METHODS ---------- Silica-filled and standard photopolymer samples were fabricated using a Form 2 Stereolithography 3D printer. These were then tested using a broadband THz time-domain spectroscopy system to characterise the absorption coefficient and refractive index of the samples. The time domain data was then fourier transformed and the refractive index and absorption coefficient was determined from 1-4 THz.
