Figure 5.

High-resolution, high aspect ratio channels. a) Oblique-view micrograph of 1 pixel (27 µm) wide, 1 mm tall channels separated by 2 pixel (54 µm) wide walls. The channels (white arrow) are printed using the Asiga Pico2 HD Printer and subsequently filled with blue dye to demonstrate channel clearance. Errors in CAD slicing (black arrow) by the printer’s STL file conversion software resulted in omission/addition of pixels, which led to inaccuracies in the printing of some wall structures but had no detectable effect on the overall functionality of the device. b) Top-view micrograph of 1 pixel wide channels (white arrow) filled with blue dye.
