3D打印技术已被广泛用于水凝胶的快速设计和制造，以满足复杂的软结构和设备的要求。在这里，提出了一种新的3D打印方法，基于卡波姆的流变改性剂，用于各种功能性水凝胶的直接墨水书写。卡波姆在为多功能水凝胶墨水提供理想的流变行为方面表现出高度的效率，包括双网络水凝胶、磁性水凝胶、温度敏感性水凝胶和凝胶，记录的剂量低（至少0.5%w/v）。除了出色的打印性能、机械行为和生物相容性外，3D打印的多功能水凝胶还可以实现各种软设备，包括可折叠网络、软机器人、4D打印叶子和水凝胶培养皿。此外，凭借其前所未有的能力，基于卡波姆的3D打印方法为生物打印制造和集成水凝胶设备开辟了新的途径。
3D printing technology has been widely explored for the rapid design and fabrication of hydrogels, as required by complicated soft structures and devices. Here, a new 3D printing method is presented based on the rheology modifier of Carbomer for direct ink writing of various functional hydrogels. Carbomer is shown to be highly efficient in providing ideal rheological behaviors for multifunctional hydrogel inks, including double network hydrogels, magnetic hydrogels, temperature-sensitive hydrogels, and biogels, with a low dosage (at least 0.5% w/v) recorded. Besides the excellent printing performance, mechanical behaviors, and biocompatibility, the 3D printed multifunctional hydrogels enable various soft devices, including loadable webs, soft robots, 4D printed leaves, and hydrogel Petri dishes. Moreover, with its unprecedented capability, the Carbomer-based 3D printing method opens new avenues for bioprinting manufacturing and integrated hydrogel devices.
