Description

A valve that uses pressure to pinch a channel closed. Three of them, 61, 91 and 122 µm wide, share one print for testing, each with four pinholes.

Developed at the Nordin Microfluidic and 3D Printing Lab, Brigham Young University.

Prints in a custom resin with NPS or avobenzone as the UV absorber.
