UV photolithography is one of the most widely used microfabrication techniques for LOAC applications. Conventional UV light sources based on high-pressure mercury lamps are relatively expensive and provide broad-band illumination with intensity that often changes with time. We designed and built a monochromatic UV flood source based on a small array of high-power 365 nm UV LEDs. The light source provides uniform and collimated UV-illumination over a large target area and is very well suited for the fabrication of thick (>50 µm) relief patterns with SU8 photoresists for rapid prototyping of microfluidic devices. In addition, the LED light source is very stable, inexpensive to build, and near maintenance-free. I will also present several examples of how laser cutting and 3D printing can be used for the fabrication of LOAC microdevices with features in an intermediate range of scales (0.1 – 10 mm) and how these two fabrication techniques can be combined with UV photolithography.
