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.

多功能水凝胶的3D打印

根据复杂的软结构和设备的要求，已经广泛探索了3D打印技术以快速设计和制造水凝胶。在此，提出了一种基于卡波姆的流变改性剂的新3D打印方法，用于直接书写各种功能性水凝胶。卡波姆被证明可以高效地为多功能水凝胶油墨提供理想的流变行为，包括双网络水凝胶，磁性水凝胶，温度敏感水凝胶和生物凝胶，且记录的剂量低（至少0.5％w / v）。除了出色的打印性能，机械性能和生物相容性外，3D打印多功能水凝胶还支持各种软设备，包括可加载卷筒纸，软机器人，4D打印的叶子和水凝胶陪替氏培养皿。而且，凭借其空前的能力，
