Abstract: In spite of numerous benefits offered by additive manufacturing, their primary applications are limited to prototyping. A number of unresolved issues can be cited, which have curtailed their implementation. Among serious problems faced by AM are poor dimensional and geometric accuracy as well as low surface finish. Henceforth, further expansion and better performance entail an increased understanding of AM systems. A wide range of AM technologies, with variations in accuracy and surface finish is available in the market. Most often, the accuracy of AM machines do not persistently conform to the assertions of manufacturer, and thereby desired accuracy is difficult to attain. The goal of this work is to evaluate different AM processes. The most popular processes: fused deposition modelling (solid-based), stereolithography (liquid-based) and electron beam melting (powder-based) are evaluated. This study has been undertaken to provide engineers and designers with useful information about the expected accuracy from different AM systems.
