BondTech LGX ACE Copperhead Hotend

From Bondtech and Slice Engineering

The LGX ACE Copperhead Hotend is a dedicated short filament path hotend developed by Bondtech and Slice Engineering to be used with the LGX extruder .

It features Slice's Copperhead bimetal heatbreak technology and a copper heater block for improved thermal performance.

In combination with the LGX extruder, a print head is created that can process ALL common materials and especially soft and flexible materials.

Key Features

• 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 print head

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

Improved cooling performance

The LGX ACE Copperhead Hotend features a monolithic air-cooled heatsink and heatsink designed and manufactured by Bondtech, which connects to the LGX extruder through its interface connector and 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 heatsink are monolithic, which increases heat transfer and dissipation.
