コンクリートを材料とした3Dプリンタ

抄録

There are problems such as a shortage of workers and construction equipment, waste, and the inability to secure accommodation facilities required by workers when building temporary housing. Therefore, if it is possible to build a building using a 3D printer, we thought that it would not only solve these problems but could also be used at construction sites. In recent years, 3D printer has attracted worldwide attention, and 3D printer for home use have become so popular that they are sold. ABS, PLA , and acrylic resin are used as the main materials for 3D printer. Also, many cases have already been reported, mainly abroad countries, in which construction materials such as cement-based materials are used to construct members that make up full-scale pedestrian bridges and simple dwellings. The purpose of this research is to develop a super-large binder jetting concrete 3D printer.
