Bondtech LGX ACE Copperhead printhead

The LGX ACE Copperhead printhead is the result of a collaboration between Bondtech and Slice Engineering. It features Bondtech's LGX large gear extruder, and the Slice Engineering Copperhead bimetallic heatbreak and copper industrial grade hotblock. The complete list of elements includes:

• The LGX large gears extruder.
• The LGX ACE Copperhead hotend:
  • 1x LGX monolithic cold block and heat sink (black anodized aluminum).
  • 1x Copperhead LGX heatbreak.
  • 1x Copperhead hot block.
  • 1x Bondtech M6x1x7.5 coated brass nozzle (0.4 mm).
• 1x silver-based thermal paste (0.5 g sachet).

It must be kept in mind that no heater or thermistor are included in this printhead assembly.

With this printhead, the aim was to create an industrial-grade printhead that would work with rigid as well as soft and flexible materials, and the LGX ACE Copperhead printhead does just that. The LGX extruder's special design offers a short filament path, and the Slice Engineering technology ensures improved thermal performance and melt flow capacity. Furthermore, the Bondtech monolithic cold block and heatsink design guarantee increased heat transmission and dissipation (more efficient cooling).

The LGX ACE Copperhead printhead only supports 1.75 mm filament and is compatible with the Bondtech standard brass, standard coated brass, and CHT coated brass nozzles, as well as the Slice Engineering BridgeMaster copper nozzle and the vanadium steel nozzle for abrasive filaments. The LGX ACE Copperhead printhead is not compatible with the 3DSolex Matchless 1.75 mm nozzles.

Installing the LGX ACE Copperhead printhead has numerous advantages. Apart from an increased flow (and faster printing with flexible materials) and a wide range of printable materials, this printhead offers a more efficient cool-down, it is easy to install and allows for one-hand nozzle change.
