3-D Printed Honeycomb Structure

Caption: This is an optical photograph of a translucent hexagonal honeycomb printed using the baseline epoxy ink with ~1 vol.% carbon fibers added for visualization. The aligned black fibers are clearly visible within the cell walls and throughout the structure. The complete structure is 3 mm high and 30x40 mm in area, with cells that are 6 mm from wall to wall. This was printed with a 200 μm nozzle at ~30 mm/s. The darkening at the nodes is due to the larger volume of material causing slightly elevated temperatures during the curing cycle.
