A Preparation of the Ti64 slurry ink. B DIW of the Ti64 slurry ink into a pre-defined 3D structure and the microstructure evolution B1 without and B2 with external shear stress. C Photocrosslinking to induce the solidification of the printed structure. D Multi-step heat treatment to remove unnecessary components and sinter Ti64 powders. E Representative applications of the printed porous metal structure.
