Title (EN) SILICONE FORMULATIONS FOR 3D PRINTING
(FR) FORMULATIONS DE SILICONE POUR IMPRESSION 3D
Abstract:
(EN) In one embodiment, a silicone-based ink for additive manufacturing includes a vinyl-terminated siloxane macromer, a hydrophobic reinforcing filler, and a rheology modifying additive. In another embodiment, a method of additive manufacturing with silicone-based ink includes adding a mixture that includes a vinyl-terminated siloxane macromer, a hydrophobic reinforcing filler, and a rheology modifying additive to a cartridge for additive manufacturing, extruding the mixture through the cartridge to form a structure, and curing the mixture to at least a predefined extent.
(FR) Selon un mode de réalisation, l'invention concerne une encre à base de silicone pour la fabrication additive comprenant un macromère de siloxane à terminaison vinylique, une charge de renforcement hydrophobe et un additif modifiant la rhéologie. Dans un autre mode de réalisation, un procédé de fabrication additive avec de l'encre à base de silicone comprend l'ajout d'un mélange qui comprend un macromère de siloxane à terminaison vinylique, une charge de renforcement hydrophobe, et un additif modifiant la rhéologie à une cartouche pour la fabrication additive, l'extrusion du mélange à travers la cartouche pour former une structure, et le durcissement du mélange au moins dans une mesure prédéfinie.
