A invention disclosed a bio-mimicked three-dimensional laminated structure at least comprising a flexible lattice structure, which is characterized in that the flexible lattice structure comprises a plurality of particle units are uniformly disposed and evenly distributed in the X-axis, the Y-axis, and the Z-axis direction and evenly distributed as a lattice matrix of an array grid in an identical plane; wherein each of the particle units is an opened hollow shell or a close shell. The design eliminates the need for support structures and the subsequent post-processing required to remove them. A shell-shaped close cell bio-mimicked three-dimensional laminated structure bio-mimicking a sea urchin shape was introduced for the load-bearing structure application.
