| General note | The additive manufacturing technology Selective laser melting (SLM) also referred as<br/>laser powder bed fusion (LPBF) is a technique that can produce intricate metallic parts in<br/>3D. However, maintaining an accurate surface finish and shape can be difficult because<br/>of the dynamic thermal cycles of melting and solidification. To produce high-quality<br/>products, it is essential to maintain the dynamic stability of melt pool in SLM. This<br/>requires studying the temperature distribution and thermal behaviour within the pool. In<br/>this study, a Finite Element Modelling (FEM) approach that was experimentally verified<br/>was utilized to precisely ascertain the thermal profiles and dimensions of the molten pool.<br/>To investigate the impact of different process variables on the shape of the pool during<br/>the selective laser melting (SLM) of SS316L powder, a transient model was employed. A<br/>FEM model was proposed to evaluate the temperature gradient and characteristics of the<br/>molten pool during SLM, with laser penetration depth also taken into account. The<br/>proposed heat source model was calibrated with data from the literature. The FEM model<br/>was subsequently adjusted and validated through further experimentation to ensure that it<br/>accurately predicts the melt pool dimensions and temperature profiles. The model findings<br/>were consistent with the experimental data, and the effects of interlayer and intertrack<br/>were examined. For each layer and track, the molten pool depth, width, and length of the<br/>and the temperature distribution were assessed, and the findings were analyzed for each<br/>variable. The FEM model had relative errors of 1.88%, 1.49%, and 2.12% for the<br/>predicted melt pool length, width, and depth, respectively, compared to the experimental<br/>measurements, for a range of optimal parameters. |
