Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

This study demonstrates binder‐free laser powder bed fusion (PBF‐LB) of 8 mol% yttria‐stabilized zirconia (8YSZ) using a femtosecond laser and a triangular scan strategy that controls heat accumulation by varying scan‐vector length. Laser power (31–52 W), scan speed (100–500 mm s...
