Abstract

Fused Deposition Modeling (FDM) is one of the additive manufacturing technology, where printing material is deposited layer by layer onto the surface to form a complex product. FDM technique is widely used in producing prototypes. However, FDM technique has poor surface finishing and staircase effect compared to other additive manufacturing techniques. The purpose of this study was to develop a new post-treatment technique, known as Blow Cold vapor smoothing treatment. Later analysis on the effectiveness of this newly developed post-treatment technique and evaluate the tensile strength of the printed part. The specimens were printed using open source low-cost 3D printer with acrylonitrile-butadiene-styrene (ABS) printing material. Acetone solvent was used in this Blow Cold vapor smoothing treatment. A comparison in term of surface roughness value and tensile strength was made between the treated and untreated specimens. It was found that the surface roughness value on the treated specimen was reduced dramatically. However, this post-treatment technique weaken the material structure of the outer layer on the specimen, which had a slight effect on the tensile strength of the specimen.
