A poster and extended abstract have been presented at MicroTAS 2020 by Rob Hughes detailing work carried out with Harry and Andrea Diaz Gaxiola. The paper reference is available here: https://research-information.bris.ac.uk/en/publications/democratised-microfluidic-prototyping-using-a-3d-printed-click-an
The paper presents an introduction to work investigating negligible-cost, open-source microfluidic devices that are fabricated using 3D printer scaffolds printed using standard desktop size FFF machines (also known as MEX/FDM). These devices can then be connected together using a novel connector design to allow more complex devices to be developed.
It is demonstrated that a 5000 piece library of these inter-connecting devices would cost ~$0.50 to print, and can then be converted into finished microfluid channels using PDMS and items readily available in home and education settings.
The anticipation is for a journal paper to be completed in the near future (publication early 2021) that will ellaborate on the concept before pursuing further research streams in the future.
