A modern digital light processing technology to 3D print microfluidic chips

Conventional manufacturing methods such as soft lithography and hot embossing processes can be used to bioengineer microfluidic chips, albeit with limitations, including difficulty in preparing multilayered structures, cost-and labor-consuming fabrication processes as well as low productivity.

Materials scientists have introduced digital light processing as a cost-effective microfabrication approach to 3D print microfluidic chips, although the fabrication resolution of these microchannels are limited to a scale of sub-100 microns.

In a new report published in Microsystems and Nanoengineering, Zhuming Luo and a scientific team in , and chemical engineering in China developed an innovative digital light processing method.
