Component and Watermark Formed by Additive Manufacturing

摘要

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.

1. A method of forming a three-dimensional article comprising:
sequentially forming a plurality of first two-dimensional layers, each first two-dimensional layer including a first outer edge defining a first boundary of the first two-dimensional layer and a first inner area within the first boundary defined by the first outer edge; forming a second two-dimensional layer adjacent one of the plurality of first two-dimensional layers, the second two-dimensional layer including a second outer edge defining a second boundary of the second two-dimensional layer and a second inner area within the second boundary defined by the second outer edge, the second outer edge being aligned with the first outer edge of the adjacent one of the plurality of first two-dimensional layers, the second inner area having a physical characteristic and a watermark area within the second inner area having a physical characteristic different from the physical characteristic of the second inner area.
