| Description | L'invention concerne une matière support destinée à être utilisée dans un système de fabrication additive comprenant un copolymère de monomères de vinylpyrrolidone (VP) et de monomères élastomères. Les monomères élastomères et les monomères de VP sont liés par covalence et copolymérisés. La matière support est thermiquement stable même à des températures supérieures à 80 °C, et est capable de se désintégrer dans des solutions aqueuses comme l'eau du robinet. |
| Abstract | A support material for use in an additive manufacturing system includes a copolymer of vinyl pyrrolidone (VP) monomers and elastomeric monomers. The elastomeric monomers and the VP monomers are covalently bonded and copolymerized. The support material is thermally stable even at temperatures above 80°C and is disintegrable in aqueous solutions such as tap water. |
