Abstract Scope |
Multi-zonal lattices can vary in density and topology throughout a single part to deliver uniquely tuned characteristics in different zones, allowing designers to specify characteristics required for their products at every millimeter. In this presentation, we dive into the technology behind how multi-zonal lattices are generated using Design Engine, Carbon's lattice design and analysis tool. First, we present a technique for generating infinite combinations of hybrid strut lattice cell types from a small set of primary cell types. The family of cell types can be expressed using a common low-order parameterization. Next, we demonstrate the construction of multi-zonal lattices from arbitrary combinations of user-specified cell types using a self-consistent interpolation method. This method guarantees the creation of struts that seamlessly join together while spatially transitioning between different cell types. Finally, we present experiments and simulations to showcase the spatially varying densities, large deformation mechanics, and potential applications of multi-zonal lattices. |
