E3Dv6

E3d is a all metal hotend. Good quality parts that are serviceable. Much better than the stock hexagon.

Not terrible to install but will need some printed parts and a firmware change. Long thread on that.

@Printed Solid is the go to guy

 

better design, all replaceable (and available) spare parts (you can for example buy just the heat break)

Not a must. However if you want to do things like flexible filaments it is easier to use the E3D.\

Buy it from E3D online or from our very own @Printed Solid (printedsolid.com)

 

I'm totally on board with this. The E3D gives you a lot of good options and will be higher reliability, but if it's not broken... I think it's really a matter of properly assessing your own skills and interests. If you *like* hacking on the printer to tweak out optimal performance and capability or if your hexagon is broken then do the E3D upgrade. If not?

There was a time before the hexagon was implemented where the Robo hot end was so bad that there was no choice but to upgrade it almost immediately, but they've improved a lot since then, and some, like @Rigmarol 's will just be solid reliable hot ends. If not, E3D V6 or even the lite 6 are great options.

FWIW, we also offer an assembled version now, but I'd still encourage anyone to buy the kit; save a few bucks and understand how it is assembled.

 

Here is all I want to know about the difference, the bore of the E3Dv6 hotend is 2 mm, the bore of the Hexagon is 1.85 mm that 0.15 mm can make a big difference in the smooth flow of filament.

I would consider the E3D-Lite just like any other cheap Chinese clone and it isn't worth any amount of time or expense.
