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 optionalpolyol component. 本发明涉及用于口腔护理或医疗装置，组件和应用的固体自由形式制造的组合物和方法，其中所述组合物包括特别适用于这种加工的热塑性聚氨酯。有用的热塑性聚氨酯衍生自(a)芳族二异氰酸酯组分，(b)扩链剂组分和任选的多元醇组分。
