The present application describes a system for curing moldable material. The system comprises an energy source, a mold, and/or other components. The mold comprises internal mold surfaces forming a mold cavity. The mold is formed from one or more materials configured to absorb electromagnetic radiation emitted by the energy source. The mold has a hot zone and a cold zone. The hot zone and the cold zone have the one or more materials thereof comprising at least one different physical characteristic so that the hot zone and the cold zone absorb the electromagnetic radiation at different rates and/or in different amounts. The hot zone absorbs more electromagnetic radiation than, and/or electromagnetic radiation faster than, the cold zone.
