Title (EN) METHOD OF FORMING POROUS THREE-DIMENSIONAL (3D) ARTICLE
(FR) PROCÉDÉ DE FORMATION D'UN ARTICLE TRIDIMENSIONNEL (3D) POREUX
Abstract:
(EN) A method of forming a porous three-dimensional (3D) is disclosed. The method comprises (I) printing a first composition on a substrate (16) with the nozzle (12) of the apparatus (10) to form at least one first filament (14) comprising the first composition, (II) selectively controlling the distance and/or the speed such that the at least one first filament coils on the substrate to give a first layer on the substrate, the first layer comprising a coiled filament, optionally repeating steps I) and II) with independently selected composition(s) for any additional layer(s), and (III) exposing the layer(s) to a solidification condition. A porous three-dimensional (3D) article formed in accordance with the method is also disclosed.
(FR) La présente invention concerne un procédé de formation d’un article tridimensionnel (3D). Le procédé comprend (I) l'impression d'une première composition sur un substrat (16) avec la buse (12) de l'appareil (10) pour former au moins un premier filament (14) comprenant la première composition, (II) la commande sélective de la distance et/ou de la vitesse de telle sorte que l'au moins un premier filament s'enroule sur le substrat pour donner une première couche sur le substrat, la première couche comprenant un filament enroulé, éventuellement la répétition des étapes I) et II) avec une ou plusieurs compositions sélectionnées indépendamment pour une ou plusieurs couches supplémentaires, et (III) l'exposition de la ou des couches à une condition de solidification. La présente invention concerne également un article tridimensionnel (3D) poreux formé selon le procédé.
