Abstract
An article of manufacture includes a part structure formed via a first additive manufacturing process and a floating structure within the part structure which is mechanically decoupled from the part structure. The floating structure is formed concurrently with the part structure via the first additive manufacturing process.
Claims10
An article of manufacture comprising:
- a part structure, the part structure formed via a first additive manufacturing process, the part structure defining at least one channel and a depth-wise direction along a length of the at least one channel;
- and
- a plurality of floating structures disposed within the part structure, the plurality of floating structures mechanically decoupled from the part structure, a first floating structure and a second floating structure disposed within the at least one channel and arranged with a depth spacing between adjacent ends of the first and second floating structures along the depth-wise direction, the depth spacing defining how far second floating structure is behind the first floating structure,
- wherein the plurality of floating structures are formed concurrently with the part structure, and wherein the plurality of floating structures occupy from 80% to 99% of the volume of the at least one channel;
- and
- wherein the at least one channel defined by the part structure respectively comprise an opening sized for removal of the plurality of floating structures.

An article of manufacture comprising:
- a part structure, the part structure formed via a first additive manufacturing process, the part structure defining a channel;
- powder disposed within the part structure;
- and
- at least one floating structure disposed within the channel of the part structure, the at least one floating structure mechanically decoupled from the part structure, the at least one floating structure defining the same or similar cross-sectional shape as defined by the channel, and wherein the at least one floating structure defines the same or similar aspect ratio as defined by the channel in a plane perpendicular to the same or similar cross-sectional shape,
- wherein the powder encapsulates the at least one floating structure, and wherein the at least one floating structure occupies from 80% to 99% of the volume of the channel;
- and
- wherein the channel defined by the part structure comprises an opening sized for removal of the at least one floating structure.
