3D printed microfluidic chip effective at 20 micrometers

Brigham Young University researchers developed printable resin and a new 3D printer to produce the lab-on-a-chip. Credit: BYU Photo Researchers at Brigham Young University (UT, USA) have developed the smallest viable microfluidic device produced to date. With a 3D printer they build themselves, the team utilized digital light processing stereolithography to produce the chip, which has flow channel cross sections of 18 micrometers by 20 micrometers. The work was published in Lab on a Chip. “It's not just a little step; it's a huge leap from one size regime to a previously inaccessible size regime for 3D printing,” author Adam Woolley,...
