    New print core not recognized in S5

    in UltiMaker 3D printers

    Posted

    Hi Andy, 

     

    Thanks, I am happy to hear so. FBRC8, our US partner, always does a great job and I trust you are in good hands with them. Although we do our best to prevent any malfunctioning with our equipment, you can't rule everything out and in that case it is important to have a support network you can rely on. 

     

    Let us know if you have any further questions or how it plays out with your print core!

    How to 3D print with metal

    in Materials & profiles

    Posted

     

    3D printing with metal is fascinating and has an appeal to many people. It can produce impressive results and handle some applications that are just out of reach for the usual (reinforced) plastics that we usually use. So how could you go about it?

     

    3D printing is a broad term, well beyond FFF we're all familiar with. And many technologies can process metals (often with a hefty price tag) Below we briefly describe the most commonly used technologies:

     

    Direct Metal Laser Sintering (DMLS)
    DMLS uses a laser to melt and fuse metal powder. This is called sintering. It uses alloys (rather than a single type of metal), which are made up of metals with different melting points. They fuse together as the temperature rises. 

     

    Bound Metal Disposition (BMD)
    BMD extrudes, similar as FFF. It requires metal bound in rods of polymer or sacrificial wax rather than powder. 

     

    Selective Laser Melting (SLM).
    Much like DMLS, SLM also uses a laser. But in contrary to DMLS, SLM only requires a single metal instead of alloy. 

     

    Others
    There is also Electron Beam Melting (EBM) and Ultrasonic Additive Manufacturing (UAM) but they’re less commonly used. 

     

    And although not 3D printing, there are also other means of manufacturing that are commonly used to process metals. 

     

    Investment casting. 
    Investment casting uses a mold (which can be 3D printed), in which the molten metal is poured. Investment casting allows for a good level of detail and is quite popular. As an example, a good success story that does investment casting is Sylatech

     

    CNC machining.
    The technologies above are quite costly, some even out of reach of most SMEs. CNC is much more affordable than some of the technologies mentioned above and can also process metals. It is not Additive manufacturing, instead it is subtractive. While it is more affordable, it also has some limitations to being less effective for parts that require geometric complexity.

     

    Now we wouldn’t be writing this if we also didn’t have something to contribute to this topic. But it may not be for everyone, your hardware needs to be up to the task! 

     

    Hardware requirements. 

    • Build-plate: You need a heated bed which can reach between 45ºC and 60ºC. An enclosure is not necessary. 
    • Build-plate surface: The surface may require tape (oh hello old friend), PEI and a glue stick. 
    • Extruder: A CC Core is required, and temperatures between 190ºC and 220ºC. 
    • Fan: A cooling fan is a necessity. 

     

    So, which materials do we have in the marketplace? 

     

    BASF Ultrafuse 316L
    Talking about metal 3D printing, there is only one real champion in our marketplace. And that is BASF Ultrafuse 316L. BASF Ultrafuse 316L is a metal-polymer composite, containing 80% stainless steel and 20% polymer. Ultrafuse 316L has the following properties:
    •    Produces stainless-steel type 316L parts
    •    Tensile strength of 561 MPa
    •    Yield strength of 251 MPa
    •    Vickers hardness of 128 HV10
    •    Elongation at break of 53%
     After your print is completed on your Ultimaker it needs to be post processed, meaning debinding and sintering.

    There are also materials in our marketplace which are not metals but have some similar properties in case you need just low-friction or high tensile strength:

     

    • DSM Arnitel ID 2060 HT and Clariant PA6/66GF 20 FR. Both filaments are thermoplastic and able to withstand very high temperatures, just like a metal. They also offer good wear resistance
       
    • Arkema FluorX and DuPont Zytel 3D12G30FL BK309. These materials make excellent substitutes for stainless steel, as they offer a high level of corrosion resistance. Chemicals such as solvents, automotive fluids, and cleaning agents don’t result in any deterioration
       
    • Igus Iglidur 180. This filament is self-lubricating, which makes it highly resistant to wear and tear. It’s suitable for creating parts that are traditionally metal, such as bearings, toothed wheels, piston rings, and gears
       
    • XSTRAND GF30-PA6. This filament contains 30% glass fiber, which gives it good chemical resistance, high tensile strength, and a good operational temperature. It is well-suited for printing jigs and fixtures

    Thanks. No, it is 100% not an estep calibration. In all my years I've never seen that as the culprit. It could be a form of over extrusion, like I mentioned with the excessive pressure that finally gets released on the outer wall. 

     

    Luckily the S5 (and Cura) has many options to configure, so we just need to figure out what settings and/or profile works best for what you're trying to achieve. The more experience you have with 3D printing, Cura and the S5 the sooner you will be able to identify that even before a print starts. 

    Ultimaker Cura 4.7 is available!

    in UltiMaker Cura

    Posted

    Today we celebrate the launch of Ultimaker Cura 4.7 stable. After yet another Beta test period where our amazing community helped us test, we feel comfortable to move forward. So, what do we have in store for you:

     

    With this launch we are also trying something new. We've created a short video where we inform you about a range of new features that are in Ultimaker Cura 4.7. What do you think? Is it useful for you? The usual description and highlights of Ultimaker Cura 4.7 you can find underneath.

     

     

    Improving your workflow
    Adding a Cloud printer to Ultimaker Cura became much easier. Where before you had to add each individual printer, Cura adds all printers you have in the Digital factory when you sign in with your Ultimaker account. If you don’t log in, account synchronization can be triggered later via the “Add a Cloud printer button.” A reboot is not needed to install printers. 

     

    Improved search
    The wide range of available settings can be a blessing when you want to fully optimize and configure your print strategy. But sometimes it can also be overwhelming. “What was that one setting called again I used the other day? It had something to do with ...” With this improved search you can search for what a feature does, instead of what it is called.  Practically this means you can now search for keywords that match the description of a feature. 

     

    Model error detection. 
    When you upload a model which is not a manifold or contains errors Cura will present you with a pop-up warning. You can go back to your CAD software to correct it and retry slicing it in Cura, saving you the time and frustration of discovering the error during mid-print. Thanks to @ahoeben smartavionics, and @bagel-orb for their contributions to this feature

     

    Tree-support improvements.

    Together with moving the tree support out of the Experimental category and into the support type dropdown, we also fixed multiple reported issues where the support branches would interfere with the model, or the support bottom distance was too small, or printing in the vase mode. Thanks everyone who helped testing! 

     

    Rotation widgets. 

    @ahoeben has contributed code that adds three pairs of arrow widgets to the Rotate tool handle, enabling you to rotate objects by exactly 90 degrees.   

     

    Performance improvements with multiple 3D models. 

    In previous versions many objects on a build plate could cause Ultimaker Cura's performance and response to be slow. We have made some code optimizations to increase responsiveness in such cases.  

     

    Thank you all that helped with testing Ultimaker Cura 4.7 Beta, and realize this stable version. Your efforts mean a lot to us! 

     

    That is not all! More features and bug fixes can be found via this link. 

    Ready to give it a go? Download Ultimaker Cura 4.7 now.

    Direct link to dmg and exe.

     

    Let us know below what you think! Have a great day!

    Layer Shifts and Extrusion Problems (S5 Pro 0.8 AA)

    Hi @TrueNorth, thank you for your file and patience. I've discussed it with my colleagues and we would recommend to enable outer before inner walls  in Cura, and disable coasting. Since you print so many walls and such high density it is likely you build up a lot of pressure in the print cores. Currently, with the outer walls printed last, it is likely that is where this excessive pressure is going. Reverting the order, you will still have the pressure, but it will be 'released' on the inside of your print. 

     

    Oh, and you mention in your last post it 'otherwise should be a stock 0.4 profile'. You print with a 0.8mm nozzle, and have layers of 0.2mm. Is this a typo or did something not match your profile in the curaproject file?

     

    Let us know if this helps! 

    calibration sheet

    Posted

    Dag Eric, 

     

    Welkom bij de Ultimaker community, en gefeliciteerd met je Ultimaker S5! Welke calibration bedoel je, voor manual leveling of voor X en Y calibratie? Voor manual leveling kun je een standaard A4 papier gebruiken eventueel. 

     

    Voor XY calibratie kun je op deze pagina het ontwerp dowloaden. Die zou je dan nog wel even moeten printen zelf. 

     

    Succes!

    ER34 At End of Spool - More $$$ Lost

    Any advice on how to recover from this? 

    Recovering from an ER34? This is I believe only possible via a reboot. 

    While I would happily continue to try and help you, I would also like to ask if you would want to create a ticket in our support system via this link, that way there are no blind spots in our data and monitoring the frequencies of certain error messages. ER34 is a good one to keep an eye on. 

     

    Can you still unload it from the material station? While it may not be visible anymore, the feeder could/should still have a grip on it. 

    39 minutes ago, CTotten said:

    does the material change routine use material specific temperature profiles, or does it use a generic "one-size-fits-all"?

    It uses material specific temperatures. 

     

    40 minutes ago, CTotten said:

    It just seems odd to me that I have had SO MANY problems with mid-print material changes since the 5.7.2 firmware update, but I have had NO issues with the end of print routine.

    That is odd indeed, and hopefully we'll get to the bottom of it together. As I mentioned before, please also write a support ticket if you haven't done so already. 

    How do I load a new material from Cura into a UM3?

    When you test it, make sure the material is compatible with the UM3.

    I just tried downloading and installing two materials from the marketplace (MatterHackers NylonX and Proto-Pasta Copper)

     

    Looking at the marketplace profiles, both of these materials are not compatible with the Ultimaker 3. They do list the UltimakerS3 though. @threepoint, your profile says you have an Ultimaker 3. Is that correct?

    Hi @pizemakerstation, I am not sure which crack you are referring too but I will recommend to look into two features of Cura that would probably help. Apologies if I read your photos incorrectly. I would recommend to look into the Z-seam feature, and set it to random. The Z-seam forms when the print moves to the next layer and a small blob can form where the print head is while the bed moves down. Cura can hide this in a corner, but it can also scatter it randomly so it is less visual. 

     

    For the 'scar' on the inside surface I would suggest to look into the comb feature, and set it to 'Not in skin' if it is not already (I think it isn't). 

     

    Thanks, looking forward hearing from you if this made a difference!

    ER34 At End of Spool - More $$$ Lost

    in UltiMaker 3D printers

    Hi @CTotten Thanks again for your amazingly detailed post and research. I do believe that the break temp for PLA is 60 and CPE is 75 because it is suppose to 'break/snap'. It is being pulled back a little bit so a small tip forms, then it cools down, and then it pulls back quickly to generate the snapping sound you hear. Regardless, I will pass this feedback along to the material team to collect their thoughts on CPE specifically since you have had more issues with it and report back with you. 
    They do test all profiles and materials in real life, we don't just deduct 15ºC from glass temperature, but feedback is always crucial.

     

    About the ER34, I doubt this is caused by a cold pull. It is peculiar the print head is sitting in that position when ER34 occurred tho. Can you check the pcb of both print cores on the back, if they are still intact? Perhaps also in the print head? Sharing a photo could help. 

     

    Could you also share the log of your print when it failed with the ER34?  

     

    Thank you! 

    Material Station Bypass Option?

    in UltiMaker 3D printers

    Posted

    Hi @bvsengineering, do you mean like mounting the material on the back of the Ultimaker S5? That is possible if you install the regular spoolholder. It would require you to disconnect the Material Station though, which might be a hassle. 

     

    As a workaround, you could also select a generic material of a material that matches or is very similar to the material you are trying to use. Because this is not exactly the same, results may vary and I would recommend to monitor the start of the print and occasionally check in on your print the first time, to ensure all goes well.

    Hi DD, 

     

    thank you for your message. Does nothing respond anymore, or are you trying to hit 'submit' and it doesn't respond? What I have noticed it that when the submit button is exactly next to the chatbot, there is a small area reserved by the chatbot that is non-clickable for when the chat opens. If this is the case, perhaps you can try to scroll up a little bit until it is above the 'How can we help' and it should work. Could this be it?

     

    The Ultimaker forum is part of our ecosystem and since we introduced Ultimaker accounts they have been synced. Which means if you create an Ultimaker account in Cura you also gain access to the community with your account.
