Abstract
Methods and systems for predicting deformation error and compensating for shape deviation in Additive Manufacturing (AM) techniques include, in one aspect, a method including: obtaining a deformation model for an AM machine; predicting deformation for the object using the deformation model applied to the 3D model; selecting an amount of deformation compensation to effect by minimizing deviation for the predicted deformation; and providing the selected amount of deformation compensation to modify the 3D model to compensate for deformation during creation by the AM machine.
