Title: Controlling Material Reactivity Using Architecture

3D-printing methods are used to generate reactive material architectures. We observed several geometric parameters in order to influence the resultant flame propagation velocity, indicating that the architecture can be utilized to control reactivity. Two different architectures, channels and hurdles, are generated, and thin films of thermite are deposited onto the surface. Additionally, the architecture offers a route to control, at will, the energy release rate in reactive composite materials.
