Abstract

Additive manufacturing is a rapidly expanding field of engineering that is accessible to a wide base of people through the process of 3D printing. This process is imperfect as it introduces a series of faults including discontinuities, voids and anisotropic layer adhesion. With the widespread adoption of 3D printing it is imperative to develop methods to mitigate these weaknesses. One such process is Acetone Vapor Smoothing (AVS). This is a surface treatment method that has been shown to be effective in reducing surface roughness of Acrylonitrile Butadiene Styrene (ABS) material. This study is focused on exploring the effect AVS treatment has on the fatigue life of 3D printed ABS components in an effort to increase the effectiveness and scope of these products. To test the AVS process, samples were printed in various layup orientations and were then exposed to an acetone vapor treatment. Drying procedures were varied between different groups, and the fatigue characteristics of the samples were tested on a rotating beam fatigue machine. Our findings indicate that the AVS method can mitigate stress concentrations on the surface and structural uncertainty in the 3D printed ABS components, thereby amplifying fatigue strength under certain conditions. This study also details optimal drying procedures for ABS components, which has been determined to be a combination of air and heat drying. This research has shown that AVS is an effective method to improve the material strengths of ABS material and outlines the optimal conditions for vapor exposure time and drying procedures.
