The Post-Processing of Additive Manufactured Polymeric and Metallic Parts

The traditional manufacturing industry has been revolutionized with the introduction of additive which is based on layer-by-layer manufacturing. Due to these tool-free techniques, complex shape becomes much more convenient in comparison machining. However, comes its inherent process characteristics high surface roughness, turn effect fatigue strength as well residual stresses. Therefore, this paper, common post-processing techniques for manufactured (AM) parts were examined. main objective was analyze finishing processes terms their ability finish complicated surfaces and performance expressed average roughness (Sa Ra). divided according materials they applied material removal mechanism. It found that chemical significantly reduces can be used geometry. Laser finishing, other hand, cannot intricate internal surfaces. Among mechanical abrasion methods, abrasive flow shows optimum results freeform cavities improved accuracy both polymer metal parts. it that, general, most lack Moreover, although methods are conducted using single processes, AM finished hybrid successive reap benefits different overcome limitation individual process.
