三维（3D）打印已经超越了仅仅是熔化固体的图案沉积，进入了需要空间结构软物质的领域——通常是由聚合物、胶体、表面活性剂或活细胞组成的材料。软物质的可调和动态可变的流变特性使软结构的高分辨率制造成为可能。3D打印技术采用牺牲墨水和牺牲支撑材料，在适度的力或其他小的扰动下经历可逆的固体-流体转变，利用这些流变性能。因此，可以使用牺牲材料将第二材料塑造成复杂的3D结构，然后丢弃。本文综述了用于打印软结构的牺牲材料和相关方法。我们分析了文献数据，建立了软物质印刷的制造原理，并探讨了软物质材料流变控制下的不稳定性下的印刷性能。
Three-dimensional (3D) printing has expanded beyond the mere patterned deposition of melted solids, moving into areas requiring spatially structured soft matter-typically materials composed of polymers, colloids, surfactants, or living cells. The tunable and dynamically variable rheological properties of soft matter enable the high-resolution manufacture of soft structures. These rheological properties are leveraged in 3D printing techniques that employ sacrificial inks and sacrificial support materials, which go through reversible solid-fluid transitions under modest forces or other small perturbations. Thus, a sacrificial material can be used to shape a second material into a complex 3D structure, and then discarded. Here, we review the sacrificial materials and related methods used to print soft structures. We analyze data from the literature to establish manufacturing principles of soft matter printing, and we explore printing performance within the context of instabilities controlled by the rheology of soft matter materials.
