Abstract

This study uses the selective laser melting technology in additive manufacturing technology combined with high-frequency welding technology to prepare the artificial intervertebral disc. Static axial compression test, static compression shearing test, static torsion test and dynamic axial compression fatigue test were performed according to the ASTM F2346-05 standard specification. The static axial compression test results that the average compression stiffness of the artificial intervertebral disc is 543.81 N/mm. When the ultimate displacement is 1.854 mm, the ultimate force is 3053.10 N, and the static compression shear compression stiffness is 114.92 N/mm. When the ultimate displacement  is  4.363 mm, the ultimate force is 339.95 N. The fatigue test results show that the height of the artificial intervertebral disc changes from 8.35 mm to 8.25 mm.
