Nozzle Swapout

Recommended Posts

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+.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
