UM3 Compatible Small Diameter Nozzles

Recommended Posts

So I have been looking through the forum for info on smaller diameter nozzles (.25mm,.15mm) and its led me to a couple of sites with UM2 and UM2+ nozzles and I was wondering if those would also be compatible with the UM3.

If anyone has any guidance for me about which nozzles to buy from which site and if there any additional parts I would need to install them, it would be much appreciated. Also, any recommended settings for the smaller line widths would help as well.

Thanks!

Hi @Rossboss, it is true that these different nozzle sizes are compatible with the Ultimaker 2+, they are not for the Ultimaker 3.

The Ultimaker 3 has a very different designed printhead. If you have one, I am sure you have seen the print cores.

The print cores are there to make your user experience easier and more straight forward. Among other things, the Ultimaker 3 can read data from the print cores so it knows what nozzle is in there, and for what materials this is a good fit. Swapping nozzles would compromise this concept.

But we are working on different set of print cores to be added to the Ultimaker 3 parts. So you will be able to use them with a little bit of patience.

The full picture is a little bit more complex than 'just' designing a new nozzle. As part of the concept, it should also come with pre-tested and pre-configured profiles for each material, especially aimed for that print core. Hence that we did not have a full set ready at launch. But it is coming :)

Let me know if you have any further questions!

Thanks @SandervG! Glad to hear that they are in the works. If you can say, is it a matter of weeks or months?

Also if it is the better part of a year away, my employers might see it worth the risk of using a smaller nozzle on the AA core. Is there a conceivable way to make a smaller nozzle work on the AA core, or is there absolutely no chance of it working? We'd be prepared to purchase extra cores if necessary to determine the right configuration.

hmm, I would say probably somewhere in between ;) Estimation is around the end of Q1 but don't pin me down on it.

I know @Neotko has been feeling adventurous about modifying his print cores, and I believe he also installed a different nozzle. But it is important to know such modifications come at your own risk.

When you speak of a smaller nozzle, are you thinking of 0.25mm or even smaller?

If you don't mind sharing, I am curious of what you are making :)

Thank you for the info! That might work out just fine for me and I'm guessing .25mm would be sufficient.

I can't share the application but I am trying to print very small lattice structures. They printed to completion with the .4mm nozzle but there were holes and defects.

@Neotko any advice on the matter? What was your experience with changing the nozzle?

Precisely, but still excited to try the 0.8 for something soon.

3D Solex has a third party removable core (HardCore Pro) with changeable nozzles, as small as 0.1 mm  Here's a link

Haven't seen any reviews on yet though.. perhaps because its new

Edit: Funny I'm replying about the same thing a couple of days later. Sorry, I haven't seen my previous reply above.
