Tensile test of additively manufactured specimens with external notch removed via laser cutting in material extrusion

Tensile test of additively manufactured specimens with external notch removed via laser cutting in material extrusion

The specimens fabricated by material extrusion (ME)-type additive manufacturing (AM) have external notches because of their deposition mechanism. During tensile tests, accurate results cannot be obtained because the external notch causes stress concentration and induces fractures outside the gauge l...
