BondTech LGX ACE Mosquito Hotend, 1,75 mm

From Bondtech and Slice Engineering

The LGX ACE Mosquito is a dedicated short filament path hotend co-developed by Bondtech and Slice Engineering.

The hotend features Slice's Mosquito bi-metal heatbreak technology and a copper heater block for improved thermal performance. In combination with the matching LGX extruder, a print head is created that can excellently print all common materials and especially soft and flexible filaments.

⇒ Attention!

• The 1.75 mm hotend can be used with the LGX eXtruder or in combination with the 1.75 mm version of the LGX Pro eXtruder.
• The 2.85 mm hotend can be used in combination with the 2.85 mm variant of the LGX Pro eXtruder.

Key features of the LGX ACE Mosquito:

• It is easier to cool down and assemble,
• Enables a higher volume flow,
• Supports rigid, flexible and soft materials,
• Prints flexible and soft materials faster,
• Forms a small and light but robust print head,
• Allows you to change nozzles with one hand.

Designed to provide more flow

During the long months of intensive testing leading up to the launch of the LGX CHT nozzles, Bondtech discovered that shortening the post-drive filament path results in increased volumetric flow capacity. Similar to the LGX Shortcut Mosquito, the LGX ACE Mosquito Hotend offers the same boost compared to the full Mosquito hotend.

Improved cooling performance

The LGX ACE Mosquito Hotend features a monolithic air-cooled cooling block and heatsink, designed and manufactured by Bondtech, which connects to the LGX extruder via its interface connector and is located at the front of the extruder. The heatsink contains the hole pattern for attaching 40×40 fans.

Tip: A 4010 fan is enough to cool the cooling block and cold zone of the heatbreak because the cooling block and heatsink are monolithic, which increases heat transfer and dissipation.
