A method for providing control data to an additive manufacturing device includes a first step of accessing computer-based model data of a partial area of a cross-section of the object, and a second step of generating a data model of the sub-region, by specifying a solidification of the building material by at least one energy beam bundle along at least one solidification path. A plurality of solidification path sections are scanned at least twice with an energy beam bundle and the amount of energy to be introduced during the scanning is specified so that either the amount of energy introduced during the first scanning or a subsequent scanning is is too small to cause a solidification of the building material. In a third step, control data corresponding to the data model generated in the second step are provided for generating a control data set for the additive manufacturing device.

Additive manufacturing method with controlled solidification and corresponding device

Disclosed is a method for providing a control command set for an additive manufacturing device. The method includes providing a parameter set consisting of a number of parameters, and a construction rule, which is suitable for describing at least one section of the object by the parameter set geometrically as a number of linear or flat elements in space; generating a computer-based layer model of the section of the object by determining, for each layer, the position and shape of a cross-section of the section of the object within the layer, generating a control command set for an additive manufacturing device by which the production of the section of the object is implemented on the basis of the layer model.
