    Abstract: The invention relates to a method for preparing simulated samples for non-destructive testing of metal materials, which can carry out reverse batch copying of cavity-type defect samples, specifically: obtaining metal samples with natural and real cavity-type defects; using high-resolution X-ray industrial CT scans the sample to obtain relevant information about cavity defects in the sample; using 3D laser printing method to batch prepare new samples with combined defect characteristics that meet defect consistency; using high-resolution X-ray industrial CT to obtain the cavity defects prepared by printing are reviewed, inspected, and evaluated with the original cavity defects to verify that the printed samples meet the requirements of cavity defect consistency; save cavity defect information, scanning parameters, powder composition and printing process parameters.
