Pressurized photobonding for 3D-printed inertial and droplet microfluidics.

ABSTRACT: Microfluidics has transformed scientific and industrial applications by leveraging fluid dynamics at small scales, yet limitations in fabrication techniques continue to impede scalability and design flexibility. This study introduces a novel 3D-printing-based fabrication method, termed "press-cure", which enables the creation of microfluidic devices with high resolution, strong bonds, and solvent resistance using commercially available stereolithography printers. By applying uniform pressure and ultraviolet curing to 3D-printed components, the press-cure method achieves sub-100-micrometer channel dimensions, robust bonding, and structural fidelity under pressures exceeding 300 psi. We demonstrate the versatility of this technique through several microfluidic applications, including scalabl
