摘要： A thermal management system is provided to control the preheating and cool down of a removable build chamber in a laser sintering system. A thermal management station controls preheating of a removable build chamber to heat the chamber to a temperature at or near the operating temperature of the laser sintering system. After insertion into the laser sintering system and completion of a build the thermal management station controls the cool down of the part cake within the removable build chamber after the chamber has been removed from the laser sintering system.

摘要： 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 (160) to pre-heat the powder and flattening the powder wave (184) 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.

摘要： An apparatus and a method of using the apparatus wherein a radiation emitter (140) is positioned adjacent a sensor means (142,144,145) within a process chamber (102) in a laser sinter system (100) that emits radiation to the sensor means and a calibration means receives readings from the sensor means (142,144,145) to compare temperature sensings received from the sensor means with set emission signals from the radiation emitter (140) to adjust the temperature sensings to thereby calibrate the sensor means during the forming of a three-dimensional article. The calibration is done repeatedly during the build process of the three-dimensional article (Fig. 1).

摘要： The invention is a method for controllably cooling at least a portion of a part-cake from a laser sintering system to minimize cool down time, maximize throughput, and minimize thermal gradients within the part-cake. The method generally comprises forming one or more thermal transfer channels within the part-cake. The thermal transfer channels can include ducts and cooling fins in the part-cake surrounding the formed part. The method can further comprise removing unfused powder from the ducts and introducing cooling media into the ducts. The invention also includes a part-cake having thermal transfer channels formed therein and a laser sintering apparatus comprising a part-cake containing cylinder having permanent fittings therein for receiving terminal portions of thermal transfer channels formed in the part-cake.
