Neural network architecture for predicting bead geometry. Illustrations of different deposition paths. External lines represent the boundary of the geometry; internal lines represent the deposition paths with the numbers representing the order of the deposition paths; grey regions are deposited area by the relevant paths. (a) Contour path patterns; (b) the predicted high accuracy deposition but with internal gaps; (c) MAT path patterns; (d) the predicted void-free deposition but with extra material deposited along the boundary; (e) adaptive MAT path patterns with varying step-over distance; (f) the predicted void-free deposition with high accuracy at the boundary through using adaptive MAT path.
