Abstract
In recent years, advancements in Additive Manufacturing (AM) technology have enabled the fabrication of complex shapes that were difficult to achieve with traditional manufacturing methods. Notably, in Fused Filament Fabrication (FFF) process, some research have been conducted not only on traditional planar layering but also on non-planar layering. By aligning the deposition layer in AM with a non-planar surface rather than a flat one, anisotropy can be reduced with increasing the contact area between layers, thereby improving strength and rigidity. In non-planar layering, the nozzle of an FFF-AM machine moves not only horizontally but also vertically during fabrication, which can construct accurate curved-surfaces that could not be achieved with existing planar layering.
On the other hand, a technique called computational design has been adopted for creating complex shapes, including in the design of modern architectural structures. In this study, the term “computational design” is regarded as "having the computer automatically design according to an algorithm conceived by the user." This can greatly reduce the modeling time for fabricated objects.
In this study, we apply the computational design to model cell structures that conform to a desired curved surface shape. The experiment is conducted to fabricate a test model and verify the effectiveness.
