Mechanical Performance of 3D-Printed Cornstarch-Sandstone Sustainable Material

The objective of this research is the improvement of the physical properties of artificial sandstone in order to obtain a printable construction material whose composition and structure is suitable for the design, study and construction of environmentally friendly architectural structures. To investigate the suitability of the researched material for 3D printing and determine the physical and mechanical properties of the starch-based sandstone 3D-printed material, both cylindrical and cellular samples were designed. The 3D-printed artificial starch-sandstone material was found to have satisfactory mechanical properties.
