Development of new nanocomposites for 3D printing applications

Two emerging research area such as nanotechnology and additive manufacturing (AM) can synergically interact with mutual benefits. In fact, nanotechnology can lay the basis for new materials with superior mechanical and functional properties that could revolutionize several fields, while AM is providing the abilities to fabricate products with high geometrical complexity, shorter manufacturing time and low-cost. In this chapter, the state of the art of the use of polymeric nanocomposites in AM will be reviewed. Various materials formulation and popular AM methods such as materials extrusion (i.e. fused filament fabrication and liquid deposition modelling), selective laser sintering and stereolithography will be discussed. Emphasis is paid to the performances (mechanical, electrical and thermal) of AM products obtained by using nanocomposites and their prospective applications.
