Abstract
Methods, architectures, mechanisms and/or apparatus configured to manufacture a component (and components manufactured thereby) by optimizing a location of an internal feature of the component to be manufactured using powder fusion additive manufacturing (PFAM) based on an energy release rate being proportional to the third derivative of a component shape function and the shape function itself; the internal feature comprising one or more cavities having unfused powder disposed therein to provide vibration dampening.
Claims8
A method of manufacturing a component an internal feature therein, the method comprising:
- developing a component design of the component;
- using the component design,
- optimizing a location of the internal feature of the component to be manufactured using powder fusion additive manufacturing (PFAM) based on an energy release rate being proportional to the third derivative of a component shape function and the shape function itself;
- and
- manufacturing the component using the optimized component design and a powder fusion additive manufacturing (PFAM) process based on an energy release rate being proportional to the third derivative of a component shape function and the shape function itself,
- wherein the internal feature comprises one or more cavities having unfused powder disposed therein to provide vibration dampening.
