Abstract

The invention relates to a multi-material three-dimensional printer nozzle. The multi-material three-dimensional printer nozzle comprises a nozzle seat and a nozzle body. A clamping and conveying bin is arranged on one side of the top of the nozzle seat. A clamping and conveying motor is arranged on the clamping and conveying bin. A main clamping and conveying wheel is arranged on the clamping and conveying bin. A diversion hole is formed in the nozzle seat. Heating pipes are arranged on the nozzle seat. A guide block is arranged on the other side of the top face of the nozzle seat. Guide grooves are formed in the guide block. An opening is formed in the side, facing the clamping and conveying bin, of each guide groove. The cross section of each guide groove is in a sector shape. An auxiliary clamping and conveying wheel is arranged in each guide groove. A guide column is arranged at the bottom of the guide block. A guide sleeve is arranged on the nozzle seat. A screw and a material switching stepping motor are arranged on the side face of the guide block. A nut matched with the screw is arranged on the nozzle seat. An annular boss is arranged at the bottom of the guide block. Strip-shaped bosses are arranged on the two sides of the diversion hole in the top face of the nozzle seat. The strip-shaped bosses and the annular boss form a shearing blade. According to the multi-material three-dimensional printer nozzle, different raw materials are switched through the horizontally-moving guide block and enter the diversion hole, the structure is simple, continuous printing can be achieved, the efficiency is high, the shearing faces are level, and it is not necessary to additionally arrange heat dissipation equipment on the guide block.

Description

technical field [0001] The invention relates to three-dimensional printer equipment, in particular to a multi-material three-dimensional printer nozzle. Background technique [0002] 3D printing is a rapid prototyping technology based on digital model files, using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. Especially some high-value applications, such as hip joints or teeth, or some aircraft parts, etc., already have parts printed using this technology. The technique is also known as cumulative manufacturing, as the item is printed by building up the material layer by layer. Most of the existing 3D printers can only print one kind of consumables at a time, but it is of great practical significance to be able to print multiple consumables...
