Title (EN) TECHNIQUES FOR FLUID CONTROL IN ADDITIVE FABRICATION AND RELATED SYSTEMS AND METHODS
(FR) TECHNIQUES DE COMMANDE DE FLUIDE EN FABRICATION ADDITIVE ET SYSTÈMES ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) According to some aspects, a method is provided of forming an object via additive fabrication, the method comprising forming a first layer of the object by depositing a plurality of droplets of a first liquid and curing the first liquid to form solid material, the first layer including a region of a first solid material, and a region of a second solid material in contact with the region of the first solid material, and depositing a second liquid onto the region of the first solid material and at least part of the region of the second solid material, wherein the second liquid, once deposited, uniformly spreads over the region of the first solid material whilst exhibiting partial wetting over the at least part of the region of the second solid material.
(FR) Selon certains aspects, l'invention concerne un procédé de formation d'un objet par fabrication additive, le procédé comprenant la formation d'une première couche de l'objet par le dépôt d'une pluralité de gouttelettes d'un premier liquide et le durcissement du premier liquide afin de former un matériau solide, la première couche comprenant une région d'un premier matériau solide, et une région d'un second matériau solide en contact avec la région du premier matériau solide, et le dépôt d'un second liquide sur la région du premier matériau solide et d'au moins une partie de la région du second matériau solide, le second liquide, une fois déposé, s'étalant uniformément sur la région du premier matériau solide tout en présentant une humidification partielle sur l'au moins une partie de la région du second matériau solide.
