3D printing is a technology used to print three-dimensional objects using a specially designed 3D printer. The technology has seen numerous developments, advancements and applications since its inception. It has been one of the most talked about developments in the digital world and has involved millions of investment and funding in R&D establishments by big commercial and defence players around the globe enabling creation of almost everything from tiny human body parts to construction of buildings today. However, the most challenging aspect involved in the 3d printed objects is the reliability factor that will impact the future of this technology. This article aims at study of the 3D printing technology and recommend the way forward for its utility in improving on-site engineering support as the function of Corps of EME.
