Design Principles

"Biomimicry in scaffold design should consider both structural integrity and biological functionality, achievable through advanced additive manufacturing."

This breakthrough allows for the creation of patient-specific bone implants that are not only structurally sound but also promote better integration with the body due to their porous nature. It opens avenues for more effective bone regeneration and reduces the need for traditional bone grafts.

What This Means for Your Design

Scientists can now 3D print ceramic bone implants that are very porous (good for cells to grow into) but still strong enough to act like real bone.
