Continuous flow photochemical synthesis of metal–ceramic composite microparticles

Abstract

We developed a UV-assisted microfluidic system to synthesize FeCrAl–Al₂O₃ composite microparticles for additive manufacturing. The system ensures precise particle size, morphology, and elemental distribution control. Increasing the dispensing pressure while keeping the oil flow rate constant resulted in larger microparticles. Laser fusing revealed FeCrAl and Al₂O₃ phases, showing their potential as feedstocks for 3D printed heterogeneous materials such as FeCrAl/Al₂O₃ bi-phase materials.
