Abstract

This paper presents a 3D printing system using intelligence robots for rapid, efficient filling of large construction projects. The 3D printing system includes a construction scheduling system and a 3D assembly line that uses intelligence robots. The 3D scheduling system cuts the 3D digital design model into slices to calculate the filling material information and then plans the transport roads on the site map model for each step in the construction process. The construction robots collect the fill materials when needed and transport the fill materials with intelligent paving and rolling of the fill materials. Once each construction layer is finished, the robots send construction state information to the scheduling system. The complete filling process is then printed step by step under the control of the 3D printing scheduling system.

Key words
