Abstract: A device for progressively building up an object from a light hardenable material. The device has a perforated build platform for the object. The build platform forms a build surface that faces a light source. The build platform and the light source are positionable relative to each other by computer control. The device is further configured for supplying the light hardenable material through the perforation of the build platform for building up the object. The invention enables the making of colored objects by stereolithography.
