Three-dimensional porous structures for bone ingrowth and methods for producing

A method of manufacturing an orthopaedic prosthetic component comprising:

• creating a porous three-dimensional structure by causing a computing device to perform the steps of:
• defining a three-dimensional space having an inner boundary and an outer boundary;
• randomly positioning a plurality of seed points within the three-dimensional space;
• defining a plurality of cells by a Voronoi structure such that each cell includes one of the seed points, the plurality of cells separated from each other by struts that intersect at a plurality of nodes;
• modifying at least one of the nodes or the struts such that the porous three-dimensional structure comprises a lattice structure other than a Voronoi structure;
• and
• after the modifying step, generating instructions to fabricate the porous three-dimensional structure, such that the orthopaedic prosthetic component is organicized.
