Abstract

The invention relates to a quantitative mixing and conveying device for 3D printing. The quantitative mixing and conveying device comprises a mixing feeder, a mixing and conveying guide pipe and a needle type extrusion nozzle; the mixing feeder comprises a mixing feeding shell, a sealing gasket, a mixing feeding screw, a mixing feeding motor, a feeding port, a quantitative feeder shell, a quantitative feeding screw, a quantitative feeding motor and a mixer base plate; the mixing and conveying guide pipe comprises a guide pipe connector, a conveying guide pipe and a conveying spring; and the needle type extrusion nozzle comprises a connecting mechanism, an extrusion screw, a printing needle, an extrusion head, a sealing gasket and a counter flange. According to the quantitative mixing and conveying device, the problems of unstable feeding extrusion, slurry solid-liquid separation and slurry conveying process blockage in the manufacturing process are solved, long-time continuous and stable 3D printing, and quantitative input of variable-component and multi-component slurry can be achieved, printing of variable-component and multi-component material and gradient material can be achieved, and the overall structure is simplified.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a quantitative mixing and conveying device for 3D printing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology (AM), belongs to a rapid prototyping technology (RP). Three-dimensional objects are constructed by printing and superimposing successive layers of different shapes layer by layer. Compared with the traditional casting process, the biggest advantage of 3D printing is the ability to freely manufacture complex parts directly from raw materials, without involving traditional manufacturing methods such as extrusion, forging, casting and secondary processing to obtain the desired shape , and the utilization rate of raw materials is nearly 100%. [0003] The representative printing method based on material extrusion is fused deposition modeling (FDM). FDM is the abbreviation of "Fused Deposition Modeling", that is, fusion depositio...
