Abstract Conventional three-dimensional (3D) printing technology generates objects and parts layer by layer by depositing material along the Z-axis direction. However, when it comes to overhanging structures in the printing process, the conventional printing process needs the creation of additional supporting structures. So, this technique requires additional materials and increases the effective printing time. To overcome these issues, this paper proposes a novel 5-axis dynamic slicing algorithm to achieve non-supporting material printing (NSMP). The original model is sliced by a series of dynamic planes calculated by the skeleton extraction; the 5-axis printing G-code generated from the sliced layers can control the 5-axis printer to complete NSMP. Finally, a comparison between traditional 3D printing and 5-axis printing is presented to test the utility of this strategy.
