Abstract
A method for providing control data for a generative layer construction device has a first step of accessing a data record which, at least for a partial region of an object cross section, specifies in which temporal sequence an energy beam bundle is to be moved in scanning lines over the places of this partial region to scan the buildup material. In a second step, the data record is changed such that in at least one of the layers for the respective partial region of an object cross-section, a check is carried out to determine whether the scan time required to scan the buildup material along a scanning line falls below a predefined minimum duration tmin and either a lower energy density of the energy beam bundle during scanning of the buildup material along this scanning line is specified and/or a wait time is specified before the energy beam bundle is moved along a further scanning line.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
