Single-axis mobile multi-track parallel independent 3D printing device and printing method

Abstract

A single-axis moving multi-track parallel independent 3D printing device and printing method of the present invention relate to the technical field of building construction and aim at the problems of low printing efficiency, low precision and poor flexibility of existing 3D printing devices. It includes a climbing device that can move vertically relative to the printed building and a printing device connected to the climbing member; the printing device includes a track frame and a print head beam, and the track frame contains multiple grid units, and each grid unit is set with multiple grid units. A print head beam that is independently set and can slide along the track frame at both ends. The print head beam is densely covered with print heads that can move synchronously with it on the horizontal printing surface. The print head ejects building materials, and the print head beam moves once to complete the current beam. Printing construction of cross-section layers; by controlling the climbing device, the printing device is raised to the height of the upper layer of the building to be printed, so that each cross-section layer is printed layer by layer from bottom to top until the printing construction of the whole building is completed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a single-axis moving multi-track parallel independent 3D printing device and a printing method. Background technique [0002] At present, 3D printing technology is developing rapidly. Among them, 3D printing architecture has the advantages of high degree of automation, one-time molding, and less construction consumables and process losses. However, the existing 3D printing device uses a single print head, which is only suitable for the construction of small-scale buildings such as residential buildings and small stadiums. low. Therefore, how to provide a single-axis mobile multi-track parallel independent 3D printing device and printing method suitable for large-scale building construction with printing efficiency, high precision and high flexibility is a technical problem urgently needed by those skilled in the art. . Contents of the invention [0003] Aiming ...

Problems solved by technology

[0003] Aiming at the problems that the single print head of the existing 3D printing device has low working efficiency, low printing accuracy, and cannot meet the construction needs of large-scale buildings, the purpose of the present invention is to provide a single-axis moving multi-track parallel independent 3D printing Device and printing method, the single-axis mobile multi-track parallel independent 3D printing device divides the track frame composed of track beams and connecting beams into several grid units with equal areas, and at least two printing heads are arranged in each grid unit Beams, all print head beams located in the same grid unit are arranged in parallel and at intervals, both ends of each print head beam can slide along the track beam, each print head beam is densely covered with print heads, and the print head and print head beam Synchronous one-way movement on the horizontal printing surface, on the one hand, the two-way movement of the 3D printing device in the horizontal plane is changed to a single-axis one-way movement, which can improve the reliability of the 3D printing device; on the other hand, each print head beam is densely distributed The printing head, so that the printing head beam can complete the printing of a building cross-section layer every time it moves, and the movement of the printing head beam in different blocks is independent, which significantly improves the printing efficiency
