Abstract:
(EN) A method of forming a three-dimensional object, comprises providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; irradiating the build region through the optically transparent member to form a solid polymer from the polymerizable liquid while concurrently advancing the carrier away from the build surface to form the three-dimensional object from the solid polymer, while also concurrently: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface, and (ii) continuously maintaining a gradient of polymerization zone between the dead zone and the solid polymer and in contact with each thereof, the gradient of polymerization zone comprising the polymerizable liquid in partially cured form. Apparatus for carrying out the method is also described.
(FR) Procédé de formation d'un objet tridimensionnel consistant à utiliser un support et un élément optiquement transparent présentant une surface de construction, le support et la surface de construction délimitant une région de construction entre eux; remplir la région de construction avec un liquide polymérisable; exposer à des rayons la région de construction à travers l'élément optiquement transparent afin de former un polymère solide à partir du liquide polymérisable tout en éloignant simultanément le support de la surface de construction afin de former l'objet tridimensionnel à partir du polymère solide, tout en réalisant simultanément les étapes suivantes qui consistent à : (i) maintenir en continu une zone morte de liquide polymérisable en contact avec la surface de construction, et (ii) maintenir en continu un gradient de zone de polymérisation entre la zone morte et le polymère solide et en contact avec chacune d'elles, le gradient de zone de polymérisation comprenant un liquide polymérisable dans une forme partiellement durcie. L'invention se rapporte également à un appareil de réalisation du procédé.
