A gaseous emissions treatment component is made by extruding a green ceramic mix through a die to form an extrusion having a honeycomb substrate with elongate cells extending its length and with the cells bounded by walls dividing adjacent cells from one another. Molten metal for use in induction heating of the component is placed in selected cells and is solidified by cooling.

The present invention is related to a porous ceramic composite structure with high mechanical strength and a wide range of porosity which makes flow rate of fluid highly tunable. The porous ceramic composite structure comprises a dense ceramic sheath and one or more inner porous ceramic bodies. The ceramic sheath provides good mechanical properties, protects the one or more inner porous ceramic bodies, and allows the one or more inner porous ceramic bodies to undergo a wide range of porosity changes while still maintaining excellent mechanical properties.

The compound nozzle for a cement 3D printer to produce thermally insulated composite cement is useful for producing composite thermally insulated cement sections using a 3D printer. The nozzle includes an insulation nozzle concentrically disposed in the central discharge orifice of the compound nozzle to produce a stream of insulation media axially surrounded by a stream of cement mixture extruded from the nozzle to form a wall with a cement exterior and an insulation interior. A motor-driven auger is controlled by a controller, and the cement is supplied from the top either manually or by a concrete pump. The insulating material is supplied to the insulation nozzle by a separate line that uses another pump. The system includes a cleaning mechanism to clean the internal components of the compound nozzle using water jets and a drying system to dry the internal components without disassembling the system.

The present invention includes an insulating panel for building structures, a printing device for making an insulating panel for building structures, and a method for the manufacturing of an insulating panel for building structures. The insulating panel resulting from the printing device comprises a multi-layered basalt sandwich wall that is made of external layers on either side of a middle layer. The external layers comprise a load-bearing coating made from basalt, and the middle layer comprises a heat insulating material made from basalt (basalt wool or foamed basalt). As a result, a specific sandwich-panel is manufactured from one local raw material (basalt), which possesses high mechanical and heat insulating properties. Such technology can be used for erecting comfortable buildings for colonists for long term use even under severe climatic conditions of solar system planets and satellites where appropriate raw materials exist.

A method of manufacturing a green body, the method comprising: providing: a third composition comprising a second substrate material, a third polymer, a fusing agent, and a third solvent; forming the third composition into a structure wherein the third composition forms a third layer; and contacting the third layer with a fourth solvent in which the third polymer is insoluble to precipitate said polymer, thereby forming a green body.

A substrate is further manufactured by: arranging a plurality of green bodies to form an assembly of green bodies;
fusing the green bodies in the assembly together, thereby forming a precursor substrate; and sintering the precursor substrate, thereby forming a substrate.

A radiation-shielding attenuation structure and method of forming the attenuation structure, wherein the attenuation structure is made by additively manufacturing a concrete material that includes one or more attenuation dopants configured to enhance the radiation shielding of the concrete material. The one or more attenuation dopants may be configured in the concrete material to attenuate one or more types of radiation, such as electromagnetic radiation, gamma radiation, X-ray radiation, or neutron radiation. The attenuation structure formed by the concrete material may be additively manufactured on-site according to a model that has already been pre-certified for safe or secure use, thereby providing a repeatable and reproducible process that can reduce lead times and fabrication costs. The attenuation structure may be easily modified during the additive manufacturing process to have different concrete mixtures with different attenuation characteristics, which increases the tailorability and flexibility in design of the attenuation structure.
