With the V4 Extruder Upgrade kit, you can reach higher temperatures (up to 300 °C) while also reducing your material's residence time at elevated temperatures.

In addition to all necessary installation hardware, the V4 Extruder Upgrade Kit includes:

• 1 - Optimized Z Endstop Clamp
• 1 - V4 Hot End
• 1 - V4 Filament Drive with Rev F/G fan cooling
• 1 - V4 Mounting Plate with Rev F/G cooling system

* This upgrade kit is compatible only with M2 3D printers purchased after November 2013 or with earlier M2 3D printers that have already installed the 24 V Power Supply Upgrade Kit. If you purchased your M2 3D printer before November 2013 but have not installed the 24 V Power Supply Upgrade Kit, our "Standard PLUS" Power Supply Upgrade Kit includes both products bundled together.
