Numerical simulation of heat transfer in the selective laser sintering process of Polyamide12

Selective laser sintering (SLS) process is the most perfect seven three-dimensional printing processes that produces three-dimensional parts from a polyamide or metal powders in stratified, the need of this process is in all different fields, the medical field, art, aerospace and other industries.
