摘要: A broad range of synthetic trabecular-like metallic lattices is 3D printed in Ti-6Al-4V by SLM. The aim to propose new conceptual types implant structures for superior biomechanical matching and osseo-integration: bone. Systematic evaluation then carried out: (i) their accuracy characterised using HR X-ray tomography, assess deviations from the original geometrical design intent (ii) mechanical properties—stiffness strength—are experimentally measured compared. Finally, this knowledge synthesised a framework form maps, define processing conditions bone tailored substitutes. criteria emphasise (a) stiffness matching, (b) preferred pore structure ingrowth, (c) manufacturability, (d) choice inherent materials properties durable implants. power demonstrated prototype spine fusion device.
