3D-Metal Printing Technologies: Comparative Study of the ‘Electron Beam Melting’ and ‘Selective Laser Sintering’

Abstract

3D-printing is an innovative manufacturing methodology. In this 3D-models can be set up using computer
aided solid models. Those are digital files. A part is created in this method by establishing layers of
material one over the other until the total part is formed. These layers can be thought of as a thin material
slice. These methods are widely used in life-sciences, footwear, aerospace, automobile, jewelers and
biomedical engineering. ‘Stereo-lithography’, ‘FDM’, ‘SLS’, and ‘EBM’ are different forms of printing
techniques. Through these 3D-printing methodologies complex shaped parts can also be device with
increased correctness. This paper explains the comparative study of electron beam melting with selectivelaser-melting.
