Fabrication and Testing of a Vapor Polishing Device for ABS 3D-Printed Parts

Post-processing plays a significant role in improving the surface and mechanical properties of 3D-printed parts. One of these post-processing methods is vapor polishing which utilizes acetone to polish 3D-printed Acrylonitrile Butadiene Styrene (ABS) specimen. This process is usually done using an improvised vapor polishing set-up to achieve the desired surface finish of parts. Hence, in order to accomplish a uniform and standard polishing procedure for laboratory use, a vapor polishing device has been developed in this study. To assess the efficiency of the said device, the resulting surface roughness, dimensional accuracy, and tensile strength of ABS 3D-printed polished specimens have been evaluated and compared to unpolished specimen. The surface roughness of the cube specimen was captured using a Trinocular Microscope and was uploaded to the Mountains9 Topography software. Further, the dimensional accuracy of both polished and unpolished specimen has been measured using a digital Vernier Caliper. The data demonstrated that the polished specimen’s surface was enhanced while its shape, geometry, and dimension were preserved. Tensile tests on two (2) sample sets of polished and unpolished specimens revealed that polishing with acetone vapor using this developed device could improve the specimen’s tensile strength.
