Print text without blobs


Recommended Posts

Posted · Print text without blobs

Does anyone know which settings I can use to ensure that no additional blobs are printed in printed text?
In the example shown, sharp corners in the "W" and other letters are displayed with additional blobs. 

When I print prototypes in PLA, these do not bother me much. But here the whole thing is to be printed in TPU. These additional blobs are very noticeable and lead to extrusion problems due to additional retractions. 

In fact, the text would be even more covered with these blobs, but by switching off "Print thin walls" most of them are already filtered out here. 

I have already experimented with different settings and values but have not yet managed to get the text to print without extra spots.

    It looks like the sides of that part all lean towards the middle, and I assume that the text is cut straight in from the surface it's on? As in, the text cutout is tilted slightly toward the middle as well, and the top and bottom layers of the text are not completely parallel to the buildplate? A bit hard to describe what I mean in text, I hope you understand.


    If that is the case, the upper parts of smaller details in the letters will be isolated areas, or peaks, that are impossible to print without having a seam and retraction at that specific place. If the letters were cut completely straight relative to the buildplate you could get rid of those blobs by specifying where the Z-seam should be (as in anywhere else than on the letters, depending on your preferences).


    I could have a better look and test it out if you are able to share the model or a package file, it's a bit hard to see on the image exactly how the letters are modelled.

      • 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.
