Abstract Millions of patients each year are impacted by critical‐size bone tissue defects, the repair which involves inflammation and formation new tissue. In this study, a fractal biomimetic design for 3D‐printed scaffold that combined 3D printing with high‐energy plasma tantalum alloy fabrication, enabling easy production on an industrial scale is proposed. The bionic leverages principles geometry, employing self‐affine patterns random fractals to attain surface scaffolds. This approach aimed emulate dimensions observed in natural structures closely. While roughness implants plays critical role restoration outcomes, findings suggest incorporating dimension may hold greater significance than mere roughness. A rat skull‐defect model utilized assess osteogenic potential three scaffolds, photoacoustic technology first employed long‐term, situ monitoring physiological signals during process. Results from both cell animal experiments demonstrated scaffolds offer notable advantages over surface‐modified experimental results showed group manifested better bone‐promoting
