a Simulation results on SLS processing of SS316L powder bed with P0 = 20 W and v = 100 mm/s. Overheat region where T ≥ TM is noted with continuous colormap while one with T < TM is noted with isotherms; b phenomena and characteristics around the laser beam spot during the process. Comparison of the surface morphology between the simulated and experimental results in the case of c P0 = 5 W, v = 20 mm/s and d P0 = 5 W, v = 5 mm/s.
