1. A system for printing a three-dimensional object comprising a plurality of layers, the system comprising:
a base plate comprising a first heat source;
a substrate attached to the base plate;
a printing head operable to dispense ink on the substrate to form the printed object comprised of the plurality of layers, wherein the ink comprises a carrier liquid containing a dispersed material to be deposited during printing;
a second heat source located above the substrate operable to emit heat onto an upper layer of the plurality of layers;
a first temperature sensor configured to measure a temperature of the base plate;
a second temperature sensor configured to read a temperature of the upper layer of the plurality of layers; and,
a controller communicatively coupled with the first and the second heat sources, the first and second temperature sensors, and the printing head, the controller configured to:
adjust the first and second heat sources to control temperatures of the substrate and to apply heat to each respective upper layer, as the upper layer is being printed, to evaporate the carrier liquid according to predetermined functions, said predetermined functions comprising:
at lower heights below a predetermined printing height of the upper layer, maintaining a higher temperature of the upper layer compared to higher heights at and above a predetermined printing height of the upper layer; and
maintaining the temperature of the upper layer substantially constant versus the printing height of the upper layer, from above the predetermined printing height of the upper layer.
