“…Users can easily take materials from the local area and make their own ceramic models to meet the needs of individuals. As a green and reusable printing material, unlike the thermoplastic materials used in general 3D printing processes, such as fused deposition modeling (FDM), ceramic clay materials will remain relatively soft throughout the printing process, and will not solidify rapidly after deposition [11]. If there is a free space for the moving nozzle between di erent printing areas, the formed part and nozzle will be deformed or damaged due to the adhesion of clay.…”

With the rapid development of the new manufacturing industry, 3D printing technology continues to make new technological breakthroughs, and new works emerge in the manufacturing, medical, construction, military, and other application fields. However, for ceramic materials, there are still many problems to be solved in 3D printing. In this study, a dual-scale lightweight interactive model based on lofted surface and periodic parameter curve embedding is proposed for ceramic 3D printing. Users can model and manufacture lofted surfaces with small-scale geometric textures. For the two closed curves entered by the user, the intermediate section sampling points are generated by interpolation between them, and the shape of the current surface is adjusted under ceramic 3D printing manufacturing constraints such as no support and path non-interference. complete large-scale surface modeling based on lofted surfaces. Then the straight line path between the sampling points is replaced by a periodic curve path, and the small-scale geometric texture modeling is completed by adjusting the period and amplitude of the curve function. Finally, each section sampling point is spirally connected layer by layer and directly generats a single continuous printing path and manufacture. The experimental results show that the tool provides users with sufficient modeling space and high efficiency of model generation and effectively generates G-code files with textured lofted surfaces that can directly print ceramic 3D. It can also avoid the collision between printer nozzles and printing models and can be directly used in 3D printing and manufacturing based on clay materials.
