This general review paper compares two powder-bed fusion metallic additive manufacturing processes. The method is by reviewing past literature from sources such as scientific databases, journals, conferences and webpages. The scope of this review is on the selective laser melting and electron beam melting additive manufacturing method. The findings have shown large advances in the manufacturing quality of these two methods commercially. This review thus facilitates the choice of using either a laser based or electron based method for a given application.
