Abstract
A component incorporating a 3-D identification code includes: a component body having an interior bounded by an exterior surface; and an identification code formed as a part of at least one of the interior and the exterior surface, the identification code including a plurality of cells arranged in a three-dimensional space, wherein each of the cells is configured to encode more than two possible values.

A component incorporating a 3-D identification code, comprising:
- a component body having an interior bounded by an exterior surface;
- and
- an identification code formed as a part of at least one of the interior or the exterior surface, the identification code including a plurality of cells arranged in a three-dimensional space, wherein each of the cells is configured to encode more than two possible values, and wherein at least two cells are displaced from each other in each of three dimensions.
A method of making a component incorporating a 3-D identification code, comprising:
- depositing a powder onto a worksurface;
- using radiant energy to fuse the powder;
- and
- repeating the steps of depositing and fusing the powder to build up the component in a layer-by-layer fashion, the component including a component body having an interior bounded by an exterior surface;
- and an identification code formed as a part of the interior, the identification code including a plurality of cells arranged in a three-dimensional space within the interior, wherein the cells are defined by varying position-independent properties.
