3D-Printed Material Destroys Pollutants

Apr-05-16 A 3D-printed material with active chemistry is not only the first of its kind, but could also be used to help trap and eliminate pollutants.

Developed by a team from American University, the 3D-printed material was made using a commercial printer, and takes the shape of a sponge-like matrix. To make the material chemically active, the team mixed a conventional thermoplastic with nanoparticles of titanium dioxide, which is known to break down pollutants when exposed to light. The plastic/nanoparticle mixture was then formed into a filament for use in standard, commercial 3D printers. When placed in a bit of polluted water, the material reacted with the natural light to instantly destroy the pollutants.
