It is necessary to study a computer control technology to achieve the optimal balance of efficiency and accuracy of automation construction in the large-scale additive manufacturing processes. This paper proposes the mathematical models as a simulation tool and several printing parameters involving the performance capability for full-scale construction by using 3D printing. An approach of interpreting the printing accuracy is presented and the primary monitoring indexes based on computer technology are introduced to achieve high precision construction. A model of path planning and the optimization path generating algorithms under different conditions for the single nozzle system are investigated to minimize the printing duration. The research on the path planning of construction 3D printing for multiple nozzles and
simultaneous multi-equipment based on artificial intelligent algorithm is prospected. The proposed technique provides a link for the integration of computer science technology and construction technology.
