Analysis of the resistance to crack propagation in SENT test specimens printed in ABS using parallel or crossed filaments between layers

Additive manufacturing techniques continue to develop and cover all industrial fields. However, the performances of aspect mechanical behavior parts obtained by this process remain be mastered are still subject current research works. Among these performances, one corresponding resistance propagation cracks. In order improve very interesting property in various fields, it is desirable master understanding crack type structure 3D printing. The objective paper analyze understand effect adopted raster angle on SENT specimens FDM ABS (Acrylonitrile-Butadiene-Styrene). Two approaches were developed: experimental determine critical stress intensity factor KIC other numerical predict possible paths propagation.
