Additive Manufacturing, Surface Integrity, Complex Metallic Parts, Finishing ProcessAbstract
Nowadays, metallic 3D printed parts are widely used in almost every sector, such as aerospace, automobile, medical, etc. However, the printed parts cannot be directly utilized as the surface roughness is very high. Therefore, post-processing techniques are required to improve its surface integrity. In the present manuscript, techniques such as Abrasive flow finishing (AFF), Magnetorheological abrasive flow finishing (MRAFF), Aerolap polishing (AP), and Laser polishing (LP) have been discussed. The mechanism of each process, along with its pros and cons, and applications also be discussed. This will help the researchers and industries to analyse which process is more efficient for a specific application.
