1. A method for manufacturing a component starting from a base plane which extends in an X direction and a Y direction and defines a vertical Z direction, comprising:
providing a model of a finished part;
determining an easy partial section of the finished part to be produced starting from the base plane without a support structure and a difficult partial section of the finished part which is spaced apart from the base plane and cannot be produced without the support structure;
determining the support structure, which is to be connected to the easy partial section via a first partial attachment and to the difficult partial section via a second partial attachment,
manufacturing the component in a powder-bed production process in which local melting of a powdered material is accomplished by a beam,
forming connection point extensions via the powder-bed production process, each connection point extension extending from the support structure,
forming a multiplicity of connection points, wherein each connection point connects a respective connection point extension to the finished part,
wherein the first partial attachment is formed by at least one bridge element having a width of at most 2 mm, and further formed by the multiplicity of connection points, each connection point having an equivalent diameter of at most 1mm, and each equivalent diameter being smaller than a width of a connection point extension leading to the respective connection point,
wherein in each partial attachment a total of cross-sectional areas of the multiplicity of connection points taken at the respective equivalent diameters corresponds to at least 5 times a total of cross-sectional areas of the at least one bridge element, and
wherein when forming the multiplicity of connection points, a beam center forming a respective connection point extension within a respective layer maintains a first separation distance from a portion of an adjacent partial section that is within the respective layer and a beam center moving along a partial section within a respective layer maintains the first separation distance from a respective connection point extension that is within the respective layer.
