Ultimaker2 Hot-End

Recommended Posts

Before I start investigating manufacturing one myself.

Did someone already create a more generic version of the UM2 hot end that could enable to easily change the nozzle size?

Have found several topics for UM1, nothing fir UM2. Thanks!

Generally, you could use one of many hotends out there (E3D, Merlin, UBIS, and so on...).

What you need is a mount. UM1 mounts (for example for the E3D hotends) will fit the UM2, too.

Usually, there is not much need for this as the original UM2 hotend seems to be very good (I don't have one myself), hence there arent many discussions about it.

Also, you have to reconfigure the machine (build size, end stops, printhead size). I'm not sure how far the UM2 can be adjusted in comparison to the UM1 (which is highly customizable).

The hot-end is OK, but it is limited to .4

If I have to swap the full hot-end instead of just the nozzle for material changes, that's going to be time-consuming.

Not planning to do something drastically different from the current hot-end. The only thing that buggs me is that it should be easier to swap from .4 to .6 or .8 for instance.

It might slightly affect max Z-height, so not too much worried about that configuration aspect.

Alternative, is building a Kossel Mini - :) Sounds like a plan as well.

    • "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.
