More Information
Summary:Provided are polymer compositions and methods of making 3D structures. The polymer compositions include a polymer component (e.g., siloxane polymer) having a plurality of vinyl groups and a polymer component (e.g., siloxane polymer) having a plurality of thiol groups. The polymer compositions can be used to form elastomeric 3D structures. Also provided are 3D printers having an exposure window comprising a film of an organic polymer disposed on the outer surface of the exposure window. L'invention concerne des compositions polymères et des procédés de fabrication de structures 3D. Les compositions polymères comprennent un constituant polymère (par exemple un polymère de siloxane) présentant une pluralité de groupes vinyle et un constituant polymère (par exemple un polymère de siloxane) présentant une pluralité de groupes thiol. Les compositions polymères peuvent être utilisées pour former des structures 3D élastomères. L'invention porte également sur des imprimantes 3D présentant une fenêtre d'exposition comprenant un film d'un polymère organique disposé sur la surface externe de la fenêtre d'exposition.
