Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, ...

(a) Schematic of the multi-material one-step printing process, demonstrating the sequential switching of three different resin tanks during printing to achieve composite structures in a single step.

Researchers at BYU are the first to 3D-print a viable microfluidic device small enough to be effective at a scale much less than 100 micrometers. Microfluidic devices are tiny chips that can sort out ...
