Abstract | An apparatus (100) for additive manufacturing of a part includes a print bed (200) including a build sheet (220), a print head/nozzle system (300), and a physical control system (400) providing for relative motion between the print head/nozzle system and the print bed. The build sheet includes a foam material having a glass transition temperature of at least about 140 °C, or 80 wt% to 99 wt% of a cellulose fiber material and from 0.5 wt% to 10 wt% of a binder. The print head/nozzle system includes at least one print head and nozzle and is configured to apply an additive manufacturing material (330) onto the print bed. In some aspects the build sheet includes a reinforcing substrate. In further aspects a method for additive manufacturing a printed part includes applying a plurality of layers (340) of an additive manufacturing material onto a print bed to form the printed part.
L'invention concerne un appareil de fabrication additive d'une pièce qui comprend un lit d'impression comportant une feuille de construction, un système tête/buse d'impression et un système de commande physique permettant un mouvement relatif entre le système tête/buse d'impression et le lit d'impression. La feuille de construction comprend un matériau en mousse ayant une température de transition vitreuse d'au moins environ 140 °C ou de 80 % en poids à 99 % en poids, d'un matériau à base de fibre de cellulose et de 0,5 % en poids à 10 % en poids d'un liant. Le système tête/buse d'impression comprend au moins une tête et une buse d'impression et est conçu pour appliquer un matériau de fabrication additive sur le lit d'impression. Selon certains aspects, la feuille de construction comprend un substrat de renforcement. Selon d'autres aspects, un procédé de fabrication additive d'une pièce imprimée comprend l'application d'une pluralité de couches d'un matériau de fabrication additive sur un lit d'impression pour former la pièce imprimée. |
