Abstract: A method for treating a powder, includes: dry mixing the powder with an effective amount of a treating additive to distribute a layer of the treating additive on a surface of a particle of the powder, a primary particle size of the treating additive being smaller than an average particle size of the powder. An associated treated powder is also described.

Abstract: A method of additively manufacturing an article includes forming a first portion of the article by three-dimensional printing of a plurality of first layers from a first powder material cut having a first average particle size corresponding to a first feature resolution. The first layers have a first average layer thickness. The method also includes forming a second portion of the article by three-dimensional printing of a plurality of second layers from a second powder material cut having a second average particle size corresponding to a second feature resolution less than the first feature resolution. The second portion includes at least one feature. The second layers have a second average layer thickness less than the first average layer thickness. A three-dimensional printing system and an article formed from a powder material by three-dimensional printing are also disclosed.
