| Abstract Scope |
Thick-folding origami-based mechanisms have been adapted for additive manufacturing, reducing part count and fabrication complexity. Within such mechanisms, rigid-foldable designs require high stiffness in panels and low stiffness in surrogate folds, motivating spatially varying material properties. Voxel-based design enables multi-dimensional functional grading based on distance fields; however, the choice of distance metric can significantly influence gradient formation and, consequently, mechanical performance. Minkowski distance is a generalized distance formula that reduces to create other types of distances such as Manhattan, Euclidean, and Chebyshev distance within multiple dimensions. Each of these distances has different impact on the resultant gradient and thus, the distribution of the material properties. This work expands upon the extant work to encompass higher-order dimensions of space and reveals the extent to which higher-order voxel-based design can reduce stress. This enables more complex mechanism design with refined gradients and lower possibility of interfacial failure at point-like interfaces. |
