Abstract
The disclosure provides systems for 3D printing. A 3D printer system includes one or more sources of actinic radiation characterized at least by a powered state and an unpowered state. A resin enclosure is transmissive to the actinic radiation. A temperature control system thermally communicates with the resin enclosure and maintains the resin enclosure at a predetermined sub-ambient chilled state. A control circuit is in electrical communication with the sources of actinic radiation and the temperature control system. The control circuit includes first non-transitory logic to switch the sources of actinic radiation to the powered state when one or more threshold criteria is satisfied including a requirement the temperature control system is in a predetermined state causing the resin enclosure to be below a temperature. A second non-transitory logic switches the sources of actinic radiation to the unpowered state when one or more threshold criteria is not satisfied.
