Beschreibung
Zusammenfassung:	In one aspect, additive manufacture techniques are described herein which enable the densification of green articles prior to further article processing. In some embodiments, a method of forming an article comprises providing a powder composition, and forming the powder composition into a green article by one or more additive manufacturing techniques. The green article is contacted with a powder pressure transfer media. The green article and powder pressure transfer media are then subjected to cold isostatic pressing (CIP) or warm isostatic pressing (WIP) at a pressure less than minimum isostatic compaction pressure of the powder pressure transfer media to provide a densified green article.
