3D printing system for building engineering construction and positioning method of 3D printing system

Abstract

The invention relates to a 3D printing system for building engineering construction and a positioning method of the 3D printing system. The 3D printing system comprises a multi-joint mechanical arm, a 3D printer head printing extrusion head device, an ECU and at least three positioning rods arranged on the periphery of a construction site and not located on the same straight line. A handheld end of the multi-joint mechanical arm is provided with the 3D printer head printing extrusion head device which is provided with a signal transceiver. At least three positioning sources are arranged on each positioning rod. The signal transceiver is in communication with the positioning sources. Signal transceiving ends of the positioning rods are connected with a transceiving end of the ECU, and a drive end of the ECU is connected with a controlled end of the multi-joint mechanical arm. The 3D printing system is high in flexibility and can conduct printing work on buildings of various complex layouts, and meanwhile the system is simple in structure, small in occupied area and convenient to assemble and use.

Description

technical field [0001] The invention relates to a 3D printing system and a positioning method thereof, in particular to a 3D printing system and a positioning method suitable for construction engineering construction, and belongs to the technical field of construction engineering construction. Background technique [0002] 3D printing 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. [0003] 3D printing technology appeared in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After being connected to the computer, the "printing materials" are superimposed layer by layer through computer contro...

Problems solved by technology

[0005] However, the applicant found through research that due to the large area occupied by the construction project, the dimensions and specifications of the three-dimensional control bracket are correspondingly large, the assembly during construction is complicated, and will be affected by terrain conditions. Track movement, easy to be limited by position, difficult to add printing in the architectural layout with more complex structures
