| abstract |
The invention relates to compositions and methods for solid freeform fabrication of 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 polyisocyanate component including a first linear aliphatic diisocyate and a second aliphatic diisocyanate, a polyol component, and (c) a chain extender component. |
