Provided are systems and method for casing a wellbore of a hydrocarbon well. The casing including disposing a casing print head in a wellbore of a hydrocarbon well, and conducting a downhole casing operation including operating the casing print head to eject casing material to form a casing tubular in the wellbore, and operating the casing print head to eject 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, the casing tubular and the casing liner forming a casing of the wellbore.

This disclosure provides interlocking blocks molds that can be connected on any side to form an interlocking block mold, interlocking block, structure, wall, foundation, floor, building, flotation device, gardening structure, artificial coral reefs, or toy. The interlocking blocks molds typically comprise center outward protrusions and connecting outward protrusions on each side and can be connected with hardware through the connecting outward protrusions or with a connection coupling on the exterior of the outward protrusions. The center outward protrusions allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked block molds. Connected block molds can also be filled with fortifying material to strengthen the structure. Sides of connected block molds exterior protrusions can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connection couplings for connecting sides of the interlocking blocks molds.

Provided is a wellbore casing liner printing system that includes a casing liner print head adapted to be disposed in an annular region located between a casing pipe disposed in a wellbore of a hydrocarbon well and a wall of the wellbore and adapted to rotate within the annular region and deposit material into the annular region to form a casing liner in the annular region. The casing liner print head including a first set of printing nozzles arranged in series in a radial direction, and a second set of printing nozzles arranged in series in the radial direction and offset from the first set of printing nozzles. The first set of printing nozzles adapted to eject a first casing liner material into the annular region and the second set of printing nozzles adapted to eject a second casing liner material into the annular region to form the casing liner of the first casing liner material and the second casing liner material.

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, and conducting a downhole lining operation including operating the casing liner print head to eject casing liner material into the annular region to form, in the annular region, a casing liner including elongated voids formed in the casing liner material.

A method for infiltrating a porous preform for a gas turbine engine is provided, which comprises providing a chamber for infiltrating a porous preform. The porous preform is positioned within a slurry confinement fixture within the chamber. A vacuum is created in the chamber. A solvent is added to the slurry confinement fixture until a pressure in the chamber is substantially equal to an equilibrium partial pressure of the solvent. A slurry is added to the slurry confinement fixture. The slurry includes the solvent and a particulate. The pressure in the chamber is increased, and the slurry is urged into the porous preform.
