Figure 6.

(A) Cross sectional image of a 125 × 54 μm channel (outlined in blue) printed with a polycarbonate membrane support. Area measures at 3 × 103 μm2 with a height of 15 μm and a corner to corner width of 250 μm. (B) Fluorescence image of fluorescein flowing through the channel highlighting that there is a continuous channel throughout the device. (C) Summary of measured channel area as compared to the designed channel area and the orientation for which the channel was printed in relation to the print heads. The channels were oriented parallel, perpendicular, and at a 45 deg angle to the direction of movement of the print heads. (D) Double serpentine channel designed at 150 × 54 μm with 14% RBCs in PSS flowing at 15 μL/min.
