Every structural and mechanical component has been upgraded: steel\n  replaces plastic in the drive train, aluminum replaces printed housing, and the large\n  gear Dual Drive geometry is retained for the grip and feed consistency that made the\n  LGX platform a benchmark for precision extrusion.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003e1.75mm filament only.\u003c\/strong\u003e This extruder does not support 2.85mm.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eNo mount plate between motor and extruder body.\u003c\/strong\u003e The LGX PRO\n  Metal does not accept an adapter plate between the stepper and the feeder — direct\n  motor mounting only.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eMotor stud threads are aluminum — use finger force only.\u003c\/strong\u003e\n  The M3x23mm mounting studs thread into aluminum.

The LGX PRO Metal replaces the entire drive train with \u003cstrong\u003efull steel\n  components\u003c\/strong\u003e — harder, more dimensionally stable under thermal stress, and\n  significantly more resistant to wear from abrasive filaments like CF, GF, and\n  particle-loaded composites. The steel drive train is what enables this extruder\n  to sustain consistent grip force and precise feed rates across long production runs\n  without the gradual performance degradation that plastic components experience.\n\u003c\/p\u003e\n\n\u003ch3\u003eBondtech Dual Drive Technology — Large Gear Geometry for Maximum Grip\u003c\/h3\u003e\n\u003cp\u003e\n  All LGX extruders are built on Bondtech's \u003cstrong\u003eDual Drive Technology with\n  large diameter drive gears\u003c\/strong\u003e — the design that distinguishes the LGX platform\n  from BMG and similar compact dual-drive designs. Larger drive gears increase the\n  filament contact arc, distributing grip force over a larger surface area rather than\n  a concentrated pinch point. The result is more consistent filament engagement,\n  reduced slippage on flexible and abrasive materials, and lower risk of grinding\n  even when running at elevated feed rates. On the PRO Metal, this geometry is\n  implemented entirely in steel for the contact components — combining the large\n  gear advantage with the durability of metal at every wear point.\n\u003c\/p\u003e\n\n\u003ch3\u003eAluminum Housing — Higher Thermal and Mechanical Resistance\u003c\/h3\u003e\n\u003cp\u003e\n  The LGX PRO Metal uses an \u003cstrong\u003ealuminum housing\u003c\/strong\u003e rather than the nylon\n  housing of the standard LGX. Aluminum provides significantly higher thermal\n  resistance — critical for enclosed high-temperature printing environments where\n  chamber temps can reach 60–80°C and the extruder body must maintain dimensional\n  stability throughout. Aluminum also offers better protection against\n  \u003cstrong\u003edust and particle-saturated industrial environments\u003c\/strong\u003e where printed\n  nylon housings can absorb moisture or degrade over time. The result is an extruder\n  that maintains its fit and mechanical precision across more demanding operating\n  conditions.\n\u003c\/p\u003e\n\n\u003ch3\u003ePre-Tension Lever with 5 Presets — Calibrated Grip for Any Filament Type\u003c\/h3\u003e\n\u003cp\u003e\n  The LGX PRO Metal includes the same \u003cstrong\u003epre-tension mechanism with 5 selectable\n  presets\u003c\/strong\u003e as the standard LGX — open, rigid, hard rigid\/semi-flexible,\n  flexible, and soft flexible. Each preset adjusts the drive gear clamping force\n  on the filament to match the material's mechanical properties. Running a soft\n  TPU at the same tension as a rigid PLA-CF causes slippage or grinding; the\n  preset system removes the guesswork and lets you dial in correct tension for\n  each material type with a single lever movement.\n\u003c\/p\u003e\n\n\u003ch3\u003eAluminum Interface Plug — Included Free, Supports Longer Hotends\u003c\/h3\u003e\n\u003cp\u003e\n  Every LGX PRO Metal ships with a \u003cstrong\u003efree Aluminum Interface Plug\u003c\/strong\u003e\n  that extends the hotend mounting range to accommodate longer hotends in direct\n  drive configurations — useful when running volcano-style or extended melt-zone\n  hotends that exceed the standard mounting depth. The aluminum construction of\n  the plug matches the thermal resistance of the extruder housing.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n
