A kind of 3d printing equipment, 3d printing system and 3d printing method

Abstract

The invention discloses 3D printing equipment, a 3D printing system and a 3D printing method. The 3D printing equipment comprises a travelling mechanism, a printing mechanism, a feeding mechanism anda control mechanism, wherein the printing mechanism is carried on the travelling mechanism, and the travelling mechanism comprises a positioning device; and the printing mechanism comprises a printingspray head, a spray head driving and transmission device and a spray head positioning device, and the spray head positioning device is used for positioning the printing spray head and compensating the positioning deviation of the printing spray head. According to the 3D printing equipment, the 3D printing system and the 3D printing method, two-stage positioning is adopted, the first-stage positioning is controlled within a proper error range through the travelling mechanism, and the second-stage positioning is completed through a spray head moving module and a positioning deviation compensation module of the printing mechanism, so that accurate positioning is achieved; and according to the 3D printing equipment, the 3D printing system and the 3D printing method, multiple technical advantages are integrated, printing of a small printer on a large-size structure is achieved, multi-thread simultaneous printing of multiple materials is achieved, and indoor space printing is achieved, so that application and popularization of the 3D printing technology are promoted, and the comprehensive cost of building construction is reduced.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device, a 3D printing system and a 3D printing method. Background technique [0002] In the 1980s, 3D printing began to be studied. Since then, 3D printing technology has been applied in high-end manufacturing, education, architectural design, medical care, aerospace, cultural creativity and other fields relying on cutting-edge technologies in multiple disciplines, showing impressive results. Exciting prospects for development. In the book "The Third Industrial Revolution", the British "Economist" magazine regards 3D printing technology as one of the important symbols of the third industrial revolution, which has aroused people's attention to 3D printing. The US "Time" magazine listed 3D printing as "the ten fastest growing industries in the United States". According to data from Wohlers Associates Shanghai Institute of Science and Technology Infor...

Problems solved by technology

[0005] 1. The displacement of the nozzle is limited within the frame of the gantry, which leads to the 3D printer of the gantry system cannot be larger than the object of the gantry, and the large-sized gantry is expensive and has low precision, even for some buildings. structure, it is almost impossible to manufacture a super-large gantry system that meets the requirements;

[0006] 2. A set of gantry system can usually only be equipped with one print head, and correspondingly, it can only print one material. It cannot perform parallel printing of multiple materials and multiple processes, and cannot meet the long construction period, many processes, and complicated types of work in the construction industry. construction status;

[0007] 3. In view of the working method of the gantry system, it is impossible to further process the printed components, and there are still many processes after the main structure is completed in the construction industry, which reduces the applicability of 3D printing technology to the construction industry

[0008] For architectural 3D printing, at present, the nozzle is mounted on an industrial robot, and then the robot is mounted on a walking mechanism such as a crawler vehicle to overcome the shortcomings of the gantry-type architectural 3D printer that cannot print large-scale structures, but the industrial robot The cost is very expensive and the control system is complex
