Abstract

The invention discloses an automatic changing device for the fiber material of a 3D printer and the 3D printer. The automatic changing device comprises an outer frame and a liftable inner frame which is arranged in the outer frame, wherein more than two first positioning mechanisms which are used for detachably fixing printing nozzles are arranged on the outer frame; a nozzle fixing plate which can move along the plane on which the inner frame is located is arranged on the inner frame; a clamping space for elastic locking and positioning is formed between each sunk screw and a corresponding spring base on the nozzle fixing plate; each printing nozzle is provided with a connection plate; each printing nozzle is matched with the nozzle fixing plate through the bottom plate of the corresponding connection plate to form a spliced printing head, and is matched with the corresponding first positioning mechanism on the outer frame through the side plate of the corresponding connection plate to form a standby printing head, so that free switch between work and standby of the printing heads is realized; the bottom plates are vertical to the side plates, so that the positioning direction of standby warehousing of the printing nozzles and the positioning direction of loading of the printing nozzles are separate from each other, and do not interfere with each other; reliability of automatic fiber material changing is improved; and the splicing structures are applicable to printing nozzles of different sizes.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an automatic replacement device for filaments of a 3D printer. In addition, the present invention also relates to a 3D printer comprising the above-mentioned 3D printer filament automatic replacement device. Background technique [0002] 3D printing technology is a method based on three-dimensional model data, which uses materials to be superimposed layer by layer to manufacture solid parts. This technology has been widely used in the fields of machinery, automobile, education, medical treatment, construction industry and national defense, and has achieved significant economic benefits. Among them, Fused Deposition Manufacturing (FDM) has become the most widely used 3D printing technology due to its many advantages such as simple operation and fast forming speed. Although 3D printers based on FDM technology are the most widely used in 3D printing, and the printing technolog...
