This paper presents an adaptive tool path generation method for Fused Deposition Modeling (FDM), which provides an effective approach for dieless forming and reverse engineering. The proposed method consists of three steps. First, an adaptive slicing considering both surface quality and building time is proposed for following tool path generation. Second, a hybrid tool path strategy is introduced to improve the boundary contour's accuracy and reduce the time for interior filling. This step is an adaptive process to choose an appropriate proportional relationship between the two types of tool paths: contour parallel path and direction parallel path according to the specific fabrication requirements. For further improvement on fabrication quality, a tool path adjustment is employed on the original tool paths. A case study of a sliced layer is used to verify the feasibility of the proposed method and demonstrate it can accomplish the fabrication of models with high surface quality and short building time.
