1. A system for casing a wellbore of a hydrocarbon well, the system comprising:
a casing print head configured to be disposed in a wellbore of a hydrocarbon well, the casing liner print head comprising a row of nozzles, the row of nozzles comprising a first subset of nozzles configured to eject casing liner material, a second subset of nozzles configured to eject causing material, and a third subset of nozzles configured to eject disposable material; and
a well control system comprising a processor and non-transitory computer readable storage medium comprising program instructions stored thereon that are executable by the processor to cause the following:
conducting a downhole casing operation comprising:
operating the casing print head such that the casing print head rotates about a longitudinal axis of the wellbore and advances along the length of the wellbore, and the second subset of nozzles ejects casing material to form a casing tubular in the wellbore;
operating the casing print head such that the first subset of nozzles ejects cementitious casing liner material into an annular region located between the casing tubular and a wall of the wellbore to form a casing liner in the annular region formed of the cementitious casing liner material, such that the casing tubular and the casing liner are simultaneously deposited to form a casing of the wellbore;
forming a perforation in the casing, forming the perforation in the casing comprising operating the casing print head to form a contiguous void extending radially across the casing tubular and the casing liner, wherein operating the casing print head to form a contiguous void extending radially across the casing tubular and the casing liner comprises operating the casing print head such that the third subset of nozzles ejects a disposable material to define the contiguous void extending radially across the casing tubular and the casing liner; and
performing a perforation operation comprising removing the disposable material.
