrates that our prescriptive modeling methodology can be extended to metal based additive manufacturing processes.
   Based on four simple test shapes, we can predict the in-plane deformation profile of a freeform shape. Below is the predicted deformation (in solid line) comparing with CMM measurement (red dots). This is a joint study with Prof. Colosimo and Prof. Grasso at Politecnico di Milano.

                                      The plot was generated by PhD student Ms. HE Luan at USC.
