Provided are a structure and a method of forming a structure that includes a core made, at least in part, of a rice hull composition. The rice hull composition including a combination of separate, unground rice hulls; ground rice hulls; and a rice hull powder, that each have a different particle size. A polymeric binder, such as a recycled plastic polymeric binder binds the separated unground rice hulls, the ground rice hulls and the rice hull powder together.

A system and a method of manufacturing continuous glass filament fiberglass media comprises melting glass within a temperature controlled melter. Molten glass exits through orifices in a bushing plate. The resulting fiberglass filaments are received on a rotating drum and sprayed with binder and aqueous solution. The resulting fiberglass mat is placed onto a let-off table then sprayed with aqueous solution before further processing.

A three-dimensional object that is bigger than an irradiation area of a light beam by one irradiation device is simply, easily and precisely shaped.

A three-dimensional object shaping device (1) shapes a three-dimensional object that is a laminated body of hardened layers made of a shaping material, in a horizontal, shaping area (7) which holds the shaping material hardened by irradiation, of a light beam (L). An irradiation device (30) irradiates the light beam (L) to an irradiation area (8) in the shaping area (7) from above the shaping area (7). A shaping table (10) has the shaping area (7) that is larger than the irradiation area (8). A moving device moves the shaping table (10) in a horizontal direction so as to change a position of the irradiation area (8) in the shaping area (7).

A three-dimensional (3D) printing composite build material composition includes a polymer particle and an inorganic particle. The polymer particle is an aliphatic polyamide. The inorganic particle has an average particle size ranging from about 1 m to about 100 m. A mass ratio of the polymer particle to the inorganic particle in the composite build material composition ranges from about 5:2 to about 1:3.

A system and method of forming fiberglass air filtration media is disclosed which does not require the use of oil additives. A mixture of resin binder, polymer, and dry adhering agent is formed and applied to the fiberglass as it spins onto the drum. Additionally, the fiberglass filtration media density can vary such that the fiber on the air inflow is less dense than the fiber on the air outflow. After oven curing, the finished air filtration media has an improved ability to attract and hold dust and other contaminants.

An oven for baking a thermally curable binder in a mat of mineral fibers, including plural compartments through which the mat of fibers passes successively, the mat being compressed and transported through the compartments by gas-permeable upper conveyors and lower conveyors, each compartment having a length along a direction of movement of the mat and including a mechanism introducing a hot air flow, located either below or above the fiber mat, and a mechanism extracting the air after having passed through the mat, respectively arranged either above or below the opposite face of the mat, so that the binder is progressively brought to a temperature higher than its curing temperature. In one compartment the mechanism introducing hot air includes air inlets that open partly on openings formed on a first lateral side of the compartment and partly on openings formed on the opposite lateral side of the compartment.
