Direct 3D Printing of Shear‐Thinning Hydrogels into Self‐Healing Hydrogels

Supramolecular hydrogels are used in the 3D printing of high-resolution, multi­material structures. The non-covalent bonds allow the extrusion of the inks into support gels to directly write structures continuously in 3D space. This material system supports the patterning of multiple inks, cells, and void spaces. As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials are peer reviewed and may be re-organized for online delivery, but are not copy-edited or typeset. Technical support issues arising from supporting information (other than missing files) should be addressed to the authors. Please note: The publisher is not responsible for the…
