| 摘要 |
The invention relates to a method for the manufacture of a three-dimensional molding ( 29 ), wherein the molding ( 29 ) is generated from a solidifiable powder material by consecutively solidifying individual layers through the effect of radiation ( 27 ), while generating a new layer by exposing traces that are arranged adjacent to each other to radiation, wherein, in order to form an overhang region ( 47 ), a contour trace ( 49 ) is formed on a coherently solidified region and on a powder material ( 17 ) that has not solidified yet, the contour trace ( 49 ) is adjusted to an outer contour at least in the region of transition from the solidified region to the powder material ( 17 ) that has not solidified yet, and the at least one further contour trace ( 49 ') adjusted to the outer contour is formed of non-solidified material ( 17 ) while comprising a high overlapping degree in relation to the previously formed contour trace ( 49 ).
