Dielectric Properties and 3D Printing Fesibility of UV Curable Polymer Composites

摘要

In this study, UV curable polymer composites are investigated to explore their applicability in building the dielectrics with functionally graded material (d-FGM) using stereolithographic 3D printing technology. On the prepared test samples, several dielectric properties, i.e., permittivity, dielectric loss and breakdown strength, are characterized. 3D printing feasibility of the polymer composites are also investigated by measuring the viscosity and curing depth. Finally, influences of the ceramic filler's type, volume fraction and particle morphology on the dielectric properties and 3D printing feasibility are discussed.
