Abstract
Method of manufacturing a wellbore downhole tool, including providing a pre-polymer resin and processing the pre-polymer resin. Processing the pre-polymer resin includes 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. A downhole tool for use in a wellbore, the downhole tool including a polymer seal. The polymer seal is a continuous single monolithic piece, includes polymer structures having a polymer chain including same types of monomers that are bonded together, and the polymer structures are altered along one or more dimensions of the polymer seal and one of more mechanical properties of the polymer seal differ along a same corresponding one of the or more dimensions of the polymer seal.
