It is important to note that the eggs are on the lower limit of our staircase sorting device (25 µm), and it is possible that broken eggs can pass through, especially if force is applied to push the water through. The capturing of broken eggs can be improved by elongating the last 25 µm channel, which currently is only 500 µm in length, to give smaller particles more opportunities to be blocked by the roughness of the channel. It is also possible that in the future, consumer-grade 3D printers will reach a Z resolution below 25 µm.
