Abstract: The traditional filling method of thin shell 3D printing material has poor capturing effect on missing features, low filling efficiency and poor economic benefit. Therefore, this paper proposes a thin shell 3D printing material filling method based on implicit surface. The 3D material filling process of implicit surface is designed, and the implicit surface is constructed to mark the image surface features of material defects; the two-phase segmentation is used to realise the mesh division of material defect image, and the thin shell 3D printing material filling algorithm is designed, and finally the material filling is realised by 3D printing technology. The experimental results show that the average accuracy of missing feature capture is 97.35%, the average length of filling path is 570.3 mm, and the average filling time is 3.65 min.

Keywords: 3D printing; implicit surface; two-phase segmentation; filling efficiency.
