1. A method of additive manufacturing for improving a shear strength of an object along a vertical axis, the improvement comprising:
(a) depositing at least three bead layers along a vertical axis of an object to be printed, the layers including (i) a bottommost layer comprising a plurality of adjacent bead layers deposited in the X-Y plane, each bead in the layer being oval in shape; (ii) at least one intermediate layer comprising a plurality of bead layers deposited in the X-Y plane; each bead in each of the plurality of intermediate bead layers being oval in shape, each bead of the intermediate bead layer being of uniform height; (iii) an uppermost layer comprising a plurality of adjacent bead layers deposited in the X-Y plane, each bead in the uppermost layer being oval in shape, and
(b) wherein by lowering the vertical axis of the bead height of a bead disposed between a bead on either side thereof in the uppermost and lowermost layers by reducing a flow rate of a material to be printed by one-half of the flow rate for manufacturing the bead height of the beads adjacent thereto to create an object, whereby the shear strength of the object is improved.
