Abstract

Fused Filament Fabrication (FFF) is the most common additive manufacturing technique for the production of polymeric components, mainly due to its simplicity and the lower cost of equipment. By the use of feedstocks similar to those of Powder Injection Moulding (PIM), the FFF of metallic and ceramic components is possible. The feedstocks are used in form of a filament, which imposes a set of requirements such as the flexibility to be spooled, stiffness to avoid buckling and a constant diameter to ensure a constant mass flow. In our research the production of metallic and ceramic components by combining FFF and SDS has been carried out and the properties required in the material have been studied. Filaments were prepared by compounding multicomponent thermoplastic binders with different powders. Measurements were done for the viscosity of the feedstocks, the mechanical properties of the filaments by tensile tests and the printability in FFF machines. For the removal of the organic components, solvent debinding by immersion in a hydrocarbon was studied.
