Lab-on-a-chip (LOC) technology is widely regarded as the answer to a variety of global healthcare challenges. While many critical challenges are faced by clinicians and researchers in resource-limited parts of the world, the so-called LOC “solutions” are predominantly devised and developed by well-funded labs in the developed world using equipment, expertise and resources inaccessible to most. It is for this reason that the uptake of many potential LOC solutions is often limited, due to expense or a failure to account for local practical complications.
Our aim is to put LOC fabrication technology into the hands of researchers & clinicians most familiar with these challenges, by democratising the process & resources required for fabrication and prototyping. This will allow anyone in the world to experiment with LOC technology, no matter their financial resources.
Micofluidics is the fundamental technology underpinning LOC technology. As such, we have tried to produce reliable, low-cost microfludic fabrication technology that could be used by anyone in the world with limited resources available to them, in order to empower researchers, clinicians and students to find unique solutions to these global challenges.
Using only commercially available FDM printers (Ultimakers from CREATE Education) and accessories, we have developed a novel 3D-printed, interconnecting scaffold design, simple fabrication method, and open-access resources that can be used to quickly produce reliable microfluidic channels at a nearly negligible expense and with no specialist equipment or resources.
We were able to demonstrate that this technique could be used to reliably produce working microfluidic devices and demonstrated that the printing resolution could be pushed to a limit of 100 microns using standard FDM printing of thermoplastics.
Extreme cost-saving, speed and reliability of microfluidic fabrication. The low-cost and low-resource approach makes it suitable not just for research but also for education. This work could be revolutionary in helping doctors and medical researchers to create the tests they need to for their patients.
"This project was not possible without the Ultimaker thermo-plastic printer and the high standard of printing allowed us to achieve very high resolution. "
