Abstract

Additive manufacturing is becoming increasingly more popular and efficient. One drawback is the possibility of interlayer discontinuities forming in the material. A non-destructive technique utilizing the changing resistivity of the material as discontinuities appear was used to detect those discontinuities and was verified through additional testing of manually added through-thickness discontinuities. This technique has been proven to be useful in understanding fatigue crack growth of conventional metal and composite structures. Experimental investigation of fatigue in steel with an edge notch has been performed using these techniques to understand source and location of crack formation and growth in conventional material. Application of this technique on additively manufactured metal structures will cut quality assurance costs and help improve 3D printing technology by pinpointing errors.
