Abstract
Additive Manufacturing (AM) is the process of joining materials to create objects from the CAD model via layer upon layer. One of the common technologies of Additive Manufacturing is Fused Deposition Modeling (FDM), which uses extrusion to form parts. FDM technology has been applied in many applications such as consumer product manufacturing as well as end-used parts. However, FDM suffers badly from low surface quality due to the staircase effect and post treatment is required. In order to yield significant improvement of the surface roughness, L.M Galantucci (2009) stated that chemical treatment is one of the economic and fast method to enhance surface finish ABS (Acrylonitrile- Butadiene-Styrene) fused modeled part by performing chemical treatment in a acetone solution. Therefore, this research aims to investigate the influence of chemical treatment on the FDM used part in terms of surface roughness as well as strength. In this project, ten specimens of standard ASTM D638 dogbone specimen and clips will be fabricated using MOJO 3D Printer. As a result, the chemically treated dogbone has dramatically improved in term of surface roughness compared to the untreated dogbone with 97.2% improvement. The treated clips show significantly improved in term of surface finish compared to the untreated clips by 96.12% improvement. However, the tensile strength of the dogbone is reduced 42.58% due to the joining effects of filaments. Finite Element Analysis (FEA) is used to validate the data obtained. In a nutshell, chemical treatment is an economic and sustainable approach to enhance the surface quality of Additive Manufacturing parts.
