Abstract
Official abstract text for this publication.
An additive manufactured multi-portion article includes a first portion of an article manufactured by a first additive manufacturing process; and a second portion of the article manufactured by a second additive manufacturing process different than the first additive manufacturing process, the second portion attached to the first portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of constructing an additive manufactured multi-portion article, comprising: additive manufacturing a first portion of the multi-portion article with a first additive manufacturing process; additive manufacturing a second portion of the multi-portion article with a second additive manufacturing process different than the first additive manufacturing process; and mechanically attaching the second portion to the first portion at an integral joining geometry, wherein the first additive manufacturing process is of a higher resolution than the second additive manufacturing process and the first additive manufacturing process operates at a different volumetric build rate than the second additive manufacturing process, the second portion forms a majority portion of the multi-portion article. 2. The method as recited in claim 1 , wherein the additive manufacturing of the first portion is faster than the additive manufacturing of the second portion. 3. The method as recited in claim 1 , wherein the additive manufacturing of the first portion is less accurate than the additive manufacturing of the second portion. 4. The method as recited in claim 1 , wherein attaching the second portion to the first portion comprises mechanical attaching. 5. The method as recited in claim 1 , wherein attaching the second portion to the first portion comprises mechanical attaching via a joint. 6. The method as recited in claim 1 , wherein the attaching the second portion to the first portion occurs during the additive manufacturing of the second portion. 7. The method as recited in claim 1 , further comprising computer modeling the multi-portion article and determining the second portion and the first portion with respect to the first additive manufacturing process and the second additive manufacturing process.
