Hemiaminal poly(ethylene glycol) (PEG)‐based organogels are formulated in polymerizable solvents. The dynamic‐covalent nature of the solvent‐H‐bonded hemiaminal crosslinks, together with the modification of the crosslinking density of the organogels allows for temperature‐dependent viscoelastic control. The shape of uncured gels can be permanently retained by templated UV‐curing of the solvent, offering great promise for complex manufacturing, printing, sealants, and materials repair.
