Infrared transparent constructs (e.g., infrared transparent windows) may be shaped as a dome (e.g., for an infrared detector system) and/or other desired geometries, such as portions of IR seeker domes. Electrically conductive tracing(s) may be printed in desired shapes and forms, e.g., in the form of EMI shielding, an FSS grid, an anti-static component, electrical connectors, etc., and integrated into the interior of the construct structure. The electrically conductive tracing(s) may be printed between layers of independent infrared transparent window components that are then engaged together to form a window preform. Additionally or alternatively, the electrically conductive tracing(s) may be printed between printed layers of infrared transparent ceramic or plastic material built up to form the window preform. Once formed, the window preform may be sintered, e.g., in an ultrafast high temperature sintering process (and optionally further treated) to produce the final infrared transparent construct.
