Abstract

With the growing popularity of additive technologies and the widespread use of 3D printing in various industries – from industry to medicine – the issue of ensuring high surface quality of printed products is becoming increasingly relevant. The aim of the study is to analyze the effect of acetone vapor on the surface quality of 3D printed parts made of acrylonitrile butadiene styrene (ABS). During the experiment, printed samples made of ABS plastic were used. They were placed in a specially designed chamber, where an atmosphere of hot acetone vapors was created. The temperature inside it was maintained at 56°C, which is optimal for dissolving the upper layer of ABS plastic without compromising its structural integrity. The unit is equipped with a temperature sensor and an acetone vapor extraction system, which prevents overexposure and ensures the safety of the process. As a result of the experimental studies of the process of processing printed samples with acetone vapors by the hot method, it was found that the change in roughness parameters over time and the smoothingrate have a nonlinear dependence. It takes 10 minutes to obtain a glossy surface with roughness values of Ra = 0.2 microns and Rz = 1 microns. The smoothing process proved to be effective enough to reduce roughness by 90%. However, it should be noted that such processing also leads to undesirable smoothing of sharp edges, which may be critical for some applications. The obtained experimental dependences of surface roughness indicators on the exposure time in hot acetone vapors and the speed of the smoothing process can be useful for evaluating the effectiveness of chemical post-treatment of the surface with acetone and determining the required degree of treatment. This study demonstrates the importance of precise control of processing time, as excessive exposure can lead to excessive smoothing and loss of critical geometric characteristics. The current results stimulate further research in the field of improving the technology of chemical surface treatment, as well as the development of new control systems and optimization of processing parameters, which will contribute to improving the quality and expanding the use of 3D printed products in various fields.
