Abstract
This paper proposes a continuous path generation scheme for large-scale additive manufacturing technology. In this study, a continuous path approach is proposed, and it allows the creation of paths with continuous sparse adhesion characteristics in a narrow model. A single-layer continuous path is divided into a walled path and a fill path. Wall paths are formed by spiral paths, and sparse fill paths are obtained by combining contour paths and zigzag paths. In addition, the proposed guide-line method achieves continuous path planning for models with corners. This path-planning method offers various advantages over traditional methods. Sparse-filling paths allow structure fabrication with specific strength advantages, and periodic paths allow uniform temperatures during processing. In addition, the continuous path makes the structure manufacturing with better molding accuracy and eliminates the stringing problem. This path planning method is a proposed solution for large mold additive manufacturing, and it can be applied to the industrial mold manufacturing industry.
