consistent with previous studies using FEM simulations of the artificial vertebrae were similar to those of natural

This study demonstrated the potential of 3D-printed collapsing. We investigated the effect of infill parameters,
artificial vertebrae with bone-mimicked infill variations, including the infill densities of the hard and soft regions
fabricated through MEX, as an effective tool for evaluating and the volume ratio of the soft region, on the mechanical
