Abstract

An additive manufacturing machine (100) forms a part (130) utilizing additive manufacturing and with a plurality of layers. A controller (140) includes processing circuitry and a memory (144), and is operable for receiving design information about a proposed part (130) to be manufactured utilizing additive manufacturing, and also receives proposed process parameters for the additive manufacturing machine (100). The controller (140) is operable to predict a temperature at each of a plurality of layers that will be found in the proposed part (130), and identify a temperature history for a plurality of the layers including identifying the time to solidify for at least one of the plurality of layers, and determine a derivative of a change in temperature of the at least one of the plurality of layers over time and predicting grain structure utilizing the derivative. The controller (140) is operable to determine an expected life based upon the predicted grain structure. A method is also disclosed.
