Online repair method for defect model data in additive manufacturing forming process

The invention relates to the technical field of additive manufacturing, in particular to an online repair method for defect model data in an additive manufacturing forming process, which comprises the following steps of: performing model data adjustment on all to-be-repaired additive layers between a starting layer and an ending layer of an additive manufacturing model by adopting a corresponding defect repair strategy; specifically, a local model data deleting function, a local model data adding function and a local model data modifying function are added in additive manufacturing forming control software, and the functions of increasing and decreasing local spatial data and modifying technological parameters of local forming data can be directly achieved on the basis of a current printing package. Compared with the prior art, the method has the advantages that defects and quality problems existing in the forming process can be quickly repaired, the processing time is shortened, the dependency on technicians
