Modular uninterrupted printing and feeding 3D (three-dimensional) printer system

Abstract

The invention discloses a modular uninterrupted printing and feeding 3D (three-dimensional) printer system. The modular uninterrupted printing and feeding 3D printer system comprises a third connecting pipeline, wherein the upper end of the third connecting pipeline is in through connection with a storage bin being of a circular and hollow structure; a storage bin top cover which is adaptive to the storage bin is arranged at an upper port of the storage bin; and a valve for controlling the conveying of printing raw materials in the storage bin is arranged at the middle part of the third connecting pipeline. The storage bin and a printing spray head of the modular uninterrupted printing and feeding 3D printer system can be disassembled through bayonets, so that different types of storage bins and printing spray heads are selected according to different printing requirements; meanwhile, the continuous driving force can be generated through a gear pump so as to send the printing raw materials to the printing spray head; the volume of the storage bin is much larger than the piston volume of a traditional piston extrusion type 3D printer, and plenty of printing raw materials can be placed in the storage bin, so that when the printing raw material is exhausted, no pause or loading operation is required, and the stability of the environment in which the printing raw materials are located in the printing process is ensured.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a modular 3D printer system for continuous printing and material supply. 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. At present, 3D Printing is usually accomplished with digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others....

AI Technical Summary

Problems solved by technology

[0005] According to the analysis of the above two Chinese patent documents combined with the existing 3D printer technology, the current clinical extrusion 3D printing system often uses the piston extrusion power system to generate pressure to send the printing materials to the printing nozzle. , and then print the ink through the printing nozzle. The core component of the piston extrusion power system is the extrusion piston. Every time before the 3D printing process, the piston needs to be manually opened to perform the loading operation; due to the limited volume of the extrusion piston , the printing process needs to be interrupted many times during the printing process, and the piston is opened to repeatedly load the material. During the printing process, the piston is repeatedly interrupted to disassemble the material, and the printing efficiency is low, and the printing speed is slow; The environment in which the raw materials are located has changed many times, which affects the consistency of the quality of the final printed product, and after the printing is completed, the residual printing materials in the printing nozzle and the printing material delivery connecting pipe are not clear enough. Therefore, those skilled in the art provide a module A 3D printer system for uninterrupted printing and feeding, to solve the problems raised in the above-mentioned background technology
