Abstract
The biocompatible lattice structures disclosed herein with an increased or optimized lucency are prepared according to multiple methods of design disclosed herein. The methods allow for the design of a metallic material with sufficient strength for use in an implant and that remains radiolucent for x-ray imaging.
Claims15
A method for manufacturing a biocompatible porous structure having increased lucency along at least one X-ray viewing direction, the method comprising:
- using an analysis tool, generating a bulk volume comprising a plurality of repeating geometric unit cells, the repeating geometric unit cells comprising a plurality of nodes and a plurality of struts configured such that each strut extends radially from at least one node within a volume of the biocompatible porous structure, wherein the analysis tool is configured to analyze multiple variables;
- propagating the bulk volume throughout the biocompatible porous structure;
- calculating a bulk volume thickness for the biocompatible porous structure along the at least one X-ray viewing direction;
- using the analysis tool, iterating across a plurality of rotations of the biocompatible porous structure to identify one or more variables resulting in the bulk volume thickness that provides the biocompatible porous structure with a predetermined lucency along the at least one X-ray viewing direction;
- and
- manufacturing the biocompatible porous structure using the one or more variables.
