Additive manufacturing technology (AMT) popularly recognized as 3D printing is a disruptive technology that has the potential to change many conventional or subtractive manufacturing methods such as drilling, forging and machining. The technology is capable of joining some materials and creating objects from 3D computer-aided-design (CAD) model data, usually layer-upon-layer in distinction to traditional subtractive manufacturing technologies. Among others, there are popular techniques, such as stereolithography (SLA), fused deposition modelling (FDM), powder bed fusion and inkjet 3D printing (3DP), which are employed broadly in low quantity components production for more than a few applications. Additive manufacturing gives many strategic advantages, inclusive of extended design freedom for constructing complex internal and external section geometries that cannot be made in any other way, and the potential to repair expensive components for aerospace, clinical and many different industries. In this work, an overview of additive manufacturing processes and their impact on industrial practice is provided. Discussions are on some of the medical, automobile and aerospace applications of AMT and the usage of the SWOT analysis, describing the strengths, weaknesses, opportunities and threats dealing with AMT applications. Manufacturers, therefore, can adopt this technology for standardization of quality manufacturing practices in our country.
