Manufacturing aircraft parts |
摘要 |
A method and apparatus is present for manufacturing parts. A powder material is comprised of a polymer that is semi-crystalline. The powder material has an overlap 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 is manufactured using an energy delivery system and the selected powder material. |
