Abstract

With the rapid development of industrial automation and 3D printing technology for decades, its related technologies have brought a certain degree of change to the traditional construction methods. Among them, the method of using 3D printing technology to realize the construction of complex geometric structures has considerable potential in automated construction. Traditional FDM 3D printer is restricted by its degree of freedom, frame, and printing methods, resulting in many restrictions on the scale, shape, and structure of its printed products, which affects the application of this technology in the fabrication of high stiffness-to-weight ratio building components. This paper proposes a spatial 3D printing system based on industrial robots, aim to realize the fabrication of high stiffness-to-weight ratio building components. This system improves the hardware and control system of the existing FDM 3D printer. Through the mechanical process to adjust the different parameters of the system, the properties of
the material can be affected during the printing process to obtain controllable surface texture and node enhancement. This system combined with mechanical process can increase the flexibility of 3D printed components’ structure and improve the stiffness-to-weight ratio of printed building components, then optimize the feasibility of 3D printed products in building components.
