A Comparative Analysis of Laser Additive Manufacturing of High Layer Thickness Pure Ti and Inconel 718 Alloy Materials Using Finite Element Method

Investigation of the selective laser melting (SLM) process, using finite element method, to understand influences power and scanning speed on heat flow melt-pool dimensions is a challenging task. Most existing studies are focused study thin layer thickness comparative same materials under different manufacturing conditions. The present work analysis thermal cycles complex behavior high multi-layer additive (LAM) pure Titanium (Ti) Inconel 718. A transient 3D finite-element model developed perform quantitative two examine temperature distribution disparities in behaviours similar processing It observed that layers properly melted sintered for considered process parameters. increases as move when new added. increases, opposite increasing while keeping other parameters constant. also found 718 alloy has higher maximum than Ti material parameter hence dimensions.
