1. A system for creation of one or more three-dimensional shaped bodies, the system comprising:
a building platform;
a material support having a permeable region, wherein the material support is shaped to receive polymerizable material, and wherein the permeable region is permeable to electromagnetic radiation;
a plurality of radiation units comprising at least one first radiation unit and at least one second radiation unit,
wherein the at least one first radiation unit comprises at least one light source operative to direct a first irradiation field toward the permeable region of the material support to cure the polymerizable material within the material support to form layers of a three-dimensionally shaped body on the building platform;
wherein the at least one second radiation unit comprises at least one heating element operative to direct a second irradiation field toward a region of the permeable region of the material support that is transparent to the first irradiation field of the at least one first radiation unit to cause radiant heating of the material support.
