BondTech LGX ACE Copperhead Printhead

From Bondtech and Slice Engineering

The LGX ACE Copperhead Printhead is a dedicated short filament path printhead jointly developed by Bondtech and Slice Engineering that incorporates the LGX extruder.

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

The LGX based print head is excellent for printing ALL common materials, especially soft and flexible filaments.

Key features of the LGX ACE Copperhead Printhead

• Easier to cool & assemble
• Allows a higher flow rate
• Supports rigid, flexible and soft materials
• Prints flexible and soft materials faster
• It is small and light

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 Copperhead Hotend, the LGX ACE Copperhead Hotend offers the same increase compared to the full Copperhead hotend.

Improved cooling performance

The LGX ACE Copperhead Printhead features a monolithic air-cooled heatsink and heatsink designed and manufactured by Bondtech that 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 cooling block are monolithic, which increases heat transfer and dissipation.
