  [1] |  | Iron-Filled Filament  Iron-filled filaments are PLA or ABS-based materials infused with iron powder, allowing prints to have a metallic appearance, added weight, and the ability to rust over time. These filaments can be polished to achieve metal-like finishes or intentionally oxidized for an antique, weathered effect. While printable on standard FDM printers, they are highly abrasive, requiring hardened steel or ruby nozzles to prevent excessive wear. |
