Title:
MANUFACTURING AIRCRAFT PARTS
Document Type and Number:
WIPO Patent Application WO/2010/080659
Kind Code:
A3
Abstract:
A method and apparatus is present for manufacturing parts (1200). A powder material is comprised of a polymer that is semi-crystalline. The powder material has an overlap (506) between a melting temperature range and a crystallization temperature range. The powder material also has a size particular distribution that is substantially a Gaussian distribution, a particle shape that is substantially spherical, and a desired melt flow rate that is less than a temperature at which the powder material begins to chemically break down. The powder material is selected to form a selected powder material. A part (1200) is manufactured using an energy delivery system and the selected powder material.
