3D Printing of a Self-Healing Thermoplastic Polyurethane through FDM: From Polymer Slab to Mechanical Assessment

The use of self-healing (SH) polymers to make 3D-printed polymeric parts offers the po-tential to increase the quality of 3D-printed parts and to increase their durability and damage toler-ance due to their (on-demand) dynamic nature. Nevertheless, 3D-printing of such dynamic poly-mers is not a straightforward process due to their polymer...

Effect of diisocyanate mixtures on the healing of thermoplastic polyurethanes

Self-healing materials and, in particular, polymers are characterized by their ability to partially or fully restore their original properties or functions after damage. Amongst the healable polymer classes, thermoplastic polyurethanes have received increasing attention in the last years. This is mainly due to their broad application areas, the...

Additive manufacturing of a self-healing thermoplastic polyurethane

Additive manufacturing of smart polymers is a rapidly growing field. Additive manufacturing presents a versatile, low-waste manufacturing method for functional materials. Self-healing polymers are a type of smart polymers that are able to mend damage, either by the incorporation of an encapsulated healing agent or by intrinsic polymer design....
