In this poster, we propose a multi-DOF (degree of freedom) 3D printing system with visual surveillance assistance. Different from common 3D printers with only three translational axes, our printer is equipped with two additional rotational axes, and a visual surveillance

module which helps to enhance the printing precision during the rotation. The input model is first segmented such that each part can be printed in a direction with less supporting material.

We demonstrate that the proposed system could save most of the supporting materials compared to existing works.
