<p>Slice engineering went a different way to fight heatcreep in an unined all metal hotend: The heatsink is mode away from the filament path and serves as its own structure.

Do note that many Chinese cloned hotends aren't M6 (for the whole heat break like the E3D heat breaks), although they are E3D v6 clones they are M7, hence my large spare part inventory... The threads for the heater block are indeed M6.

Can't the heat creep issue occur with all sorts of non-PLA materials too? It's probably less of an issue with very high-temp ones though.

@R..GitHubSTOPHELPINGICE it appears, but doesn't hinder the printing in the same way as in PLA.

(Asked by: username_0 on 2020-05-19)

I know that the E3D V6 hotend exists in both the all-metal V6 version, and the PTFE-lined Lite6 version with the same mount and form factor.

What other hotend designs are available like this?

A variant of the lined hotend is the Makerbot MK10, where the PTFE goes a bit into the nozzle. These nozzles have a larger diameter, the melt zone is very short.

## All Metal

There are mainly two designs of consumer all-metal hotend out there at the moment.

Stereotypical by now, the All Metal hotend typically means E3D v6. The liner ends at the end of the heartbreak, the heartbreak of the original is necked down to reduce heat creep. The design is flawed in that heat creep can't be mitigated completely. While this design can print much higher temperatures than lined hotends, the heat creep can create trouble with PLA.
