1. A three-dimensional (3D) printer system comprising:
a building platform defining a building plane;
a material transport unit having a carrier film;
a nozzle configured to eject a photopolymer resin onto the carrier film to create one or more material layers of the photopolymer resin on the carrier film;
a light engine comprising a light source configured to provide light, the light engine associated with an exposure field configured to expose the light toward at least a portion of the building plane;
a first drive mechanism configured to drive the material transport unit to transport the one or more material layers of the photopolymer resin toward the exposure field;
a second drive mechanism configured to move the light engine or the building platform relative to one another along a path parallel to the building plane; and
a first control unit configured to provide instructions to one or more of the first drive mechanism and the second drive mechanism to optimize movement of one or more of the material transport unit and the light engine relative to the building platform while at least a portion of the one or more material layers is on the building plane within the exposure field.
