Abstract
Various embodiments may include a method for the generative manufacturing of a component on a building platform comprising: applying particles of a building material layer by layer to the building platform and then to the component under construction; fusing the applied particles with an energy beam; and heating the component under construction with a heating device associated with the building platform. A reference temperature Tr for each layer produced and a tolerance range for the reference temperature Tr are defined. A heating power of the heating device is lowered as sequential layers are fused to the extent that the tolerance range for a reference temperature Tr is maintained in a last layer produced.
