Abstract
Official abstract text for this publication.
A method of forming a three-dimensional article includes sequentially forming a plurality of first two-dimensional layers and a second two-dimensional layer. The second two-dimensional layer includes a second outer edge and a second inner area within the boundary defined by the second outer edge. The second inner area includes uniform physical characteristic and a watermark area within the second inner area having a physical characteristic different from that of the second inner area. An article includes a body with an inner area having a physical characteristic. A watermark is within the inner area and has a physical characteristic different from the physical characteristic of the inner area.
First claim
Opening claim text (preview).
The invention claimed is: 1. An article comprising: a body having an outer surface surrounding an inner area, the inner area having a physical characteristic; a watermark embedded within and surrounded by the inner area, the watermark having a physical characteristic different from the physical characteristic of the inner area; and an indicator exposed on the outer surface of the body, the indicator indicating a location of the embedded watermark in the body. 2. The article of claim 1 , wherein the body and watermark are formed of a single material. 3. The article of claim 1 , wherein the watermark has a different density than the inner area. 4. The article of claim 1 , wherein the watermark has a different crystallinity than the inner area. 5. The article of claim 1 , wherein the indicator is a code on the outer surface indicative of a location of the watermark. 6. The article of claim 5 , where the code is indicative of a distance of the watermark from the outer surface. 7. The article of claim 6 , wherein the code is further indicative of an angle of the watermark from a reference point. 8. The article of claim 1 , wherein the watermark is positioned beneath the indicator.
