Abstract
3D printing is a relatively new manufacturing process that involves layers of material being repeatedly applied until a complete geometry is produced. 3D printing is incredibly flexible in that it allows for multiple different print orientations and speeds to be utilized. Since 3D printing is still a relatively new manufacturing process, very little is known about how print orientation and speed affect the performance of the resulting parts. One such performance measure is a material’s ability to resist failure while being repeatedly subjected to stresses of varying magnitudes. This testing is very useful for engineers since it allows us to plan around the inevitability of failure. In our research, we were interested in analyzing how print orientation and speed affected the fatigue performance of 3D printed Acrylonitrile Butadiene Styrene (ABS) samples subjected to varying cyclical stresses. We did this by testing two different print orientations and two different print speeds for a total of four different control groups. Of the two print orientations, one group was printed so that the layers of ABS laid down by the printer formed a series of parallel rods that collectively formed our sample. The other group was printed so that a series of concentric circles would extend vertically to create our sample. The two print speeds used in this project were 2,400 mm/sec and 3,600 mm/sec. We anticipated the first print orientation printed at 2,400 mm/sec to be the strongest, however we found very little difference in performance between these control groups.
