Abstract
Additive manufacturing process of joining materials to make object 3D model data, usually layer upon layer, as opposed to subtractive manufacturing technologies. There are so many challenges in the AM process like process control, surface finish, tolerance, validation .Selective laser melting process starts by numerically slicing 3D CAD model in to number of finite layers. The process of selective laser melting involves the moving of a laser beam across a powder bed to melt material type layer by layer, from the stand point of modelling. This process is complicated as it is characterized by high temperature gradients caused in non equilibrium, conditions during solidification. This causes various effects on microstructure features properties, dimensional accuracy, and surface finish. The material properties such as yield strength, elongation, ductility are highly affected by the microstructure features. Additives manufacturing process are extensively used in automotive, aero space, bio medical, industries. For selecting laser melting process is most significant joining process in the automobile industries due to high speed and suitable for complex geometries. Strength, hardness and micro structure and surface finish of AM parts are focus of the researchers since last two decades. To get better components that can be used as full functional parts with better process control with full density with various types conventional and new developed materials is the need of modern age.

Keywords- additive manufacturing process, selective laser melting, process parameters numerical modelling, simulation
