Cement-based composition and additive manufacturing method for 3D printing architectural exterior finishing materials

摘要

The present invention relates to a cement-based composition for 3D printing and a manufacturing method for manufacturing a laminated building exterior panel and a sculpture, which can stably maintain a shape during lamination of atypical 3D printed architectural exterior panels and sculptures. The present invention is 20 to 60% by weight of cement, 5 to 20% by weight of fly ash, 30 to 70% by weight of silica sand No. 8 and 1 to 10% by weight of EVA powder resin, 0.5 to 3% by weight of methylcellulose, It is characterized in that it contains 0.5 to 3% by weight of calcium formate powder, 0.1 to 2% by weight of carboxyl fluidizing agent powder.
