Additive Manufacturing of Metals: A Review | Original Article
Additive manufacturing technology is making the buzz and is said to entirely change the perspective of how manufacturing will be thought of. Initially used only for prototyping, now AM products can be used as end user items. But for engineering industry, metallic parts still play a huge role and versatility of any technology unable to create metal objects would be severely restricted. So researchers are working to develop technology that is able to create metal parts by additive manufacturing. But cost, cycle time and quality of such parts still pose a challenge for researchers. This paper reviews the technology for metal additive manufacturing in broad sense and is based on various criteria such as materials, raw material form, energy sources etc.
