Abstract
Methods and apparatus comprising a dewetting phase and a polymerization liquid that are immiscible, and can be used for the formation of three-dimensional objects, wherein the method does not require a dead zone. Additionally, methods and apparatus that employ an optically transparent cooling apparatus to mitigate heat generated during the fabrication process, and the use of a mobile phase to provide a shearing interface to reduce interfacial adhesive forces.
