1. A method comprising:
receiving data associated with a part to be built by additive manufacturing using a recoater;
predicting a distortion amount comprising a distance that the part is expected to distort in a vertical direction at one or more layers while the part is being built based on a simulation of the part being built;
determining a likelihood of a recoater event based on the predicted distortion amount;
determining a severity factor associated with the predicted distortion amount at each of the one or more layers of the part based on an orientation of the part at each of the one or more layers; and
determining an adjusted likelihood of a recoater event at each of the one or more layers of the part based on the predicted distortion amount and the determined severity factor.
