Architectural 3D printing line width compensation method and system

Abstract

The invention relates to a method and system for compensating the line width of 3D building printing. The method includes the following steps: during the 3D printing process, the actual width of the printing line is obtained in real time; The difference of the design width of the line; and judging whether the calculated difference is within the allowable range, if not, adjusting the walking speed and / or output speed of the 3D printer so that the difference is within the allowable range . The architectural 3D printing line width compensation method of the present invention monitors the actual width of the printing line in real time, compares the design width and the actual width, and automatically adjusts the walking speed and / or output of the 3D printer when the difference between the two exceeds the allowable range The speed makes the actual width of the 3D printing line close to the design width, realizing real-time detection, real-time printing, and real-time adjustment, thereby improving the quality and accuracy of the printed components.

Description

technical field [0001] The invention relates to the field of building construction engineering, in particular to a method and system for compensating line width of building 3D printing. Background technique [0002] The material used in architectural 3D printing is cement mortar, which has large particle size and poor fluidity. Therefore, the width of the trajectory line during actual printing is not exactly the same as the design width and the size of the outlet. [0003] The 3D printer includes a rack and a feeder set on the rack. The rack can move in three directions of XYZ, so that the 3D printer can move to any desired position in three-dimensional space. The feeder is provided with a screw rod. And the discharge port, through the rotation of the screw rod, the material is sent out from the discharge port and the printing line is formed at the printing position. [0004] Among them, the walking speed of the frame, the rotation speed of the screw rod, the diameter of th...
