Provided herein is a method of making a clear or translucent object by additive manufacturing, comprising (a) providing a clear or translucent light polymerizable resin, the resin comprising: (i) light-polymerizable monomers, prepolymers, or a combination thereof; (ii) a photoinitiator; and (iii) a polysubstituted linear polyacene ultraviolet light absorbing compound which compound is polysubstituted with bromo, chloro, &#x2014;Se&#x2014;R', &#x2014;S&#x2014;R&#x2032; or combinations thereof, where each R&#x2032; is independently selected from alkyl, aryl, and arylalkyl; and then (b) producing by stereolithography with ultraviolet light a clear or translucent object from said light polymerizable resin.

Production of light-transmissive objects by additive manufacturing

An integrated additive manufacturing system includes: (a) at least one resin supply (); (b) a plurality of additive manufacturing machines () on which parts may be produced, each of the additive manufacturing machines () operatively associated with the at least one resin supply (); and (c) at least one peripheral machine () operatively associated with each of the additive manufacturing machines and the at least one resin supply.
