一般說明
聚乙烯醇（PVA）混合打印长丝是用于复杂结构的多挤压3D打印的水溶性支撑材料。该材料是不同等级PVA的混合物，可改善聚乙烯醇的热稳定性和可印刷性。除了这些改进之外，这种共混物对湿气降解的敏感性较低，同时又保持其水溶性。这种浅橙色、无味且高质量的长丝可在180至205°C的温度下挤出，适用于所有基于RepRap技术的台式3D打印机，例如MakerBot、Ultimaker、RepRap（Mendel、Huxley、Prusa）、UP、Solidoodle、Leapfrog等。这种PVA混合长丝对多种材料（如PLA、ABS、PETG、ASA、HIPS和尼龙）具有良好的黏附性，并且在水中可生物降解，不会产生有害的副产物。尽管PVA可溶于冷水，但使用连续加热的温水浴可以加速溶解过程。在不使用时，应将长丝储存于室温下干燥处，如密封在塑料袋中或装有干燥剂的密闭容器中。关于推荐的初始打印机设置，参阅“常规打印设置”文件。
應用

由于其水溶性和生物相容性，聚乙烯醇（PVA）长丝最常被用作形成具有独特和复杂结构的组织工程构造的牺牲材料。利用这种材料，可以打印具有大凸头、深内腔和/或复杂几何形状的支架。除了用作牺牲材料外，PVA长丝还被用于打印新型口服药物递送装置和片剂。

Fused deposition modeling (FDM) is a 3D printing technique based on the deposition of successive layers of thermoplastic materials following their softening/melting. Such a technique holds huge potential for the manufacturing of pharmaceutical products and is currently under extensive investigation.
