Abstract
Three techniques for the assessment of the fatigue response of AMed parts are compared: defect analysis and subsequent theoretical estimation of the fatigue strength with micro-CT, infrared thermography and ultrasonic fatigue testing. Experimental tests on AlSi10Mg specimens are carried out and proved that each investigated technique can be used for a rapid estimation of the fatigue response. The thermography technique and ultrasonic fatigue tests proved to be effective, evidencing the most critical defects. The fatigue response estimated starting from the defect analysis with micro-CT scans is mainly suggested for the inspection of large components.
