Uniaxial move multi-track parallel independent type 3D printing device and printing method

Abstract

The invention discloses a uniaxial move multi-track parallel independent type 3D printing device and printing method, and relates to the technical field of building construction, and the printing device and printing method aim to solve the problems that an existing 3D printing device is low in printing efficiency, not high in precision and poor in flexibility. The uniaxial move multi-track parallel independent type 3D printing device comprises a climbing device capable of moving vertically relative to a printed building body and a printing device body connected with climbing components. The printing device body comprises a track frame and printing head cross beams. The track frame comprises a plurality of grid units. Each grid unit is internally provided with the multiple printing head cross beams arranged independently, and the two ends of each printing head cross beam can slide along the track frame. Printing heads which can synchronously move on a horizontal printing surface with the printing head cross beams are densely arranged on the printing head cross beams. The printing heads are used for ejecting building materials. Printing construction conducted on a current cross section layer can be completed just through one-time movement of the printing head cross beams. The printing device body is jacked up to the height of a to-be-printed cross section layer of the upper story of the building body by controlling the climbing device, and accordingly all cross section layers are printed from bottom to top in a layer-by-layer mode till printing construction of the whole building body is completed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a single-axis mobile 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 buildings have 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 venues. low. Therefore, how to provide a single-axis mobile multi-track parallel independent 3D printing device and printing method suitable for the construction of large-scale buildings with high printing efficiency, high precision and high flexibility is a technical problem that those skilled in the art need to solve urgently. . SUMMARY OF THE INVENTION ...

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
