Microfluidic devices

Our work in micro-scale printing is motivated by exciting opportunities for using optical 3D printing in biological applications. Microfluidic devices are used in chemical and biological applications to perform fluid reactions using internal channels on the order of 1-1000 microns.[] Typical microfluidic devices are generated by using top-down lithography techniques, but additive manufacturing holds exciting potential in this field for fast turnaround, complex internal features, and multimaterial structures. In particular, we are exploring printers such as the Formlabs Form 1 and the Stratasys Objet500 Connex to create microfluidic devices. We have demonstrated the first 3D printed microfluidic valves made from both single and multiple materials (Figure 18-10).[] Similar to integrated circuits, microfluidics hold potential for miniaturizing biological and chemical reactions for a variety of medical and product devices.
