This lightweight direct-drive dual-drive extruder uses larger drive gears that significantly improves extrusion and allows for quick swapping hotends.
The Bondtech LGX Large Gears eXtruder is the first of Bondtech's filament feeders using Bondtech’s new Dual Drive Technology based on larger drive gears.
7 new features on the Bondtech LGX eXtruder:
- Larger drive wheels for increased filament grip
- Filament pre-tension lever for repeated results
- Multi-function interface socket for tool or application quick swap
- Drive wheels’ maintenance windows for easy cleaning
- Compact, light, and symmetric design for increased performance and compatibility
- Multiple mounting hole patterns for an easy and flexible setup
- A small step for a greener future: craft boxes without bleaching and no coating
The LGX can also be ordered to come with different add-ons including the LGX Shortcut and the LGX ACE. The LGX Printheads are the combination of these add-ons with the LGX.
The LGX™ Shortcut is a special hotend that mounts to the side of the LGX™ eXtruder. With the LGX™, it forms a print head that will excel at printing ALL most common materials and especially the soft and flexible. This add-on comes in two variants: Copperhead® and Mosquito®
The Bondtech LGX ACE Hotend is an add-on attachment that mounts to the front of the LGX eXtruder. The different variants (Copperhead®, Mosquito®, Mosquito® Magnum+) of the LGX ACE Hotend are designed for rigid and flexible materials, improved cooling capacity, and high flow rate applications.
