The Effects of Post-Processing Treatment on the Surface Quality and Mechanical Properties of 3D Printed Parts Using Fused Deposition Modeling (FDM) Process

Hassan Isyaku Haruna

Abstract

Fused Deposition Modeling (FDM) is one of the most widely used additive manufacturing techniques due to its cost-effectiveness, ease of use, and versatility in material selection. However, FDM-printed parts often suffer from poor surface quality and anisotropic mechanical properties, which limit their application in functional and high-precision components. Post-processing treatments have emerged as a viable solution to address these limitations. This study investigates the effects of various post-processing techniques on the surface quality and mechanical properties of FDM-printed parts. The study focuses on thermal, chemical, and mechanical post-processing methods, including annealing and vapor smoothing. The results demonstrate significant improvements in surface roughness, tensile strength, and dimensional accuracy, providing valuable insights for optimizing FDM parts for industrial applications. Thermal annealing improved tensile strength and reduced anisotropy but caused slight warping while chemical vapor smoothing significantly reduced surface roughness but slightly decreased mechanical strength due to material softening.
