METHODS AND SYSTEMS FOR PRINTING 3D OBJECT BY INKJET

3D (three-dimensional) ink-jet printing includes techniques for evaporating a carrier liquid during printing while at least a portion of dispersant remains in the printed layer; evaporating dispersant in a first layer prior to sintering the first layer and/or prior to printing a second layer; leveli...

Zusammenfassung:	3D (three-dimensional) ink-jet printing includes techniques for evaporating a carrier liquid during printing while at least a portion of dispersant remains in the printed layer; evaporating dispersant in a first layer prior to sintering the first layer and/or prior to printing a second layer; leveling an upper-layer of a printed object using a horizontal roller; and printing layers of an object, each layer with both object and support portions, resulting in an object with support, in particular, support for negative angles and molds. L'invention concerne une impression par jet d'encre 3D (tridimensionnelle), qui comprend des techniques pour faire s'évaporer un liquide porteur pendant une impression, tandis qu'au moins une partie d'un agent dispersant reste dans la couche imprimée; faire s'évaporer l'agent dispersant dans une première couche avant le frittage de la première couche et/ou avant l'impression d'une seconde couche; mettre à niveau une couche supérieure d'un objet imprimé à l'aide d'un rouleau horizontal; et imprimer des couches d'un objet, chaque couche ayant des parties objet et support, conduisant à un objet ayant un support, en particulier un support pour des angles négatifs et des moules.
