Abstract
An exemplary method for determining a set of additive manufacturing parameters includes, a) determining a nominal parameter of at least one surface of a component, b) determining at least a second order variation in the nominal parameter, c) predicting an actual resultant dimension based at least in part on the nominal parameter and the second order variation, and d) adjusting at least one additive manufacturing process parameter in response to the predicted actual resultant dimension.

A method for determining a set of additive manufacturing parameters comprising:
- a) determining a nominal parameter of at least one surface of a component;
- b) determining at least a second order variation in said nominal parameter, wherein the at least a second order variation includes at least one of powder perturbations, powder particle size variations, power source variations, beam profile, and orientation of a sintered surface relative to prior and subsequent sintered surfaces;
- c) predicting an actual resultant dimension based at least in part on the nominal parameter and the second order variation;
- and
- d) adjusting at least one additive manufacturing process parameter in response to said predicted actual resultant dimension.
A method for determining a set of additive manufacturing parameters comprising:
