RepRapDiscount, Hexagon Full Metal Hot End, Hotend, 1.75mm, .4mm nozzle

The Hexagon Hotend is all metal, so you can experiment with filament materials that require hotter temperatures like nylon and polycarbonate and still be confident when you print in PLA or ABS.

The Hexagon is far more durable than plastic body hotends. PTFE Liners often swell, forcing cracks in the plastic bodies or pushing the heater block off. This ruins your print and your day. Since the Hexagon is all metal and has no PTFE liner, it is immune to this type of failure.

Many of the metal hotends on the market are a centimeter longer than a typical PEEK J-Head hotend, sacrificing a centimeter of print height. The RepRapdiscount Hexagon hotend is only 55mm in length and only weighs 25g, so it is actually shorter and lighter than most of the popular plastic hotends on the market.

The nozzle can be removed and replaced without dismounting the hotend from the printer. Other nozzle sizes are available.

You may want to purchase kapton tape and high temp RTV to aid in assembling your hotend. A printed fan shroud for the Hexagon cooling fins is recommended. Everything else you need is included in the kit.

You MUST use a fan with this hotend. Without a fan, heat can travel up the Hexagon body and melt filament before it reaches the heater block. This will cause a printer jam. Configured properly with a fan, your Hexagon should function flawlessly.
