Title (EN) THREE-DIMENSIONAL PRINTING METHOD AND APPARATUS FOR REDUCING BUBBLES BY DE-GASSING THROUGH BUILD PLATE
(FR) PROCÉDÉ ET APPAREIL D'IMPRESSION EN TROIS DIMENSIONS PERMETTANT DE RÉDUIRE LES BULLES PAR DÉGAZAGE À TRAVERS UNE PLAQUE DE CONSTRUCTION
Abstract:
(EN) A method and an apparatus of forming a three-dimensional object includes providing a carrier and an optically transparent member having a build surface. The carrier and the build surface define a build region therebetween. The method further includes filling said build region with a polymerizable liquid; continuously or intermittently irradiating said build region with light through said optically transparent member to form a solid polymer from said polymerizable liquid; applying a reduced pressure and/or polymer inhibitor-enriched gas to the polymerizable liquid through the optically transparent member to thereby reduce a gas content of the polymerizable liquid; and continuously or intermittently advancing (e.g., sequentially or concurrently with said irradiating step) said carrier away from said build surface to form said three-dimensional object from said solid polymer.
(FR) L'invention concerne un procédé et un appareil de formation d'un objet en trois dimensions, qui comprennent l'utilisation d'un support et d'un élément optiquement transparent ayant une surface de construction. Le support et la surface de construction délimitent une région de construction située entre eux. Le procédé consiste en outre à remplir la région de construction de liquide polymérisable ; à exposer en continu ou par intermittence la région de construction à de la lumière à travers l'élément optiquement transparent pour former un polymère solide à partir du liquide polymérisable ; à appliquer une pression réduite et/ou un gaz enrichi en inhibiteur de polymère sur le liquide polymérisable à travers l'élément optiquement transparent afin de réduire ainsi la teneur en gaz du liquide polymérisable ; et à faire avancer le support en continu ou par intermittence (par exemple séquentiellement ou en même temps que l'étape d'exposition) pour l'éloigner de la surface de construction et former l'objet en trois dimensions à partir du polymère solide.
