Abstract: A process of fabricating aerospace parts using selective laser sintering is provided, wherein the process generally comprises the steps of preparing a powder nylon material, loading the powder nylon material into a laser sintering machine, warming up the powder nylon material according to build warm-up parameters, building the part according to build parameters and part parameters, and cooling down the part according to build cool-down parameters. As a result, parts are produced that are directly used in aerospace structures, which meet the stringent performance requirements of aerospace applications, rather than as rapid prototypes as with conventional selective laser sintering processes. Additionally, specific designs for aerospace parts such as ducts, panels, and shrouds are provided that are produced by the selective laser sintering process.

Abstract: A self-contained parts kit is created by forming a container around parts formed using a direct manufacturing process. The formation of the container is part of the same process by which the parts are formed. The container can be formed with one or more openings by which the parts can be removed. The container can also be formed with perforations in one or more surfaces to allow the parts therein to be cleaned without removing the parts, such as by shaking or by the external application of a fluid such as pressurized air. Indicia can also be formed on the container.

Abstract: Honeycomb products and methods of manufacture thereof, particularly for aerospace applications. The honeycomb core products are made of a plastic material, such as a thermoplastic material, and preferably are made by a direct manufacturing process, such as stereo lithography, selective laser sintering, or fused deposition modeling. The cell sizes, shapes and wall thicknesses can be modified or varied throughout the product as desired. An interlocking structure is utilized to securely hold together adjacent honeycomb products.
