The invention discloses an immersed type ultrasonic surface treatment method for a
polymer 3D printed product and relates to a surface treatment technology based on an
ultrasonic cavitation effect. The surface quality of the printed product is improved. The immersed type ultrasonic surface treatment method for the
polymer 3D printed product is characterized in that the roughness treatment of the surface of the product is carried out on the basis of the
ultrasonic cavitation principle. The method includes the steps that an ultrasonic
grinding device is designed and manufactured and
grinding liquid is prepared. The
grinding liquid (5) is added in a grinding pond (1), and heating is performed. The 3D printed product (3) is clamped through a support (6), and the position is adjusted. The product is immersed in the grinding liquid, an ultrasonic generation module (2) is started, shock
waves generated by blasting of
ultrasonic cavitation bubbles are used for driving
abrasive materials in the grinding liquid to perform physical
impact on the surface of the product, and the surface of the product can be machined. The immersed type ultrasonic surface treatment method for the
polymer 3D printed product has the beneficial effects that the requirements for the size and the shape of the product are low, the material applicability is wide, material fusion is avoided because of low-temperature
processing,
energy consumption is low, and the method is suitable for
machining complicated hook faces and the like.
