Abstract

The present invention is related to a method and apparatus for the volumetric fabrication of three-dimensional objects or articles from photoresponsive materials loaded with scattering particles, by adjusting the refractive index of said photoresponsive material () so as to match the refractive index of said scattering particles (), and/or using a light source emitting light of a wavelength longer than 630 nm, preferably in a range from 630 nm to 1050 nm, more preferably in a range from 650 nm to 900 nm.
