1. A method of manufacturing a wellbore downhole tool, comprising:
providing a pre-polymer resin; and
processing the pre-polymer resin including applying directed energy from a directed energy source such that the pre-polymer resin is at least partially polymerized to form a polymer seal of the wellbore downhole tool, the polymer seal having one of more mechanical properties that differ along one or more dimensions of the polymer seal.
