Removal of extraneous matter by ultrasonic washing in running water

Among the fabrication methods of additive manufacturing technology is the fabrication method called fused deposition mod (FDM). In FDM, support materials that act as splints are required depending on the shape of the shaped object, and the support material must be removed after the model has been completed. Removal of support material can be done cleanly by using a water-soluble support material, but it takes a long time. In order to remove those support materials, a washing method using running water type ultrasonic washing as a washing method that can be performed locally in a short time by using cavitation or acoustic flow generated when strong sonic waves are irradiated in running water. In this study, washing effect of running water type ultrasonic washing was investigated using polyvinyl alcohol as a model of soiling. As a result of the experiment, when ultrasonic waves were irradiated in the running water, a high washing effect was obtained as compared with the case which ultrasonic waves were not irradiated in running water.
