Abstract

3D Printing of Porous Membrane Integrated Devices

Rosanne Guijt, Professor, Smart Sensing, Deakin University

The integration of chemical functionalities in microfluidic devices can be accomplished by the combination of different materials. 3D printing has readily been proposed as alternative for manufacturing of fluidic devices, in particular for small scale production. Resin-based printers are most suitable for printing small features, 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, extraction of DNA and the detection of iron from soil.
