Ender-3 and Novice Upgrades: Eighth Upgrade (Hotend)
This text has been automatically translated using Google Translate.
The eighth upgrade is again a major intervention in the printer and is absolutely not needed. It will help quiet your printer, eliminate some problems and make your life easier. A little bit, but better than nothing.
What is it about?
HOTEND ! Yes! Finally hotend! :)
If you replace the existing hotend with an E6 V6, you will be able to use a fan with less force thanks to the larger heat sink. A less powerful fan means less noise.
Moreover, thanks to the huge expansion of this hotend you can buy it for a few crowns.

| Cheaper variant | More expensive variant |
| about 120 CZK | about 400 CZK |
| This variant is kind of on the border below which I would not go. It may even happen that the dimensions are not entirely identical to the dimensions it has in the E3D documentation. | Significantly more expensive, but very well processed hotend created according to E3D documentation. |
When deciding to come across different types of heatbreak.
| All metal | Bore | PTFE lining |
|---|---|---|
| It is all-metal heatbreak. This allows you to print at higher temperatures than the PTFE limitation. Unfortunately, PLA has problems with this heatbreak, because a large temperature jump will cause the filament to cool down, and then the filament cannot pass back into the nozzle. | This type of heatbreak is hollow and requires a PTFE tube. With this design, you can have a PTFE tube from the extruder to the nozzle without interruption. | The same restrictions apply to this version as the Bore version. The main difference is in the thinner wall of the PTFE tube and in the separation of the inlet PTFE from the outlet PTFE that leads to the nozzle. |
