Abstract
An additively manufactured component that includes a tool with a region having a plurality of overlying metal layers each derived from a metal powder filament. The region has a predetermined yield point selected based on an operation to be performed with the tool.
Claims7
A method for additively manufacturing a component, the method comprising:
- forming the component on the major surface of a substrate, wherein the component comprises a region comprising a plurality of overlying metal layers, wherein the metal layers are each derived from a filament comprising a powder comprising a polymeric binder and a metal, and wherein the region has a predetermined yield point selected based on a selected composition function of the component;
- forming a first portion of the region, wherein the first portion comprises a first thickness, wherein the first portion further comprises a first cross-sectional shape, and wherein the first portion further comprises a first yield point;
- and
- forming a second portion of the region, wherein the second portion comprises a second thickness that is different from the first thickness, wherein the second portion further comprises a second cross-sectional shape that is different from the first cross-sectional shape, wherein the second portion further comprises a second yield point that is different from the first yield point, and wherein the second portion fails at a predetermined stress level.
