Claim 10:
11. A method for evaluating the quality of a component produced by an additive sintering and/or melting method, comprising the steps of:
providing an additive sintering and/or melting equipment unit for manufacturing a component for an aircraft engine;
providing a detection device, which is configured and arranged to record spatially resolved color values, which each characterize the temperature of the component at an associated component location during sintering and/or melting of the component; and
providing a computing device, by which:
a first data set can be generated from the spatially resolved color values;
a second data set can be provided, with the second data set comprising spatially resolved color values corresponding to the first data set, said color values each characterizing the temperature of a reference component at an associated reference component location during sintering and/or melting of the reference component;
any difference between the first data set and the second data set can be determined; and
at least the quality of the component can be evaluated on the basis of the difference between the first data set and the second data set;

applying a layer of material at an associated component location of a component via additive sintering and/or melting method;
providing a first data set, which comprises spatially resolved color values, which each characterize the temperature of the component at an associated component location during the sintering and/or melting of the component;
providing a second data set, which comprises spatially resolved color values corresponding to the first data set, the color values each characterizing the temperature of a reference component at an associated reference component location during the sintering and/or melting of the reference component;
determining a difference between the first data set and the second data set; and
evaluating the quality of the component on the basis of the difference between the first data set and the second data set,
wherein the first data set and/or the second data set are/is created from measured values that are determined by using a high-resolution detector and/or an optical thermography method.
