E3D V6 Hot End

How to tell authentic E3D hot ends? They do not have Teflon inside so they can do high temperature printing for materials that need higher temperature

"All Metal"

• The E3D All Metal hot end clone above has a Teflon liner. See thread - https://reprap.org/forum/read.php?152,556240
• Note that you can select between Teflon and no Teflon with this Ebay store - so if you have the right supplier, you will get the high temperature version? [1]

Max Temp for Teflon

• 225 C according to this thread - https://www.3dhubs.com/talk/thread/max-extruder-temp-ptfe
