1. A system for obtaining a photopolymerized prepolymer comprising:
an untreated material loading station for loading an untreated liquid material to be prepolymerized;
a closed loop conveyor carrying a plurality of material-receiving trays secured to the closed loop conveyor, arranged in sequence, and having open tops, the closed loop conveyor having a loading position on the side of the untreated material loading station and an unloading position on the side opposite to the loading position, wherein, when the material-receiving trays pass through the unloading position and changes direction of movement, the material receiving trays are turned into upside-down positions;
at least one prepolymerization station above the closed loop conveyor in a position that passes therethrough the material-receiving trays for irradiation of the untreated liquid material carried by the material-receiving trays by a dosed amount of light energy for photoprepolymerization, wherein the at least one prepolymerization station is configured to convert at least a portion of the material carried by the material-receiving trays into a prepolymerized material with a predetermined degree of prepolymerization that does not convert the material into a fully cured polymerized material; and
a prepolymerized material receiver located under the unloading position.
