A radiant heating for heating the building material in a laser sintering device and a laser sintering device having such a radiant heating are described. The radiant heating has a sheet-like heat radiating element ( 113, 213, 313 ), which is characterized in that it is made of a material, that has a low thermal inertia with a thermal diffusivity of preferably more than 1.5·10 −4 m 2 /s and preferably has a thickness of 2 mm or less. |
