Nozzle Swapout

[Ryantruran 0]

Can the nozzle be swapped out on the Ultimaker 3 or do you have to buy a new core every time a nozzle wears out?

No. Yes. And welcome to the forum

what is the hangup on replacing the nozzle? is it that the nozzle will physically not unscrew from the element?

Its insane to me that ultimaker would take a step back and prevent nozzle swapouts in exchange for more expensive printer core swapouts. Many users printing with carbon filled filaments go through brass nozzles like crazy.

You know what, I thought almost the same at first. But there are reasons to this. For example they do a precision Core that is (afaik) drill on one piece, so the extrusion is sweet and precise.

Also there's a big problem that none other has solved and it's the calibration. If you could swap nozzles every time you do it you would have to recalibrate the offset from each Core. And that's 17-20minutes.

Physically if you could make the nozzle it could be possible to swap it but it takes a highly skilled guy to disassemble a Core with good tools and isn't something the common user could do.

So it's a problem? Well not really since Core lifetime is muuuuch higher, but also atm you can't just use abrasive materials. Clearly UM3 is focused (atm) for printers that need PVA for supports and good and constant repetition. So, it can bug some, but does make sense that it can't be swapped just like a um2+.
