Architectural 3D printing cycle feeding control method and system

Abstract

The present invention relates to a method and system for controlling cyclic feeding of architectural 3D printing materials. The method includes the following steps: during the 3D printing process, real-time monitoring of the material liquid level position in the feeder of the 3D printer to form material level information; judging the obtained material level information; Whether the level information reaches the set minimum position, if so, feed the material into the feeder until the material level information reaches the set maximum position; in the process of feeding, the actual width of the printing line is obtained in real time, and according to the design of the line Calculate the difference between the actual width of the obtained printed line and the design width of the line; and judge whether the calculated difference is within the allowable range, if not, adjust the walking speed and / or output of the 3D printer speed so that the difference is within the allowable range. The control method of the present invention realizes real-time detection, real-time printing, and real-time adjustment, and such feedback can improve the quality of 3D printing, thereby improving the precision of printed components.

Description

technical field [0001] The invention relates to the field of building construction engineering, in particular to a method and system for controlling 3D printing cycle supply of building materials. Background technique [0002] The material used in architectural 3D printing is cement mortar, which has a large particle size and poor fluidity. Therefore, the width of the track line during actual printing is not completely consistent with the design width and the size of the outlet. [0003] The 3D printer includes a frame and a feeder set on the frame. The frame can move along the three directions of XYZ, so that the 3D printer can move to any desired position in the three-dimensional space. The feeder is provided with a screw rod And the material outlet, through the rotation of the screw rod, the material is sent out from the material outlet and forms a printing line at the printing position. [0004] The amount of material in the feeder has a certain impact on the printing q...
