Abstract

The process of Additive Manufacturing (AM) is the newest form of fabrication with the primary method being layer-by-layer production. The most common form of this technology is Fused Filament Fabrication (FFF), where material is deposited layer by layer to produce a highly customized part. When compared to subtractive manufacturing the production of waste is greatly reduced. This study presents some innovations on a new metal fabrication technique for FFF printing. By printing a PolyLactic Acid (PLA) compliant metal powder composite filament, a part can be made with approximately 90% metal composition and sintered. The sintering process removes the PLA bonding leaving a 100% metal part fabricated on a low cost FFF printer. Overall, this study reports the initial findings on dimensional changes in low cost metal 3D Printing process.
