A Review- Modelling Approach and Numerical Analysis of Additive Manufacturing

Abstract

Additive manufacturing creates 3-dimensional objects by depositing materials layer by layer. Different applications of additive manufacturing were examined to determine future growth possibilities. The current research seeks to discover existing additive manufacturing techniques based on the process mechanisms, evaluate modelling approaches based on modelling methodologies, and identify required studies. A significant number of numerical simulations are conducted to evaluate the thermal FE structure in terms of solid and powder material thermo -physical properties and permissible boundary conditions. The transient heat conduction is investigated using thermal analysis with a moving heat source.
