Claim 0:
1. A method of printing a three-dimensional object, the method comprising:
supplying a print material to a plurality of ejector conduits arranged in an array, the ejector conduits comprising first ends configured to accept the print material and second ends comprising ejector nozzles, and the ejector conduits further comprising a transparent material and an absorbing material, a refractory material, or both;
advancing the print material in one or more of the ejector conduits of the array until the print material is disposed in the ejector nozzle of the one or more ejector conduits;
heating the print material positioned in at least one of the ejector nozzles using radiant energy, the radiant energy passing through the transparent material striking and heating the print material therein, the heating causing at least a portion of the print material to be ejected from the at least one of the ejector nozzles and onto a print substrate, and the transparent material refracting excess portions of the radiant energy that miss the print material therein and instead strike sides of the ejector conduits, so that the excess portions are redirected toward the print material within the ejector nozzles; and
repeating both the advancing the print material and the heating the print material to form a three-dimensional object on the print substrate.
