Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional printers, in particular to an automatic material spraying device for a three-dimensional printer. Background Art

[0002] 3D printing is a type of rapid prototyping technology. It is a technology that uses a digital model file as the basis, using materials such as plastics, which are squeezed out through a nozzle with a fine nozzle and begin to solidify when the temperature is lower than the curing temperature. The finished product is finally formed by the accumulation of layers of plastic materials, and the object is constructed by printing layer by layer.

[0003] The current spraying device of a 3D printer can usually only realize the spraying function. When the material condenses and becomes clogged inside, it needs to be manually disassembled and cleaned. The cleaning operation is cumbersome and affects the efficiency of use. Therefore, we propose an automatic spraying device for a 3D printer to solve this problem. Utility Model Content
