Extrusion device and 3D printer

Abstract

The invention discloses an extrusion device and a 3D printer. The extrusion device comprises a plurality of extrusion mechanisms and adjusting mechanisms which are distributed in an array mode. The extrusion mechanism comprises a driving assembly and feeding assemblies, the feeding assemblies are connected with an output end of the driving assembly, the feeding assemblies are used for extruding consumables, and the driving assembly comprises an ultrathin motor. The adjusting mechanism is connected with the plurality of feeding assemblies and used for adjusting the pressing force of the feeding assemblies on the consumables. The extrusion mechanisms of the extrusion device are small in size, so that the size of the plurality of extrusion mechanisms distributed in the array mode is further reduced, the extrusion device can convey the consumables to a spray head device with a plurality of spray heads, a stable foundation is provided for multi-spray-head 3D printing, high-speed and high-precision multi-spray-head 3D printing is conveniently realized, and then the production efficiency is increased, and the printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an extrusion device and a 3D printer. Background technique [0002] The extrusion mechanism of a 3D printer usually has a large volume, and when multiple extrusion mechanisms are combined together, they occupy a larger area, making it difficult to perform actual 3D printing. However, with the development of 3D printing technology, multi-nozzle 3D printing has become an important breakthrough point in the industry. Multi-nozzle 3D printing inevitably requires multiple extrusion mechanisms to be installed at the same time, and the combined volume of the extrusion mechanisms in the existing technology is difficult to meet the demand. , has hindered the development of multi-nozzle 3D printing technology. [0003] Therefore, there is an urgent need for an extrusion device and a 3D printer, which can provide a solid foundation for multi-nozzle 3D printing, facilitate the realizati...
