Cleaning device and method for multi-material 3D printing

Abstract

The invention provides a cleaning device and method for multi-material 3D printing. The device comprises a base, a printing platform unit and a cleaning and air drying unit. The cleaning and air-drying unit comprises a cleaning box unit, a cleaning box rotation switching mechanism, an air outlet plate and an air outlet plate rotation driving mechanism; the cleaning box rotation switching mechanism is connected with the cleaning box unit and used for rotating the cleaning box unit to the position under the printing platform. The air outlet plate rotation driving mechanism is connected with the air outlet plate and used for driving the air outlet plate to rotate horizontally. The cleaning and air-drying device is controlled in a rotary switching mode, and in the whole 3D printing and cleaning and air-drying process, the position of the printing platform is fixed, so that the printing precision of the printing platform is improved. Besides, the cleaning and air-drying device integrates two functions of cleaning and air-drying, the functions are diversified, printed pieces are air-dried after being cleaned, it is guaranteed that printing materials cannot be polluted mutually in the printing task execution process, and therefore the quality of printed products is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a cleaning device and method for multi-material 3D printing. Background technique [0002] At present, the 3D printing method is mainly as follows: after the 3D printing of the parts is completed, the parts are immersed in the cleaning box to clean the parts and remove the printing residue on the surface of the parts. The cleaning box designed for this method is a conventional cleaning box. In a single job, the cleaning frequency is low, and the cleaning target is mainly resin without particle deposition. [0003] The above cleaning box has a single function, and, compared with the 3D printing equipment, it is an independent cleaning box, which cannot be applied to switch printing and cleaning between different materials during the 3D printing process of multiple materials. Contents of the invention [0004] Aiming at the defects existing in the prior art, the ...
