3D printer spray head cleaning system and cleaning method thereof

Abstract

The invention discloses a 3D printer spray head cleaning system, and is installed on a 3D printer. The 3D printer spray head cleaning system comprises a cleaning component used for cleaning a spray head, wherein the cleaning component comprises scraping plates used for cleaning the spray head, and a waste material pool used for containing waste materials cleaned from the spray head; and the scraping plates are installed in the water material pool. A cleaning method comprises the following steps that: under the driving of a printing platform or through an automatic movement mechanism, the cleaning component moves to be below the printing platform; the printing spray head extrudes waste wax in a wax cavity through air; the scraping plates scrape the waste materials on the bottom of the printing spray head; the cleaning component moves to be below the printing platform; and new wax enters the wax cavity to be subjected to printing injection, and the new wax is injected to the waste material pool. A whole cleaning process is controlled through a control system, a manual operation is not required, and cleaning efficiency is high.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a 3D printer nozzle cleaning system and a cleaning method thereof. Background technique [0002] 3D printers build three-dimensional models through additive manufacturing methods. Wax type 3D printer is a kind of additive manufacturing equipment. It uses blue wax as printing material and white wax as supporting material. It sprays high-temperature heated wax onto the printing platform, and builds models by layer-by-layer stacking. Due to the advantages of high precision and smooth surface of wax-sprayed 3D printing models, wax-sprayed 3D printers are widely used in jewelry, aerospace, engine and other manufacturing industries. The printing materials used in the wax spray 3D printer are white wax and blue wax. The wax is packed in a container, and the container is put into the ink supply assembly. The blue wax in the container flows into the ink supply assembly, and flows i...

Problems solved by technology

These waste waxes may block the nozzles and cause the print nozzles to fail to eject, so the print nozzles need to be cleaned regularly

The existing nozzle cleaning method uses manual cleaning. When cleaning, the printing nozzle needs to be heated to melt the wax, but this cleaning method is easy to cause burns to the cleaning personnel, resulting in inconvenient cleaning of the nozzle
