International Classification:

B29C 35/08
B29C 41/02
G06F 19/00

US Classification:

264497, 264 401, 700119, 700212

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.

Appl. No.:

10/608272

Inventors:

Jeffrey Fink - West Hills CA, US
Tracy Taylor - Semi Valley CA, US
Lori Wegner - Santa Monica CA, US
Mark Wilenski - Seattle WA, US

International Classification:

B05D003/06
C23F001/00

US Classification:

216/066000, 427/551000, 427/558000

Abstract:

Methods and systems for changing properties of a layer-formed plastic part comprised of at least one plastic material are disclosed. In one embodiment, an electromagnetic radiation source is provided and the layer-formed plastic part is positioned within a potential exposure range of the electromagnetic radiation source. An exposure of radiation from the electromagnetic radiation source operable to change the property of the layer-formed plastic part from the existing state to an altered state is determined. The layer-formed plastic part is then exposed to the radiation to change the property of the layer-formed plastic part to the altered state.

US Classification:

700212, 4251744

Abstract:

A process of for creating process build parameters includes creating a set of process build parameters for laser-sintering of a part based on a thermal model of a parts bed of a laser sintering machine and empirical data from prior laser-sintered parts built in the parts bed.
