Zusammenfassung:	Additive manufacturing processes for making transparent three-dimensional parts from inorganic material powders involve selective use of vacuum to remove or avoid trapped bubbles in the parts. La présente invention concerne des procédés de fabrication additive pour fabriquer des pièces en trois dimensions transparentes à partir de poudres de matériau inorganique, lesdits procédés comprenant l'utilisation sélective de vide pour éliminer les bulles captives dans les pièces ou éviter la formation de bulles captives dans les pièces.
