AI model ScaffoldForge designs 3D printed bone scaffolds in 12 seconds

Researchers unveiled ScaffoldForge, a generative AI model that turns target structural properties into a complete 3D printed bone scaffold geometry in about 12 seconds, versus roughly 8,400 seconds for topology optimization. Simulated compressive strength reached 56.6 MPa, 8.2% above TO; no scaffolds were printed or lab-tested.

• Design generation takes ~12 seconds versus ~8,400 seconds for topology optimization
• Estimated compressive strength of 56.6 MPa is 8.2% above TO and 6.6% above TriTopo-LGDM
• Trained on 250 scaffolds, including 50 real ones with measured mechanical data
• Fit error stayed within 1 mm tolerance across 20 spine CT cases
