Abstract

Disclosed herein is an apparatus (10) for post-curing an object (12). The object (12) comprises polymerised photohardenable liquid. The apparatus comprises an enclosure (14) for receiving therein the object (12). The apparatus (10) comprises at least one actinic light source (16) for generating actinic light and at least one light diffusing element (18) cooperatively arranged with the at least one actinic light source (16) to generate diffusely recirculated actinic light within the enclosure (14). The apparatus (10) comprises an actinic light detector (20) configured to generate a signal (22) indicative of a quantity of diffusely recirculated actinic light within the enclosure (14). Also disclosed is a method for post-curing an object.
