Surface finishing methods play a vital role in improving the surface characteristics of orthopedic implants. This chapter provides a comprehensive review of mechanical finishing techniques used to improve the surface quality of AM components. It discusses techniques such as manual sanding, ball burnishing, abrasive flow machining, vibratory finishing, and many more. This chapter discusses the principles, advantages, and limitations of each technique and considers factors like material removal rates, surface finish achievable, and process suitability for various AM materials and geometries. It also deals with the effect of these finishing processes on the mechanical properties of AM parts such as strength, fatigue resistance, and wear behavior. Finally, the chapter points out significant applications of such finishing techniques in various industries to show their importance in realizing the full potential of AM for high-quality, functional components.
