Abstract Scope |
Fiber-reinforced polymer composite parts with continuous fibers embedded along bespoke spatial paths for a specific mechanical loading are shown to have superior stiffness and strength. We had presented a vat photopolymerization-based machine that can steer a single fiber along a spatial path within the layer-by-layer process. Here, we report an advancement that automates simultaneous spatial steering of multiple fibers. For this, we use permanent magnets that hold and steer the fibers in different directions with actuation provided by a cylindrical array of electromagnets. The method, machine, and process of actuating electromagnets along with the 3D-printed composite parts are presented. |
