1. A photopolymerized prepolymer production system, the system comprising:
a conveyor configured to move material from a loading area to an unloading area;
a prepolymerization chamber positioned proximate the conveyor, the prepolymerization chamber having:
a first prepolymerization station located within the prepolymerization chamber, the first prepolymerization station including a first light source configured to irradiate material at a first intensity level as the conveyor moves the material past the first prepolymerization station, wherein the material comprises an untreated liquid material before the separate conveyor moves the material past the first prepolymerization station, and
a second prepolymerization station located within the prepolymerization chamber proximate the first prepolymerization station, the second prepolymerization station including a second light source configured to irradiate the material at a second intensity level as the conveyor moves the material past the second prepolymerization station, wherein the prepolymerization chamber is configured to convert at least a portion of the untreated liquid material into a photopolymerized prepolymer material with a predetermined degree of prepolymerization that does not convert the material into a fully cured polymerized material, and wherein the prepolymerization chamber is configured to automatically increase the first intensity level when operation of the second prepolymerization station is halted and to automatically increase the second intensity level when operation of the first prepolymerization station is halted; and
one or more processors configured to control operations of the conveyor, the prepolymerization chamber, or both, wherein the one or more processors are configured to alter operations of the conveyor, the prepolymerization chamber, or both, in response to a detected system event.
