Additive Manufacturing (AM) unlocked a new way of producing advanced structures that are stronger and use less material, enabling new possibilities due to design freedom, easiness of manufacturing complex parts, and mass personalization. One of the most common AM processes is Fused Filament Fabrication (FFF), which is mainly used to manufacture polymer parts. However, FFF can also produce metallic components, which is not as simple and direct since it requires debinding and sintering processes. This study was conducted to develop the knowledge of FFF using metal and aims to evaluate the characteristics of D2 tool steel. The mechanical and microstructural properties were evaluated, and the results were compared with the supplier's datasheets.
