Over the past few yeas there has been a great deal of interest in the development of self-healing materials with tunable structural, mechanical and rheological properties. Self-healing materials are capable to heal in response to damage whenever and wherever it occurs in the material. This unique feature makes them really attractive for applications in biomedicine, sensoring, soft robotics, and energy harvesting systems. The other great emerging and promising research field is the additive manufacturing (AM), also known as three dimensional (3D) printing, which enables to produce structures with hierarchical architectures, desired spatial arrangement, and with high degree of complexity such as hollow objects and graded or multimaterial structures.
