Fatigue assessment of plain and notched 3D-printed PLA

Luca Susmel, The University of Sheffield

Additive manufacturing (AM) is a group of fabrication techniques through which materials are joined, usually layer upon layer, to make objects from three-dimensional virtual models. Owing to its unique features, this disruptive technology is set to transform the way designers across all engineering disciplines engage with manufacturing. Since this fabrication process affect the way materials behave under time-variable loading, it is evident that their fatigue strength must be studied in depth in order to effectively de-risk their usage in situations of engineering interest. By running appropriate experiments, the present study aims at investigating the influence of raster orientation and non-zero mean stresses on the fatigue behavior of plain and notched AM polylactide (PLA).
