ADDITIVELY MANUFACTURED METALLIC CELLULAR STRUCTURES
… were manufactured using an AM technique called laser powder bed fusion (L-PBF). Two L-PBF build parameters, hatch angle and build orientation, were investigated and optimized to manufacture defect-free solids. The optimized build parameters were used to manufacture different cellular structures, …
