Figure 3
The image presents three graphs labeled (a), (b), and (c). Graph (a) shows the relationship between average density, represented as a percentage, and scan speed in millimetres per second, with different symbols indicating varying hatch spacings measured in micrometres. Graph (b) depicts average density against laser power in watts, also using various symbols for hatch spacing. In graph (c), average breaking elongation percentage and average relative density percentage are plotted against energy density measured in joules per cubic millimetre. This graph includes bars for average relative density and average toughness, with distinct markers for average max stress and average breaking elongation. The axes are clearly labeled, with the ranges and increments specified.Density variations of LB-PBF concerning (a) hatch distance and scan speed, (b) hatch distance and laser power and (c) energy density versus average relative density, breaking elongation, average max stress and average toughness
