Three-dimensional printing with supramolecular templated hydrogels

A supramolecular polymer composition capable of co-assembly to maintain a three dimensional (3-D) macrostructural form after 3-D printing, comprising:

• i) a solvent;
• ii) a template molecule comprising an at least partially linear amphiphilic or hydrophilic polymer;
• and
• iii) a reactive component comprising at least one monomer, wherein the monomer is capable of hydrogen bonding with the template molecule to form a 1D supramolecular structure, and wherein the monomer comprises least two pendant groups capable of covalent crosslinking;
• wherein the supramolecular polymer composition has a suitable viscoelastic property which allows for 3-D printing of the hydrogel to form a 3-D structure, and is capable of co-assembly after 3-D printing to maintain the printed three dimensional (3-D) macrostructural form;
• and
• wherein the template molecule is removable after a chemical crosslinking step.
