摘要:
Porous biocompatible structures suitable for use as medical implants and methods for fabricating such structures are disclosed. The disclosed structures may be fabricated using rapid manufacturing techniques. The disclosed porous structures each have a plurality of struts and nodes where no more than two struts intersect one another to form a node. Further, the nodes can be straight, curved, and can include portions that are curved and/or straight. The struts and nodes can form cells that can be fused or sintered to at least one other cell to form a continuous reticulated structure for improved strength while providing the porosity needed for tissue and cell in-growth.
