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.
