Generative layer construction method having improved detail resolution, and device for carrying out the same

A method is disclosed and includes providing a first data set marking an object cross-section, determining whether the length of a connecting line undercuts a specified minimum dimension, generating a second data such that, in the event falling the minimum dimension is undercut, a position lying wit...

Zusammenfassung:	A method is disclosed and includes providing a first data set marking an object cross-section, determining whether the length of a connecting line undercuts a specified minimum dimension, generating a second data such that, in the event falling the minimum dimension is undercut, a position lying within an object cross-section on the connecting line is marked as a position not to be solidified or to which a reduced radiation to be supplied, and for a position lying outside of the object cross-section, positions of an object cross-section directly above or below that are adjacent to this position are marked as positions not to be solidified or to which a reduced radiation is to be supplied, and integrating the second data set into the control command set.
