Posted · UltiMaker S7 ABS problem

Hi, I'm testing the new UltiMaker S7 and I'm having a problem with the ABS not sticking to the build plate. The UltiMaker website says that no glue needs to be applied to the PEI build plate , even when printing ABS. I tried a few variations with Dimafix, which also didn't help, and then with Magigoo Original, also no change. With Magigoo the printing took the longest, but after 2 hours the part still started to peel off. Of course in Cure I have Adhesion marked.

    Hey @Berec_admasys,


    Welcome to the Ultimaker Community 🎉
    Temperatures are super important for ABS so it might just be related to that. 🤔


    Do you have for us:
    A. The brand of ABS you are trying to print 
    B.  Do you have a project file for us? It contains the printer and settings we need for troubleshooting. To save a project file go to File -> Save project.

    I would start off by trying a higher build plate temperature.


    When I print with ABS I usually have the bed at 95-100°C, and I've noticed that it doesn't take much of a decrease in bed temp before the prints start to come off, at least from my experience. I do however print on glass bed with glue stick, but it might be worth a try in any case.

    Ah, I checked the suggested settings for ABS Extrafil Grey, but the temperature range is quite big. I agree with @43915  that you probably need to increase the temperature. 

    If you intend to print with this material a lot it's good to figure out the correct buildplate temperature. 

    This is the test that we do to learn the buildplate temperature.

    1. Print this file UMS7_buildplate_adhesion.3mf
    2. Check the following things

    1. The models' bottom side is flat
    2. There is no elephants foot.
    3. The model comes loose from the build plate after the bed cooled down.

    3. Increase the builplate temperature in case it doesn't stick and is not flat, decrease it if the elephant foot is too big. You can also alter the initial layer speed between 10-30 mm/s if the temperature changes are not helping. 



    Good luck!

    I used ABS from Ultimaker and raised the temperature on the build plate looks like it helped. Thank you for your help 🙂

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
