Multi-spray-head three-dimensional printer

Abstract

The invention provides a multi-spray-head three-dimensional printer. The multi-spray-head three-dimensional printer comprises a material dividing plate, a baffle, a first drive mechanism and a spray nozzle assembly; the material dividing plate is of an annular shape, the material dividing plate is internally provided with a plurality of material dividing cavities, and the bottom end of each material dividing cavity is provided with a material discharging hole; the baffle is located under the material dividing plate and is rotatably connected with the material discharging plate, and the baffle is provided with a first material guiding hole which can communicate with the multiple material discharging holes and penetrates through the upper surfaces and the lower surfaces of the material discharging holes; the spray nozzle assembly comprises a connection plate, a second drive mechanism and a plurality of spray nozzles of different diameters, the connection plate is located under the baffle and is rotatably connected with the baffle, the connection plate is provided with a plurality of second material guiding holes which can communicate with the first material guiding hole and penetrate through the upper surface and the lower surface of the first material guiding hole, and the multiple spray nozzles are all installed on the connection plate. Through the arrangement of the multiple spray nozzles of different diameters, different use demands can be met; and the baffle can prevent printed materials in other material dividing cavities which are not used from being leaked out and falling on the surface of a printed object, the wiredrawing phenomenon is avoided, and the delicate degree of a printed product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a multi-nozzle three-dimensional printer. Background technique [0002] A three-dimensional printer is a rapid prototyping technology machine, which is based on a digital model file, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. It is a cumulative manufacturing technology. Technology, to manufacture three-dimensional objects by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the three-dimensional printer, the machine will build the product layer by layer according to the program, and the printed product, and ready to use. 3D printers used to be used to make models in the fields of mold making, industrial design, etc., and are now gradually being used for direct manufacturing of some products, which can be used in jewelry, footwear, industri...

Problems solved by technology

The core component of a 3D printer is the print nozzle. At present, the main 3D printer nozzles are single nozzles, and the radius of the nozzle cannot be changed, which is very inconvenient to use.
