3D PRINTING OF FOAMED CONCRETE

This paper discusses the needs for 3D printing in comparison to conventional construction and proposes foamed concrete material for printing. Example of 3D printing projects under study to overcome housing crisis are presented. Stability and sufficient strength and structural integrity are the main parameters to look for when looking of printable material. The details of these parameters are explained in this paper. Foamed concrete exhibits enhanced mechanical, thermal and acoustic characteristics. Such properties seem to be a suitable alternate choice to fit evolving properties required in the housing industry. Structural response of foamed concrete is still new including mechanical properties, flexural strength, shear strength, short-term and long-term deflections and are still under study by authors.
