3D printing or rapid prototyping are other terms for additive manufacturing (AM). AM is a technique that involves layering materials to create a three-dimensional object. AM is critical for producing complex geometric objects with high precision. The exponential development of additive manufacturing over the last decade has shown significant potential in cost-effective manufacture of high-quality product. It is difficult to produce superalloys like Inconel 625 using traditional methods, but it is much simpler with AM. Atomic diffusion additive manufacturing (ADAM), a layer-by-layer process for metals based on material extrusion, was recently patented by Markforged. An indirect additive production technique such as ADAM uses a metal powder filament encased inside a plastic binder. The plastic binder is separated after the fabrication of a green part by washing and sintering post-treatments. Fabrication of four separate standard tensile specimens for metal 17-4 PH stainless steel with different process parameters as well as four parts are printed for metal Inconel 625. The tensile test is carried on UTM with these eight parts. As a result, the weight reduction due to infill density is 20%, resulting in a loss of 10–15% of the part's strength, and the UTS of the part varies due to layer orientation. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
