Abstract: A method and apparatus for forming three dimensional objects by laser sintering that utilizes a broad area thermal vision system such as an infrared camera that can measure multiple temperatures across the target area and use that temperature data as feed back to a control system that both adjusts a zoned radiant heater system and adjusts scan speed and laser power to control temperatures across the target area.
