BYU’s Channel-Narrowing Technique for 3D Printed Microfluids

National Science Foundation

Laboratory: Brigham Young University (BYU)

Technology: Channel-Narrowing Technique for 3D Printed Microfluids

Opportunity: This patent-pending technology is available for licensing.

Details: This technology is a method of producing microfluidic channels by means of an innovative 3D printing process and a novel channel-narrowing technique. Researchers at BYU have demonstrated that a custom digital light processor stereolithographic (DLP-SLA) 3D printer and a specifically designed, low-cost custom resin can readily achieve flow channel cross sections as small as 18 μm × 20 μm.


Microfluidic devices are minuscule chips that can sort out disease biomarkers, cells, and other small structures in samples like blood by using microscopic channels incorporated into the devices. These chips are expensive and difficult to fabricate, and other 3D printers have not been able to create features smaller than 100 μm. This invention enables microfluidic structures to be created at dimensions of more than 5 times smaller than current alternatives, which will allow making complex microfluidics more easily and inexpensively.


  • Enables small flow channel fabrication
  • Relatively inexpensive

Applications: The invention will benefit DLP-SLA 3D printer manufacturers who want to access the microfluidics market. Applications include single-cell studies, separations, and biomarker analysis.
