A hybrid tool-path with no pause generation algorithm for 3D printing

Abstract

With the development of the manufacturing industry, 3D printing has gradually become a focus of attention due to its unique advantages such as fast speed and low threshold. As an important part of the printing process, scanning path planning directly affects the quality of the molded part. Based on the existing path research, this paper proposes a new filling algorithm, which uses the idea of Fermat spiral to achieve continuous filling, and the contour offset, partition and some unfilled areas are optimized respectively. Finally, the new algorithm is tested on common graphics to prove its superiority.
