Lattice-structured concrete three-dimensional (3d) printing methods for component forming

Abstract

Provide is a lattice-structured concrete 3D printing method for large-scale component forming. The method includes: S, 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; S, obtaining a print head configuration and setting a printing parameter; S, 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; S, controlling one or more print heads to perform 3D printing based on the lattice information; and S, post-processing a printed component to obtain a finished product. The method can be applied to 3D printing and forming of concrete structures.
