Title (EN) HYDROGEL COMPOSITE INK FORMULATION AND METHOD OF 4D PRINTING A HYDROGEL COMPOSITE STRUCTURE
(FR) FORMULATION D'ENCRE COMPOSITE AVEC HYDROGEL ET PROCÉDÉ D'IMPRESSION 4D D'UNE STRUCTURE COMPOSITE AVEC HYDROGEL
Abstract:
(EN) A method of 4D printing comprises depositing a layer of filaments in a predetermined arrangement on a flexible substrate. Each filament comprises a hydrogel matrix and a plurality of anisotropic filler particles embedded therein. The filaments contact the flexible substrate at one or more contact regions. The layer of filaments is hydrated, and the filaments swell in size while remaining in contact with the flexible substrate at the contact regions. The flexible substrate is thereby induced to adopt a predetermined curved shape.
(FR) L'invention concerne un procédé d'impression 4D comportant les étapes consistant à déposer une couche de filaments dans un agencement prédéterminé sur un substrat souple. Chaque filament comporte une matrice en hydrogel et une pluralité de particules de remplissage anisotropes enrobées dans celle-ci. Les filaments sont en contact avec le substrat souple dans une ou plusieurs régions de contact. La couche de filaments est hydratée et les filaments se dilatent tout en restant en contact avec le substrat souple au niveau des régions de contact. Le substrat souple est ainsi amené à adopter une forme incurvée prédéterminée.
