Abstract Scope |
The fabrication of electronic devices and embedded circuitry components requires functional materials beyond those typically used in 3D-printing for rapid prototyping and the production of end-use structural parts. For ink-based additive manufacturing, this functionality is often achieved through electronically-active nanofillers dispersed within solvents or polymeric resins. Continuous-flow hydro- and solvothermal production methods generate a wide variety of functional nanomaterials; the particles are suspended in solution and delivered at scale, with a high degree of control over product characteristics, rendering this synthesis approach complementary to functional ink formulation work. Here, a counter-current nozzle reactor within a bench-scale sub/supercritical continuous-flow system is used to synthesise a range of nanoparticles with desirable electronic properties, including magnetic and dielectric materials. In-flow surface functionalisation is explored, enabling immediate and stable dispersion of the synthesised particles within various solvents and UV-curable resins. The resultant inks were successfully printed using both material jetting and vat photopolymerisation techniques. |
