Selective laser sintering of a powder used as a rapid prototyping process comprises adding the powder to an encapsulated chamber, and forming a powder cake

摘要

Process for selective laser sintering of a powder comprises adding the powder to an encapsulated chamber, and forming a powder cake. The encapsulation is heated so that a temperature distribution is adjusted in the encapsulation. The temperature decreases from the regions of the encapsulation which border the sintered surface of the cake in the direction of the base of the chamber. An Independent claim is also included for a device for selective laser sintering of a powder. Preferred Features: The temperature decreases in a linear manner. The encapsulation comprises a heater which is controlled in such a way that the temperature of the chamber base corresponds to each point of the temperature of the region of the chamber wall.
