Figure 1

Calculated temperature increase on the surface of polished (SRz = 0.076 μm) AISI 316L during processing for different number of passes (resulting from different hatching distances dh) as a function of time. Material parameters: ηabs = 0.55, ηheat = 0.38, ρ = 8000 kg/m3, \({c}_{p}=500\,{\rm{J}}/({\rm{kg}}\cdot {\rm{K}})\), \(\kappa =3.75\cdot {10}^{-6}\,{{\rm{m}}}^{2}/s\). Process parameters: λ = 1030 nm, EP = 1.4 mJ, db = 500 μm, H = 0.71 J/cm2.
