1. A method for manufacturing a deflection member, the method comprising the steps of:
a.) providing an additive manufacturing apparatus that comprises at least one upper radiation source, at least one lower radiation source, and photopolymer resin;
b.) providing a reinforcing member having an upper surface and a lower surface opposite the upper surface;
c.) submerging the reinforcing member into the photopolymer resin such that at least one of the lower and upper surfaces of the reinforcing member faces at least one of the lower and upper radiation sources; and
d.) directing radiation from the at least one of the lower and upper radiation sources toward at least one of the lower and upper surfaces of the reinforcing member to the cure at least a portion of the photopolymer resin to form at least a portion of a lock-on layer.
