Abstract

Additive manufacturing (AM), commonly referred to as 3D printing, has emerged as a transformative technology within the manufacturing sector, offering distinct advantages such as intricate design capabilities and rapid prototyping. However, the inherent surface roughness and imperfections associated with AM processes necessitate the implementation of effective post-processing techniques to meet industry standards. This paper presents an investigation of the effects of mass finishing processes on metal workpieces fabricated using the Atomic Diffusion Additive Manufacturing (ADAM) process. Various assessments, including tensile strength testing, surface roughness measurement, hardness measurement, and surface topography analysis, were conducted to evaluate the impact of the mass finishing process on the surface finish and mechanical properties of the 3D printed components. The results demonstrate improvements in surface roughness parameters, hardness, and ultimate tensile strength (UTS) following the mass finishing process, with noteworthy observations regarding the effects of prolonged post-processing duration. This research provides valuable insights into optimizing post-processing techniques to enhance the surface quality and mechanical performance of ADAM-produced metal components, thus contributing to the advancement of additive manufacturing.
