Abstract
Provide is a lattice-structured concrete 3D printing method for large-scale component forming. The method includes: S1, obtaining 3D data of a component to be printed and establishing a 3D model of the component to be printed, wherein the 3D data includes a coordinate set of all points and lines of the component to be printed in a 3D space; S2, obtaining a print head configuration and setting a printing parameter; S3, obtaining the printing parameter and generating lattice information of the 3D model using an improved slicing algorithm based on a feature of the component to be printed; S4, controlling one or more print heads to perform 3D printing based on the lattice information; and S5, post-processing a printed component to obtain a finished product. The method can be applied to 3D printing and forming of concrete structures.
