Utilized a commercially available video projector for mask patterning.
Developed a process completed in under 30 minutes.
Quantified field of view and resolution capabilities of the video projection system.

Main Results:

Successfully fabricated critical microfluidic components including junctions, straight, and curved channels.
Demonstrated the production of three diverse microfluidic devices: droplet generation, gradient generation, and a neuro-engineering device.
Achieved precise alignment of two masks for a compartmentalized microfluidic chip.

Conclusions:

The described video-projection-based method offers a rapid, low-cost, and accessible solution for microfluidic mask prototyping.
This technique is suitable for various microfluidic applications, including complex devices for research and education.
