Abstract
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 m2/s and preferably has a thickness of 2 mm or less.
