Abstract Scope |
Tailored compliance is valuable to provide comfort and prevent unnecessary pain or strain on individuals in pain or recovering from injury by tailoring seats, footwear, braces, or prosthetics with variable compliance to accommodate for the pain or injury. Multi-material additive manufacturing enables the ability to manufacture meta-materials with tailored material properties, such as compliance. This study focuses on tailoring compression response by patterning an elastic matrix with stiff reinforcement material in quasi-2-D laminate patterns and 3-D spherical patterns. The composites are simulated using finite element analysis with hyperelastic constitutive models. Patterned parts were printed using Fused Filament Fabrication (FFF) of two different grades of TPU to verify and fit the computational model. These results will be used to design for variable compliance within a structure. |
