Experimental fatigue dataset for additive-manufactured 3D-printed Polylactic acid biomaterials under fully-reversed rotating-bending bending loadings

Abstract

In this dataset, experimental fatigue testing results have been presented for the additive-manufactured 3D-printed Polylactic acid (PLA) biomaterials under fully-reversed rotating-bending loadings. For such an objective, a fused deposition modeling (FDM) 3D-printer was utilized to fabricate the standard cylindrical samples with different printing parameters in the horizontal direction. For the demonstration of printing parameter effects on the PLA fatigue lifetime, the nozzle diameters were from 0.2 to 0.6 mm, the extruder temperatures were from 180 to 240 °C, and finally, the printing speeds were from 5 to 15 mm/s. Then after 3D-printing of specimens, fatigue testing was performed on various samples under fully-reversed rotating-bending loadings. Then, the fatigue data were presented in tables through the high-cycle fatigue regime, under the load-controlled condition. For further works, these dataset tables could be used to draw the S-N (stress-lifetime) diagram, to find the fatigue strength coefficient and exponent.
