In recent, 3D printers have been attracting attention worldwide, and the main materials used are ABS, PLA, and acrylic resins. In addition, there have already been many reports, mainly from overseas, on the construction of full-scale pedestrian bridges and simple houses using cement-based materials. Although extrusion deposition method is the mainstream of current 3D printers for construction, there are some problems. Therefore, we thought that we could solve this problem by using the powder deposition method. We created an experimental machine that ejects powder at any location, and we sculpted by manually sprinkling water at any location where we wanted to solidify. The purpose of this study is to verify whether modeling is possible using binder jetting. Experiments were conducted to form basic objects of rectangular and arc systems using binder jetting, and we report that we succeeded in forming the target shapes.
