Abstract Scope |
Fused Filament Fabrication (FFF) is an additive manufacturing technology also applied to indirect printing of metal parts recently. This involves the use of composite filaments compounded with metal powder and polymer binders. The as-printed samples (green parts) are then debinded and sintered to obtain a fully dense metal component. In this study, we investigate FFF printing of copper. The target is to reach ≥ 96% relative density in the sintered state. A full factorial design of experiments with layer thickness, flowrate multiplier and nozzle travelling speed was conducted to investigate the printing process. Debinding and sintering were applied subsequently. Multiple tests, including Archimedes method, micro- CT, SEM inspection, analysis of variance, TGA, etc. were applied at different stages to study the quality of filament, printing and post processing. As a result, it was feasible to fabricate 96% dense copper component with FFF. |
