当满足某些条件时,形状记忆聚合物可以编程为改变形状。3D 打印机可以通过将图层堆叠在一层之后来生成这些形状,从而使我们能够使任何形状变得可想而易。在这段视频中,我们将演示我们如何生产支架,这些支架在交付时可以收缩为紧凑的形式,并在正确的时刻恢复到最复杂的形状。
通过使用此方法,可以为每个患者设计定制支架,因为任何可以设计的支架都可以使用 3D 打印机进行完全制造。将近位主容器的直径设置为 25 毫米。然后,将端部主容器和侧枝的直径设置为 22 毫米。

Summary
使用 3D 打印机,将形状记忆聚合物灯丝拉伸成分支管状结构。结构是图案和形状的,这样一旦折叠,它可以收缩成紧凑的形式,然后在加热时返回到其形成的形状。
