Abstract:
A method of laser sintering a thermoplastic composition to provide an article of manufacture having a plurality of sintered layers is disclosed. The thermoplastic composition has a relatively high melting point and a small particle size. The articles of manufacture have a high resolution and excellent durability and strength.
Abstract:
Powder compositions and articles and methods of forming articles from powder compositions are provided. The powder compositions include at least one polymer powder and an amount of reinforcing particles having an aspect ratio of preferably at least about 5:1. In a preferred embodiment, the powder composition is capable of being formed, via a laser sintering process, into a three-dimensional article that exhibits one or more desirable mechanical properties in an elevated temperature environment.
Abstract:
Una composición de revestimiento que comprende una mezcla de una o más resinas de poliéster que tienen un peso molecular promedio inferior e índice de fluidez superior, donde la composición de revestimiento se encuentra en la forma de un polvo que tiene partículas con una distribución de partícula fina, y en donde la composición de revestimiento se configura para formar un revestimiento delgado (34) prácticamente libre de poros.

Abstract:
A coating composition comprising a blend of one or more polyester resins and a low molecular weight highly functional resin component is described herein, where the coating composition is in the form of a powder and is configured to form a thin coating that demonstrates optimal adhesion to the substrate.
Abstract:
A coating composition comprising a blend of one or more polyester resins having a lower average molecular weight and higher melt flow index, where the coating composition is in the form of a powder having particles with a fine particle size distribution, and where the coating composition is configured to form a thin coating (34) that is substantially free of pores.
Abstract:
Powder compositions and articles and methods of forming articles from powder compositions are provided. The powder compositions include at least one powder that preferably includes an amount of one or more branched polymers such as, for example, one or more branched polyamide polymers. The powder composition is preferably capable of being formed, via a layer-by-layer sintering process such as, for example, selective laser sintering, into a three-dimensional article.
