Abstract
Powder bed fusion process is one of the basic technique associated with additive manufacturing. It follows the basic principle of manufacturing the product layer by layer and their fusion. A heat source focuses its heat over a powder base material and heats the selected cross section area. Sources like laser beam, electron beam and infrared beam are used as heating tool. The process of heating allows the powder to take the shape of the intended object. Powder bed fusion process is compatible to every engineering material such as metals, ceramics polymers, composites etc. this technique is widely used in many industrial sectors such as aerospace, energy sector, transportation etc. A comprehensive overview on powder bed fusion process is presented in this review paper. Other popular techniques like selective laser melting (SLM), selective laser sintering (SLS), and electron beam melting (EBM) are also reviewed.
