Abstract Scope |
Powder metals have been used in Additive Manufacturing processes such as injection molding, extrusion, and slip casting for decades. Innovations in the Fused Filament Fabrication (FFF) process have provided the opportunity to mix powder metals with a binding thermoplastic at elevated temperatures to create good quality components. This research attempts to define the rheological characteristics of amalgam materials used to produce components at room temperature using powder metals that will provide the following three outcomes: 1. material that will flow under low shear stress, 2. green strength to provide structural support of material deposited on top and prevent deformation under gravitational load, and 3. once cured to provide material properties that are comparable to those of materials produced by traditional means. The purpose of this research is to determine if powder metal components can be produced by FFF at room temperature while maximizing the powder metal composition in the mixture. |
