Herein, we report rapid 3D printing of architected barium titanate (BTO) composite structures with high resolution by using mCLIP. The BTO nanoparticles were surface functionalized to enable stable dispersion in poly(ethylene glycol) diacrylate (PEGDA). Resins with up to 30 wt% of functionalized-BTO (f-BTO) nanoparticles were prepared and printed continuously to yield a variety of architected structures with unprecedented longitudinal printing speeds of up to ~ 20 μm/s. The architected structures were tested with a customized piezoelectric characterization setup and demonstrate effective piezoelectric coefficient d33 up to 30 pC N-1 and piezoelectric voltage constant g33 up to 460 mV mN-1 which is comparable to other reported work. This work not only enables the rapid 3D printing of architected piezoelectric structures with tailorable properties via compositional and structural modifications, but also intrinsically enlightens its potential capability for eco- and biocompatible applications.
