The invention relates to a method for repairing an ex-service gas turbine component (10) comprising the steps of: removing a damaged section (13) from said gas turbine component (10), manufacturing a 3-D article, which fits in said gas turbine component (10) to replace the removed damaged section (13), and joining said gas turbine component (10) and said 3-D article inserted therein. Reduced cost, an improved flexibility and productivity, and a simplified handling are achieved by removing the damaged section (13) in form of a cut-out section along a split line (14) as one single cut-out piece (15), measuring the cut- out piece (15) to obtain the actual non-parametric geometry data set of the cut-out piece (15), and manufacturing said 3-D article based on the said geometry data set of the cut-out piece (15).
