Miniaturization is a key aspect for many technological applications and the use of
microreactors is an excellent solution for the intensification of chemical processes for a variety
of applications. However, standard microfabrication requires large facilities and intricate
fabrication protocols, and consequently it is not easily available, generally resulting in high
production costs. Herein, we present a very cheap, fast and easy microreactor design for
photocatalytic applications based on direct fused filament 3D printing as a facilitating and widespread technology. The microreactor consists of three bodies directly printed in ABS
(Acrylonitrile Butadiene Styrene): a main body with a serpentine microchannel pattern where the
photocatalyst is placed, a top holder with a transparent polymer window, and a base to clamp the
parts. Several microreactor units were coated with TiO2 doped with Cu (2.4 wt.%) nanoparticles
synthesized by FSP (Flame Spray Pyrolysis) and tested for the photocatalytic degradation of two
water pollutants showing excellent performance. [--]
