Summary

This chapter presents an overview of the tools, approaches and recent results of numerical modeling in the field of 3D concrete printing. After summarizing digital tools for geometric modeling and virtual printing, the chapter deals the state of the art in digital modeling of the 3D printing process. In the context of the construction sector's move toward digitalization, the integration of BIM (building information modeling) with 3D printing activities has become a challenge for many research efforts. The developments and applications of numerical tools in the 3D printing process for concrete structures have demonstrated the effectiveness of numerical modeling in this field. The stochastic optimization procedure could be widely useful for establishing design regulations for structures built using 3D printing. On a large scale, the interest of numerical modeling lies in predicting failure modes such as elastic buckling and plastic collapse of the structure, phenomena commonly observed during printing.
