Hydrogels represent a versatile class of biomaterials with unique properties that have sparked significant interest across various fields. In particular, they have emerged as promising candidates for numerous biomedical applications thanks to their biocompatibility, tunable mechanical properties and ability to mimic biological tissues. Self-healing hydrogels are biomaterials that can repair structural damage and recover their properties, similarly to human tissues. This characteristic makes these kinds of materials able to restore the morphology and mechanical properties after being damaged, thereby extending their lifespan and maintaining their structural integrity and functionality over time. The aim of the work is to investigate a self-healing hydrogel based on a resin which can be 3D printed via Digital Light Processing (DLP).
