ADDITIVE MANUFACTURING SYSTEM, ARTICLE, AND METHOD OF MANUFACTURING AN ARTICLE

A method of additively manufacturing an article (100) includes forming a first portion (210) of the article (100) by three-dimensional printing of a plurality of first layers from a first powder material cut (301) having a first average particle size corresponding to a first feature resolution. The...

Zusammenfassung:	A method of additively manufacturing an article (100) includes forming a first portion (210) of the article (100) by three-dimensional printing of a plurality of first layers from a first powder material cut (301) 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 (220) of the article (100) by three-dimensional printing of a plurality of second layers from a second powder material cut (302) having a second average particle size corresponding to a second feature resolution less than the first feature resolution. The second portion (220) includes at least one feature (230). The second layers have a second average layer thickness less than the first average layer thickness. A three-dimensional printing system (400) and an article (100) formed from a powder material by three-dimensional printing are also disclosed.
