Abstract: A 3D printing apparatus including a manifold configured to receive a printing element; and a gasket disposed at a lower portion of the manifold. The manifold and gasket enclose the printing element, and the gasket defines a liquid-tight seal isolating the printing element from ambient. In another embodiment, a 3D printing apparatus includes a printing element; a manifold configured to receive the printing element; and a gasket disposed proximate the printing element, with the manifold and gasket together enclosing the printing element, and the gasket defining a liquid-tight seal that isolates the printing element from ambient. A service apparatus for washing a printing element, the apparatus including a parking element having at least one surface, and a frame defining a plurality of channels for introducing and draining a liquid solution when a printing element is parked against the surface of the parking element. Methods for capping, washing, preserving, and storing printing elements.

Abstract: A material system and method for bonding refractory powders in a three dimensional printer. A first particulate component including a refractory material is mixed with a first reactive component to form a particulate mixture. A flat layer of the particulate mixture is dispensed onto a build surface. A liquid binder, which may include a furan monomer and a surfactant, is dispensed by an ink-jet printhead onto the particulate mixture. The particulate mixture may contain a furan-soluble polymer that imposes a capillary attraction for the liquid binder, keeping it situated in the immediate vicinity of where the binder is dispensed. Additionally it provides a sufficient catalytic power to co-polymerize with the furan monomer and form a solid structure. This enables a 3D printer to build strong, accurate parts with high packing density, and to reuse the feed material many times in the printer.
