its entirety, the printing process utilized minimal support like layer boundaries or warping. The 3D-printed bone plate
for easy removal and less powder waste. and filler had a smooth surface with low roughness (Figure

plate, and filler (Figure 13d) and filler (Figure 13b) revealed clear porous
structures with a bright surface and good connectivity.
