Fused deposition modeling (FDM) is a fabrication method used in additive manufacturing. In FDM, support materials that act as splints can be required depending on the shape of the object, and the support material must be removed after the object is completed. The support material can be removed cleanly by using a water-soluble support material, but this method is lengthy. Ultrasonic washing with running water can remove the support materials locally and quickly by using the cavitation or acoustic flow generated by irradiating the water with strong ultrasonic waves. In this study, ultrasonic washing with running water was investigated using polyvinyl alcohol as a model of soiling. Running water irradiated with ultrasonic waves gave a substantially higher washing rate than unirradiated running water.
