Assignee:

The Boeing Company - Chicago IL

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.:

10/458636

Inventors:

Jeffrey Fink - , US
Tracy Taylor - Simi Valley CA, US
Lori Wegner - Santa Monica CA, US
Bryon Shapey - Thousand Oaks CA, US

International Classification:

B29C035/04

US Classification:

700/098000, 264/497000

Abstract:

A method for improving production parts produced from a rapid prototyping machine that includes the step of generating a build run that produces output components having production parts and/or iterative improvement specimens. A comparison of the production parts and/or iterative improvement specimens is made to a set of input data that includes dimensions and material characteristics. The comparison produces a resultant data set that includes deviations between the input data and the output components. Build parameters are then tailored for the rapid prototyping machine to reduce deviations between the input data and the output components as compared to previous build runs.

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.
