Abstract

The invention relates to the technical field of 3D printing, in particular to a 3D printing spray head system. The 3D printing spray head system comprises a fusing spray head shell and a feeding throat pipe, and a vertical material mixing cavity is formed in the fusing spray head shell; the bottom end of the material fixing cavity communicates with a spiral discharging channel which communicates with a spray nozzle; the spray nozzle penetrates the fusing spray head shell and is connected with the fusing spray head shell in a threaded manner; the top end of the material mixing cavity communicates with a plurality of feeding channels which communicate with a connection channel; the upper surface of the fusing spray head shell is provided with an installing hole which is in threaded connection with the feeding throat pipe; the feeding throat pipe communicates with the connection channel, and is sleeved with a heating pipe; and the feeding throat pipe is provided with a heat insulating gasket which is located between the heating pipe and the fusing spray head shell. The spray head system is designed into the multi-feeding and single-discharging spray head mode, the feeding speed in theprinting process can be increased due to the multi-feeding mode, discharging manners of a plurality of materials can be in a mixed state due to the single-discharging mode, and the strength and the precision of printed finished products are guaranteed.

Description

technical field [0001] The invention belongs to the field of 3D printing equipment, and in particular relates to a 3D printing nozzle system. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. The existing 3D printing equipment includes a computer control system, a feeding system and a printing system. The printing system includes a motion system and a nozzle system. The motion system controls the movement path of the nozzle system to complete the printing of the model. [0003] At present, the design of 3D printing nozzle system is mostly based on single feed-single discharge nozzle or double feed-double discharge nozzle. Generally speaking, the product can only be printed by simply covering and superimposing the material, so that the structure of the product will be layered w...
