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.
Claims20
An article of manufacture comprising:
- a part structure, the part structure formed via a first additive manufacturing process;
- and
- at least one floating structure disposed within the part structure, the at least one floating structure mechanically decoupled from the part structure,
- wherein the at least one floating structure is formed concurrently with the part structure via the first additive manufacturing process.
1 more element
A powder removal method comprising:
- identifying a part geometry;
- identifying at least one cavity within the part to place at least one powder removal feature;
- defining at least one characteristic of the at least one powder removal feature;
- creating a build file for forming the part and the at least one powder removal feature via a generative build process;
- generatively forming the part and the at least one powder removal feature;
- and
- vibrating the part and the at least one powder removal feature.
4 more elements
The method of claim 19, further comprising generatively forming more than one powder removal feature,
- wherein defining at least one characteristic of the at least one powder removal feature comprises at least one of defining a powder removal feature shape, dimension, orientation within the part, location within the part, and porosity.
An article of manufacture comprising:
- a part structure, the part structure formed via a first additive manufacturing process;
- powder disposed within the part structure;
- and
- at least one floating structure disposed within the part structure, the at least one floating structure mechanically decoupled from the part structure,
- wherein the powder encapsulates the at least one floating structure.
