The invention relates to compositions and methods for solid freeform fabrication of oral care or medical devices, components and applications, in which the composition includes a thermoplastic polyurethane which is particularly suited for such processing. The useful thermoplastic polyurethanes are derived from (a) an aromatic diisocyanate component, (b) a chain extender component, and an optional polyol component. La invención se refiere a composiciones y métodos para la fabricación de forma libre sólida de aplicaciones, componentes y dispositivos médicos o para el cuidado bucal, en donde la composición incluye un poliuretano termoplástico que es particularmente adecuado para tal procesamiento. Los poliuretanos termoplásticos útiles se derivan de (a) un componente de diisocianato aromático, (b) un componente extensor de cadena y un componente de poliol opcional.
