From Bondtech and Slice Engineering

This LGX ACE Magnum+ is a special short filament path hotend jointly developed by Bondtech and Slice Engineering that can be used with the LGX extruder. It features Slice's Mosquito Magnum+ bi-metal heatbreak technology and an industrial-grade copper heating block for improved thermal performance and melt flow capacity.

Combined with the LGX extruder, the result is an industrial-grade printhead that excels at printing ALL common materials, especially soft and flexible materials.

Key features of the LGX ACE Magnum+

  • Robust high-flow hotend
  • Enables industrial-level volumetric flow rates
  • Supports rigid, flexible and soft materials
  • Prints flexible and soft materials faster
  • Easy to cool down and install
  • 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 ACE Mosquito, the LGX ACE Magnum+ delivers a significant boost compared to the full Mosquito Magnum+ hotend.

Improved cooling performance

The LGX ACE Magnum+ Hotend features a monolithic air-cooled heatsink and cooling block designed and manufactured by Bondtech, which connects to the LGX extruder through its interface connector, which is located at 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.
