Silicone elastomers have broad versatility within a variety of potential advanced materials applications, such as soft robotics, biomedical devices, and metamaterials. A series of custom 3D printable silicone inks with tunable stiffness is developed, formulated, and characterized. The silicone inks exhibit excellent rheological behavior for 3D printing, as observed from the printing of porous structures with controlled architectures. Herein, the capability to tune the stiffness of printable silicone materials via careful control over the chemistry, network formation, and crosslink density of the ink formulations in order to overcome the challenging interplay between ink development, post‐processing, material properties, and performance is demonstrated.

具有可调刚度的定制3D可打印有机硅

有机硅弹性体在各种潜在的高级材料应用（例如软机器人，生物医学设备和超材料）中具有广泛的多功能性。开发，配制和表征了一系列具有可调刚度的定制3D可打印有机硅油墨。如从具有受控结构的多孔结构的印刷中观察到的那样，有机硅油墨对3D打印显示出优异的流变行为。这里，通过克服油墨配方的化学性质，网络形成和交联密度来调节可印刷有机硅材料的刚度的能力是为了克服油墨开发，后处理，材料性能和性能之间的挑战性相互作用。演示。
