聚乙烯醇(PVA)打印长丝是一种水溶性支撑材料,用于复杂架构的多挤出3D打印,PVA广泛应用于传统行业,如纺织和造纸,以及各种涂料,这种无色无味的高品质长丝在180至205 °C之间挤出,适用于所有基于RepRap技术的桌面3D打印机,如MakerBot、Ultimaker、RepRap等(孟德尔,赫胥黎,普鲁沙),起来!、Solidoodle、Leapfrog等。聚乙烯醇对聚乳酸及尼龙材料有良好的附着力,在水中可生物降解,不会产生有害的副产物。聚乙烯醇溶于冷水,但可使用持续加热的温水浴加速溶解过程。不使用时,灯丝应在室温干燥条件下储存,如在密封塑料袋或装有干燥剂的密闭容器中。建议的打印机初始设置可在“通用打印设置”文件中找到。
Due to its water-solubility and biocompatibility, polyvinyl alcohol (PVA) filaments are most commonly used as a sacrificial material in the formation of tissue engineering constructs with unique and complicated architectures.PMID 26117791PMID 27607243PMID 26991636 The use of this material allows for the printing of scaffolds with large overhangs, deep internal cavities, and/or intricate geometries. In addition to their use as sacrificial materials, PVA filaments have also been used to print novel oral drug delivery devices and tablets.PMID 26473653PMID 28250279PMID 27215535
