The bending strength of products created by a 3D printer was measured by changing printing speed (300 mm/s,200 mm/s and 100 mm/s) and layer height (0.2 mm and 0.1 mm) in this study. The bending strength was highest in order of 200 mm/s, 100 mm/s and 300 mm/s. The bending strength exhibited less variation at a layer height of 0.1 mm compared to 0.2 mm, with the variation further decreasing as the printing speed decreased. Based on the above results, it is considered effective to reduce the layer height and set the printing speed appropriately to manufacture products with high strength and fast printing performance.
