Aluminum housing, hardened steel drive train, larger drive wheels for maximum filament grip, and a 30mm pancake stepper motor. Everything that made the LGX popular, rebuilt without compromise for demanding environments and abrasive filaments.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/www.bondtech.se\/wp-content\/uploads\/2024\/04\/bondtech_EXT01LGX41036_LGX-PRO-Metal-eXtruder_3750x2500-1200x800.jpg\" alt=\"Bondtech LGX Pro Metal extruder 1.75mm full metal dual drive with 30mm pancake motor\" style=\"width:100%;height:auto;\"\u003e\n\n\u003ch3\u003eFull Metal — Why It Matters for High-Temperature Printing\u003c\/h3\u003e\n\u003cp\u003eStandard extruder housings use injection-molded plastic that softens and deforms in sustained high-temperature chamber environments — exactly the conditions required for ABS, ASA, PA, PC, and fiber-reinforced materials. The LGX Pro Metal replaces the housing with aluminum, eliminating heat creep deformation at the extruder body and providing a rigid mounting platform that doesn't flex under the load of a heavy direct-drive hotend. The full hardened steel drive train handles abrasive filaments — carbon fiber, glass fiber, and similar composites — without wearing down the drive surface over time.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/www.bondtech.se\/wp-content\/uploads\/2024\/04\/bondtech_EXT01LGX41036_LGX-PRO-Metal-eXtruder-4_3750x2500-1200x800.jpg\" alt=\"Bondtech LGX Pro Metal extruder detail view aluminum housing hardened steel drive train\" style=\"width:100%;height:auto;\"\u003e\n\n\u003ch3\u003eDual Drive with Large Gears — More Grip, Higher Feed Rates\u003c\/h3\u003e\n\u003cp\u003eBondtech's Dual Drive Technology grips the filament from both sides simultaneously, doubling the contact surface compared to single-drive designs. The LGX uses larger-diameter drive wheels than standard dual-drive extruders, which increases the grip surface area further and reduces the risk of filament grinding under high-torque loads. The result is higher maximum feed rates, more consistent push force at speed, and better performance with flexible filaments that single-drive and small-wheel designs struggle with.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAluminum housing\u003c\/strong\u003e — rigid, heat-resistant, suitable for enclosed high-temperature chambers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull hardened steel drive train\u003c\/strong\u003e — handles abrasive filaments without gear wear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger drive wheels\u003c\/strong\u003e — increased filament contact and grip surface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e30mm NEMA17 pancake stepper motor\u003c\/strong\u003e — strong output in a compact, lightweight package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNew filament pre-tension lever\u003c\/strong\u003e — open position plus 4 indexed positions for repeatable, consistent results across filament types\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-function interface socket\u003c\/strong\u003e — quick swap between tool or application configurations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAluminum Interface Plug\u003c\/strong\u003e — supports longer hotends that standard plastic plugs can't accommodate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMultiple mounting hole patterns\u003c\/strong\u003e — flexible installation across printer platforms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact, symmetric design\u003c\/strong\u003e — reduced toolhead mass, improved performance at high accelerations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDust and particle protection\u003c\/strong\u003e — improved sealing for industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFilament Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.75mm only\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrive Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDual Drive — large gears, hardened steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHousing Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrive Train\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull hardened steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMotor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCustom NEMA17 30mm pancake stepper\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMetal Push-in M7 4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePre-Tension\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4-position indexed lever + open position\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInterface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMulti-function socket — quick swap compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMultiple hole patterns — flexible platform compatibility\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1× LGX Pro Metal 1.75mm feeder\u003c\/li\u003e\n  \u003cli\u003e1× Custom NEMA17 30mm pancake stepper motor\u003c\/li\u003e\n  \u003cli\u003e1× Metal Push-in fitting M7 4mm\u003c\/li\u003e\n  \u003cli\u003e1× 2mm Hex Key\u003c\/li\u003e\n  \u003cli\u003e4× M3×23mm studs with 5mm hex and M3×4 thread\u003c\/li\u003e\n  \u003cli\u003e1× 30mm PTFE tube for Direct Drive Interface Plug\u003c\/li\u003e\n  \u003cli\u003e1× Powered By Bondtech sticker\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n\u003cp\u003eThe LGX Pro Metal is the right choice for builders running enclosed chambers at sustained high temperatures, printing abrasive engineering filaments regularly, or pushing feed rates where standard extruders start grinding or slipping.
