摘要：
Disclosed are an apparatus and a method for producing a three-dimensional object (3) by hardening layers (25, 26) of a powdery material at the points corresponding to the respective cross section of the object (3). The apparatus comprises a coating device (24) which can be displaced above a working field (5) and is used for applying the layers of the powdery material (27) within the working field (5). The coating device (24) is embodied with a rigid blade (21a, 21b) which is rigidly connected to the coating device (24). The coating device (24) is provided with a heater (20, 23) that is integrated at least in part into the coating device in order to preheat the powdery material (27), thus allowing the powder to be preheated while or before being applied as a layer, resulting in a reduction of the time required for constructing the three-dimensional object (3).
