Abstract

This article outlines the key concepts of filament preparation and printing of metal-filled polymer composites through FDM technology. Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) uses the idea of melting the material and depositing it layer by layer. The filament for this process is usually prepared by mixing the metal powder in a polymer. The extrusion method is usually the preferred way to fabricate the filament, however, the procedure for mixing polymer and metal depends on the polymer. In this article, the main processes behind various combinations; of PLA, ABS, and PVB as polymers and Aluminium, Copper, Iron, Steel, Nickel, and Ceramics as fillers have been discussed. It is concluded that this technology can have a wide range of applications from aerospace, energy storage, medicine, education, etc… Possible future prospects for further research have also been highlighted.
