摘要：
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.
