Title:
ポリマー粉末およびその調製方法
Document Type and Number:
Japanese Patent JP7382408
Kind Code:
B2
Abstract:
A powder composition suitable for use in selective laser sintering for printing an object. The powder composition includes a first fraction including a plurality of polyaryletherketone (PAEK) particles having a mean diameter less than 30 microns, a second fraction having a plurality of polyaryletherketone (PAEK) particles having a mean diameter greater than 30 microns, and a third fraction having a plurality of carbon fibers. The first fraction and the second fraction are formed by an air classification separation performed on a pulverized powder. After the separation, the first fraction, the second fraction, and the third fraction are blended in a high intensity mixer. The powder composition when used in selective laser sinter results in parts with increased tensile strength and reduced surface roughness, among other improvements, as compared to similar powders omitting the first fraction. The PAEK may include polyetherketoneketone (PEKK).
