Abstract:
An apparatus and a method of using the apparatus wherein a radiation emitter is positioned adjacent a sensor apparatus within a process chamber in a laser sinter system that emits radiation to the sensor apparatus and a calibration apparatus receives readings from the sensor apparatus to compare temperature sensings received from the sensor apparatus with set emission signals from the radiation emitter to adjust the temperature sensings to calibrate the sensor apparatus during the forming of a three-dimensional article. The calibration is done repeatedly during the build process of the three-dimensional article.

Abstract:
A method and apparatus for forming three dimensional objects by laser sintering that includes depositing the required quantities of powder for two successive layers on one side of the process chamber and simultaneously spreading the first layer while transporting the second layer quantity to the opposite side of the process chamber. The invention includes steps of parking the quantities of powder in sight of the part bed heater to pre-heat the powder and flattening the powder wave before the pre-heating step to improve pre-heat efficiency. This method and apparatus can result in reduction of the mechanisms, size, cost, and increase productivity of a laser-sintering device.
