Designed To Be Flexible

The Bondtech LGX™ Shortcut includes a reversible heat sink that can be installed on the left or right hand side of the cold block. The heat sink also includes a hole pattern for attaching 40×40 fans.

The LGX Shortcut only supports 1.75 mm filament.

Cooling down the heat break

Bondtech's tests suggest a 4010 fan is enough to cool down the cold block and the cold zone of the heat break, even with such a small contact surface to the heat sink. In case you have an application where additional cooling is required, try using a 4020 fan or 2 LGX heat sinks, one on each side.

Compatible nozzles

The hot block included in this product is compatible with Rep Rap style nozzles, such as:

• BridgeMaster Nozzles (for peak bridging performance) 
• Vanadium Nozzles (for abrasive applications)
• CHT Coated Brass Nozzles (for high flow applications)

The LGX™ Shortcut Hotend is not compatible with the following items:

• 3DSolex Matchless 1.75mm nozzles.

By Bondtech and Slice Engineering

The Bondtech LGX ACE Hotend is an add-on attachment for the LGX eXtruder. The different variants of the LGX ACE Hotend are designed for rigid and flexible materials, improved cooling capacity, and high flow rate applications.

• Easy to cool down and install
• Supports rigid, flexible, and soft materials
• Prints flexible and soft materials faster
• Allows for higher volumetric flow rates

The LGX ACE Hotends are special short filament path hotends, co-developed by Bondtech and Slice Engineering, to be used with the LGX eXtruder. These hotends come in multiple variants including Mosquito® Magnum+, Mosquito®, and Copperhead®.

Engineered To Give More Flow

During the long months of deep testing that preceded the launch of the LGX CHT nozzles, Bondtech discovered that shortening the post-drive filament path generates increased volumetric flow rate capacity.  The LGX versions of these hotends deliver increased flow rates compared to the basic versions of these hotends.

Designed To Be Cooler

The LGX ACE Hotends feature monolithic air-cooled cold blocks and heat sinks, designed and manufactured by Bondtech, that engage with the LGX extruder using its interface plug and rest at the front of the extruder. The heat sink includes the hole pattern for attaching 40×40 fans. Bondtech's tests suggest a 4010 fan is enough to cool down the cold block and the cold zone of the heat break, due to the monolithic design of the cold block and heat sink that increases heat transmission and dissipation. 

Compatible Rep Rap Style Nozzles

• Vanadium Nozzle
• BridgeMaster Nozzle
• CHT Coated Brass Nozzle

This LGX add-on only supports 1.75 mm filament. Extruders, heaters, and thermistors are not included. Lastly, the LGX ACE Hotends are not compatible with 3DSolex Matchless 1.75 mm nozzles.

Mosquito® Magnum+

The LGX ACE Mosquito® Magnum+ Hotend is a robust high-flow hotend that allows for one-handed nozzle changes and industrial level volumetric flow rates.

Each LGX ACE Mosquito® Magnum+ Hotend includes:

• 1x LGX Black Anodized Aluminum Monolithic Cold Block and Heat Sink
• 1x Magnum+ Heat Break
• 1x Magnum+ Hot Block
• 1x Bondtech M6x1x7.5 Coated Brass Nozzle 0.4mm
• 1x Boron Nitride Paste 5ml syringe
