It is not possible (or let's play it safe; very very difficult) to remove the worn down parts in an Ultimaker 3 feeder without breaking anything else, and install a new set correctly. I'm sure one could find any component online, official or not official. But do make sure, if you want to go that route that you can actually install it and you don't end up with some parts you can not use. I think this is a fair 'warning'.

Hi @Carla_Birch, that you ordered them via NL does it mean you could not get them via your reseller?

As stated you can indeed insert AA and BB print cores in both Ultimaker 3 and Ultimaker S5. The only difference is the (soon available) Print core CC Red, this is only compatible with the Ultimaker S5. (Reason: The CC Print core is used for abrasive materials, and the Ultimaker 3 does not have a wear resistant feeder). I want to make a small addition to @Smithy's comment, I would not say that surface quality necessarily will get worse, you just have less resolution in X and Y. It's like using a fat marker for writing instead of a fineliner.

Hi @wraypa1, any updates on this? I'm curious if you could also reprint this model in (tough) PLA, see if the cooling properties of ABS have anything to do with it as well (or perhaps emphasize something else). Thanks!

My apologies for the confusion, if you follow this link you'll find the correct datasheet. I'll also correct the link in my original post to avoid future confusion.

Hi @lekezherka, did you manage to sort things out with your reseller?

And what did your latest test print look like? Was that it? ?

Nice idea! Have you ever considered printing them in something like Bronzefill? That may even oxidate when outside and give you a mode old/aging look. Example:

Did you plate this one with the new blend you had? (with the proper distilled water).

Those are the best issues, which fix themselves ? And get well soon buddy!

More profiles may be added in the future, but the print core CC Red will have the profiles for 0.15mm and 0.2mm ready. It may depend slightly on which material you plan on using, I believe XSTRAND only has 0.2mm from the start for example.

Another thing I wanted to add, was that it is also recommended to store XSTRAND dry and cool and potentially dry it before use. I like your idea about a dedicated print profile. Something like that has also been discussed a couple of times already, currently such a profile doesn't exist yet but it is definitely on the radar. I will let you know more when more information is available about this!

Hi @cloakfiend , I split your comments into a new topic so there is a higher chance someone might catch it and help ? (Plus, it didn't really contribute to the overhang topic anymore). Hope you don't mind!

I'm curious if anyone else who is involved with architecture has any questions for @Stefania Dinea too? Stefania is very experienced with 3D printing and architecture, so if you are on the verge of diving in or some areas are less clear than others, this is your moment, ask away! Specific questions, or more general about certain subjects. We can provide more content for you about it. ? I'm just going to tag a few people I know who are involved with architecture to make sure no one misses the opportunity. @Alex L , @Brendancavan , @Florisvh , @slspencer , @SarpSusuzer, @bigmodels , @DanielHolmSweden, @hghu? Thank you for your time!

Hi @P3D, thank you for your questions! I was out at the TCT show myself, hence my late response. Yes that is what I mean. The Ultimaker 3's feeder is not equipped to handle abrasive materials, the teeth will (quickly) wear off. How fast, depends on the material you decide to use. The Ultimaker S5 feeder (in particular the knurled sleeve) on the other hand is made of a hardened material and is also coated to make it even stronger. The dimensional accuracy is a synergy of the print profile used (like speed and temperature), the material (like shrinkage) and the printer itself (calibration). So it is hard to say by leaving two of the 3 influencers out of the equation how accurate it will be. I believe the added glass fibers make it less prone to shrinkage, which should make it more dimensionally accurate. I'll see if I can report back with something to make it more tangible. Let me know if you have any other questions ?

Not specifically as of right now. It depends on what material you use how fast your knurled wheel will wear off, so depending on your own findings you have to decide whether or not it's worth running that abrasive material through your Ultimaker 3. You have already been using these abrasive materials, do you detect any differences on your feeder? What we do know, at some point it will wear down and cause under extrusion. Since the feeders are press-fit, you can not simply replace the worn down knurled part, but you'll need to replace the entire feeder housing.

Through our alliance with larger material manufacturers we're happy to share the first filaments that become available to you through our Ultimaker ecosystem. One of those new materials is Novamid® ID1030 CF10, it's a carbon fiber filled grade PA6/66 filament. With a 10% carbon fiber reinforcement, it produces stronger, tougher and stiffer 3D printed parts. On a short notice the materials will be available to you through Ultimaker Cura. Novamid® ID1030 CF10 Data sheet. If you have any questions or experiences you want to share about this material, please share them below ?

Today we're at the TCT show in Birmingham UK, and we have the first CC Print core Red on display. If you are in the area, please come and check them out. The CC print core Red has wear-resistant ruby cone insert that protects the nozzle from highly abrasive composites like XSTRAND and DSM Novamid ID1030 CF10. The CC Print core red fits in both the Ultimaker 3 and Ultimaker S5, however if you want to use it to print abrasive materials the Ultimaker 3's feeder is not wear resistant enough to withstand these materials, and the knurled sleeve will wear off. The Ultimaker S5 feeder (knurled sleeve specifically) is enforced and coated, and therefore it is recommended to only use the CC Print core Red with the Ultimaker S5. It will be available to purchase in just a few weeks, but since it's on display now I wanted to share this news with you already. If you have any questions about it, feel free to post them below ?

Perhaps you already heard about the material alliance we are forming with several large material manufacturers, and I'm happy to tell you that it is starting to show off! XSTRAND is a high end 3D printing material, it's designed for functional prototyping, manufacturing aids, tooling and other industrial applications. It has stiff mechanical and thermal properties because it has a 30% glass-fiber reinforcement. Because of that, it is incredibly strong and has a rougher/textured surface. It is also highly abrasive. Because of that, it is only compatible with the new CC Print core Red (0.6 mm) and Ultimaker S5, because it has an abrasive feeder. If you have any questions about this material, feel free to ask us below! SDS-XSTRAND™ 3D GF30-PA6.pdf TDS-XSTRAND™-3D-GF30-PA6-.pdf

Hi @Padey, sorry to hear you seem to have some issues with your Ultimaker S5. Have you already visited the page and followed the instructions?

Hi @VigneshA, Happy to hear it is printing alright. Normal operating temperature of the stepper motor should be 50ºC. The Gyro is a rather complex print where all motors have to work hard so 70ºC is possible. But they should not get warmer than 80ºC. So I would say it is nothing to worry about.

Did you already get some models to test your mod on? ? Can you say a little bit more about what you're thinking off? I'm curious!

In case you missed it, Ultimaker Cura 3.5 | Beta is now available for download! You can read more about it here ?

Most likely there has never been an internet connection with your Ultimaker. If it can connect to the Internet it will set the date and time correctly. When it has adjusted, you don't need to keep it connected though, you can continue using your local network.

Op deze site kun je wat meer informatie vinden: https://ultimaker.com/en/resources/49799-material-compatibility Zoals je kan zien, zonder heated bed is PLA het beste materiaal om te gebruiken. Voor andere materialen, heb je een verwarmd bed nodig voor extra adhesion of om warping tegen te gaan, zoals bijv bij ABS. Met heated bed, zou je de volgende materialen kunnen proberen: Tough PLA, ABS, Nylon, CPE, CPE+ & PC. Voor sommige materialen, zoals ABS, zou je misschien willen overwegen om bijv de zijkanten ook dicht te maken om meer warmte binnen te houden en daarmee warming en delaminatie te minimaliseren.
