Title (EN) MULTI-MATERIAL SEPARATION LAYERS FOR ADDITIVE FABRICATION
(FR) COUCHES DE SÉPARATION MULTI-MATÉRIAU POUR FABRICATION ADDITIVE
Abstract:
(EN) According to some aspects, a container is provided for use in an additive fabrication device configured to fabricate parts by curing a liquid photopolymer to form layers of cured photopolymer. The container may comprise a laminated multi-material layer having an elastic first layer that aids in separation of cured photopolymer from the container in addition to a barrier layer on an upper surface that protects the first layer from exposure to substances in the liquid photopolymer that may not be compatible with the material of the first layer.
(FR) L'invention concerne, selon certains aspects, un récipient destiné à être utilisé dans un dispositif de fabrication additive configuré pour fabriquer des pièces en durcissant un photopolymère liquide pour former des couches de photopolymère durci. Le récipient peut comporter une couche multi-matériau stratifiée comprenant une première couche élastique qui aide à séparer le photopolymère durci du récipient en plus d'une couche de barrière sur une surface supérieure qui protège la première couche de l'exposition à des substances présentes dans le photopolymère liquide qui pourraient ne pas être compatibles avec le matériau de la première couche.
