Extended Lattice Model to Simulate the Printing Process of 3D Printed Cementitious Materials

Research output: Chapter in Book/Conference proceedings/Edited volumeChapterScientificpeer-review

Abstract

This paper reports an extended lattice model for printing process simulation of 3D printed cementitious materials. In this model, several influencing factors such as material and geometric nonlinearity are considered. Using this model, green strength of cementitious material is investigated, deformation and crack pattern can be derived, which is close to the experimental result. Subsequently, numerical analysis of 3D printing is conducted for the simulation about printing process. Imperfections arising in the printing process can be incorporated and two failure modes including the elastic buckling and plastic collapse can be simulated through this model.
