Although the application of cleaned tungsten wire in 3D printing technology is not as common as tungsten powder, it holds unique potential:
- Metal 3D Printing Feedstock: Cleaned tungsten wire can serve as wire feedstock for laser or electron beam melting 3D printing, enabling the fabrication of high-density, high-strength tungsten-based parts for applications in aerospace (such as nozzles) or high-temperature molds.
- Arc 3D Printing Electrode: In arc additive manufacturing, cleaned tungsten wire is used as a non-consumable electrode to generate a stable arc that melts metal powder or wire, suitable for rapid prototyping of large metal components.
- Auxiliary Components: In 3D printing equipment, cleaned tungsten wire can be used as a reinforcement material for high-temperature nozzles or as heating elements, owing to its wear resistance and high-temperature durability.
Currently, the primary form of tungsten in 3D printing remains powder, but the application of cleaned tungsten wire in high-precision or specialized processes is under research and development, with potential for greater impact in the future printing of miniature high-performance parts.
