Patent ID: 7575708

Claim:
A process of fabricating a production grade aerospace part, the process comprising the operations of: loading a powder nylon material into a laser sintering machine; warming the powder nylon material according to build warm-up parameters, the build warm-up parameters comprising a stage height, feed distances, heater set points, a minimum layer time, and a part heater inner/outer ratio; and building the production grade aerospace part according to build parameters, the build parameters comprising: left and right feed heater set points; a part heater set point during a warm-up phase of between T glaze −2° C. to T glaze −4° C., and during a build phase of T glaze −2° C. to T glaze −6° C.; a fill scan spacing; a fill laser power of between about 15-20 watts; and a fill scan speed; wherein said production grade aerospace part comprises an ultimate tensile strength of at least approximately 4000 pounds per square inch at approximately 70 degrees Fahrenheit.
