摘要：
It has been challenging to develop a new functional material with high conductivity for the Fused Filament Fabrication (FFF) based 3D printing technology. The proposed low-melting metal alloy filament provides the key to overcome the challenges including printability and conductivity. For this report, two metal alloys are designed to evaluate their suitability for FFF. In order to achieve material compatibility of the designed filament material with the nozzle materials, different nozzle materials are also investigated using thermal analysis. Then, a custom extrusion nozzle is suggested using thermal modeling to optimize the melt-zone for reliable extrusion. And finally, 3D printed circuit is demonstrated from a 3D printed plastic case to the integrated printed-alloy connections for the light-emitting device.
