The LGX ACE Copperhead is a special short filament path printhead, co-developed by Bondtech and Slice Engineering, and includes the LGX eXtruder.

It features Slice’s Copperhead bi-metallic heat-break technology and copper hot block for improved thermal performance.

This LGX-based printhead excels at printing almost all common materials, especially soft and flexible ones.

Engineered to give more flow

During extensive testing that preceded the launch of the LGX CHT nozzles, Bondtech discovered that shortening the post-drive filament path increases volumetric flow rate capacity. Similar to the LGX Shortcut Copperhead, the LGX ACE Copperhead delivers that same increase when compared to the full Copperhead hotend.

Designed to be cooler

The LGX ACE Copperhead printhead features a monolithic air-cooled cold block and heat sink, designed and manufactured by Bondtech, that connects with the LGX extruder using its interface plug and rests at the front of the extruder. The heat sink includes the hole pattern for attaching 40×40 fans. Tests suggest that a 4010 fan is sufficient to cool the cold block and the cold zone of the heat break, due to the monolithic design that enhances heat transmission and dissipation.
