Method and device for detecting printing quality of 3D printing concrete

Abstract

The invention relates to the technical field of image data processing, and provides a method and device for detecting the printing quality of 3D printing concrete. According to the scheme, concrete material attributes in a fresh mixing state serve as simulation input parameters, computational fluid dynamics software is used for simulating the printing process of the concrete 3D model, theoretical three-dimensional characteristics of the concrete 3D model are calculated based on the simulation result of the 3D printing process, actual printing is carried out to generate a concrete 3D printed piece, and the 3D printed piece is obtained. Carrying out in-situ three-dimensional scanning on the 3D printing piece, and calculating the macroscopic deviation degree, the fine deviation degree, the surface defect rate, the theoretical fluctuation degree, the average expansion rate and the model expansion rate of the 3D printing concrete by utilizing the theoretical three-dimensional characteristics and the actual three-dimensional characteristics of the 3D printing piece of the concrete; according to the indexes, the printing quality of the 3D printing concrete can be comprehensively and quantitatively detected and evaluated from all aspects, it is ensured that the evaluation result is comprehensive and accurate, and the printing quality detection precision of the 3D printing concrete is improved.
