Abstract

3D Printing of Porous Membrane Integrated Devices

Rosanne Guijt, Professor, Smart Sensing, Deakin University

The integration of chemical functionalities in microfluidic devices is mostly accompanied by the combination of different materials.  3D printing has readily been proposed as manufacturing alternative for traditional approaches, in particular for small scale production. In particular in resin-based printers, however, the combination of different materials remains a challenge. This presentation focuses on the development of resins for digital light projection 3D printing of porous materials, and their integration into fluidic devices by resin exchange and using greyscale masks. Applications of the devices include phase separation, chemotaxis, electroextraction of DNA and the detection of iron from soil.
