Fused Deposition Modeling printers are well-known for their versatility in printing various materials, but metal remains a challenge. Enter Rotoforge, an open source project pioneering a hot end capable of melting metal using ceramic diesel engine glow plugs, boasting temperatures of 1300°C (2372°F).
Their process involves stripping the glow plug of its metal components and delicately drilling through its ceramic tip using EDM. While metal printing isn’t yet achieved, the progress is looking promising, offering hope for future breakthroughs.
The project demonstrates innovative methods to adapt existing technology for new purposes. Despite the current limitations, the effort signifies a step forward in metal 3D printing, capturing the interest of enthusiasts and professionals alike.
Watch the accompanying video for a detailed insight into the conversion process, which involves a glow plug and an Ender 3.
Unlike previous methods reliant on MIG welders, this approach demonstrates a unique pathway toward metal printing on FDM printers.
As Rotoforge continues to refine their technique, the prospect of printing metal with standard 3D printers becomes increasingly feasible.
