From Bondtech and Slice Engineering

The LGX ACE Mosquito is a dedicated short filament path hotend co-developed by Bondtech and Slice Engineering that can be used with the LGX extruder.

It features Slice's Mosquito Bi-Metal heatbreak technology and a copper heater block for improved thermal performance. In combination with the LGX extruder, a print head is created that can excellently print ALL common materials and especially soft and flexible filaments.

Key features of the LGX ACE Mosquito

  • Easier to cool & assemble
  • Allows a higher flow rate
  • Supports rigid, flexible and soft materials
  • Prints flexible and soft materials faster
  • Forms a small and light but robust printhead
  • Allows changing nozzles with one hand

Engineered to offer higher 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 resulted in increased volumetric flow capacity. Similar to the LGX Shortcut Mosquito, the LGX ACE Mosquito hotend offers the same increase compared to the full Mosquito hotend.

Improved cooling performance

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

Bondtech's tests indicate that one 4010 fan is sufficient to cool the heatsink and the cold zone of the heat break because the heatsink and cooling block are monolithic, which increases heat transfer and dissipation.
