PMSCs selecting microfluidic chip
- Advanced Manufacturing
The main outcome of the project was the design of a microfluidic system that can include a PC filter without impacting the microfluidic flow. The optimisation of VetCount has allowed the company to provide a smaller version and an optimised solution, including micropumps that will reduce the amount of material during their scale-up process, avoiding the amount of both raw and waste materials.
Through passing from manual milling and glueing to injection moulding, the consumption of energy per device has been reduced by 350%. That is linked directly to the company’s production costs. The moulding process development drastically increases the throughput, reduces human intervention (better reproducibility), as well as the number of steps for the fabrication. Compared to the current manufacturing process, tolerance will increase, and filters will be assembled easily, which results in a better and more robust microfluidic flow. Moulding enables the production of ~15,000-20,000 devices per month while keeping setup costs low and providing little inter-device variability.

Key success factors
The key success factor of this project was the efficient communication and cooperation with the KET TCs.
The company had a core design challenge, and that was to include filters into the microfluidic structure. The KET TCs helped solve that problem. The company is now testing the first of the tools that are based on the design generated by this project.
