In this presentation, we will discuss different strategies that we are using to target the challenge of producing reliable surface finished (post-processing) components that meet the requirements of the biomedical and aerospace industries. We will present the use and applicability of Chemically Accelerated Vibratory Finishing (CAVF), a surface treatment process (known as ISF(R)-isotropic superfinishing) capable of: Accommodating a wide gamut of shapes, including very complex geometries,polishing the surface of the part in their exterior and interior,removing loose powder particles associated with the AM process, and considered in the aerospace industry as foreign object debris (FOD), removing structural supports produced during the printing process, and improving the mechanical strength of the components. The process was designed to eliminate surface defects and stress raisers from the surface to strengthen the performance of the components under mechanical stress. In addition, we will present several examples as case studies of actual aerospace and biomedical parts with extreme surface roughness and surface defects, both eliminated using these techniques.
