## Abstract

Provided are systems and methods for forming a casing liner in a wellbore of a hydrocarbon well. The forming including disposing a casing liner print head in an annular region located between a casing pipe disposed in a wellbore of a hydrocarbon well and a wall of the wellbore, conducting a downhole lining operation including operating the casing liner print head to eject casing liner integrated structure material into the annular region to form, in the annular region, a casing liner integrated structure including contiguous voids formed in the casing liner integrated structure material, and depositing a cementitious material into the contiguous voids formed in the casing liner material to form, in the annular region, a casing liner including the casing liner integrated structure material and the cementitious material.
