Hi, I have an anycubic i3 mega s, and I wanted to print with ABS. I read an article about not printing above 240 °C (464 °F) with a Teflon/PTFE hotend because it melts the PTFE and releases very toxic fumes.
Does anyone know if stock anycubic i3 mega s have PTFE hotends?

Yes it has

#

You need to get a all metal heatbreak

#

And for abs it is also important to have an enclosure
