but can also accommodate sophisticated
features only accessible with advanced LOC fabrication
Fig. 3 a) Mixer design with through hole used for fluidic purposes. The
channels are 400 μm wide and 200 μm deep. b) Diffusion mixer image with
1 mM fluorescein and 1 mM rhodamine B flowed at 30 μl min−1
. c) Mixer
with through hole, measured at the same flow rate as b). d) Mixer with
through hole filled with micro beads, and measured in the same conditions
as b). White crosses highlight the position where the streams mix.

techniques. These aspects were shown possible, at a convenient
development cost of 0.57US$ per device, and for prototype
fabrication times under 30 min.
3D printed ULOC devices offer a breadboard for experimentation
that is compatible with fast and affordable prototype
optimization, which can exploit established LOC solutions.
