摘要:
A method for making a three-dimensional object by means of layer-wise application and selective solidification of a pulverulent building material The method includes applying a layer of the pulverulent building material onto a build area by an application device The application device includes a recoating unit movable across the build area in an application direction. The method further includes solidification of the applied powder layer at positions corresponding to a cross-section of the object to be made, and repeating the steps of applying and selective solidification until the object is completed. The pulverulent building material to be applied onto the build area is heated locally by a radiant heater before being applied.
