Dedicated print cores for different filament types?

Posted · Dedicated print cores for different filament types?

Is there any advantage to having dedicated print cores (just regular AA 0.4) for different filament types? I’m thinking mostly about PLA and TPU. I sometimes need to swap between the two multiple times in a week. Does the UMS5 take the different printing temps of each material into account when changing filament so as to fully/easily purge the other type? For example, if the higher print temp filament is removed and the lower print temp filament loaded will any of the higher temp filament residue left in the nozzle cause problems?

    Hi @kwakefield


    Your printer should indicate if the print-core is compatible with the material that you are planning to use. If I understand your question correctly you are wondering is there are any advantages (outside of compatibility) of using a dedicated print-core for a set of materials. I am not aware of any advantages here, it might depend on your personal preference. The printer will ensure that the core is properly prepared for the material that will be used. This includes purging the print-core to remove any material from the previous print-job, and like you said, the temperature of the previously used material is taken into consideration here.


    I hope that answers your questions, if not please feel free to ask more!


    Best regards,

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
