[0002] 3D printers are a type of machine that uses cumulative manufacturing technology, that is, rapid prototyping technology. Since printer materials are usually ejected along the print head by heating, compression and extrusion, the overheated hot end will burn a small amount of printing material, causing material residues to accumulate inside the nozzle. The entire printing material process will be contaminated by foreign matter. The intermittent extrusion of the nozzle will also cause the accumulation of materials to a certain extent. If the front end of the ejection is blocked, etc., it will cause a certain degree of material accumulation in the printing material pipeline, affecting the material supply for subsequent work.
