A component which was manufactured in a powder-bed production process, proceeding from a base plane. The component includes a finished part and a support structure. The finished part can be divided into an easy portion, which can be manufactured from the base plane without a support structure, and a difficult portion, which cannot be manufactured without a support structure. The support structure is connected to the easy portion by a first partial attachment and to the difficult portion by a second partial attachment. In order to simplify the subsequent processing, the first partial attachment has a plurality of connection points having an equivalent diameter of at most 1 mm.
