is the ultimaker 2 hotend all metal?

what components of a hot end are not metal in a hot end that isnt all metal? are there pros and cons for each?

Here's a link to what makes up the hot end on the UM2.

Basically only the PTFE coupler is the only non-metal component.

In our experience, all metal hotends don't work very with PLA. As they are prone to jamming with PLA. If you just want ABS and other materials, then all metal can work fine. But for PLA it's hell.

(We've spend a LOT of time trying to get a all metal hotend to work for the UM2. Never worked up to our standards)

are you planning the development of an all metal extruder as kit for ultimaker 2?

I think it that would be a good idea, so it would no longer have to resort to third-party products (E3d...) since for nylon, abs, xt the metal way seems to be the best.

On other hand supply only one type of extruder for all types of filaments is perhaps a difficult way...
