Since the trained neural network can predict inherent strain quickly for any given hatch pattern , this could provide the basis for hatch pattern optimization of any part model to increase part build accuracy and achieve part GD & T callouts .
 concept or principle: neural network; machanical property: strain; concept or principle: pattern; concept or principle: pattern optimization; concept or principle: model; process parameter: build; process characterization: accuracy; material: GD
