My print result has a lot of threads

Posted · My print result has a lot of threads



I am a beginner in 3D printing and I have a question.

My 3D print result has a lot of threads, see attached image.

I have used PETG 1.75 of 0.2 and I don't know what's the cause of this result.


Could you please advise?

Thank you,Cristian

1) Try PLA - it's an amazing material and won't string so much.  It's just as strong as PETG and does well indoors or outdoors but gets soft at a lower temp (around 52C or 130F) which is enough to kill humans but is sometimes experienced in a closed car on a hot day.  So that's the one thing where PETG is better - it can withstand a little higher temperatures.


2) I also get much more stringing of my PETG but not that bad.  I'm not sure why you get quite that much.  Did you play with retraction?  You want just a little bit of retraction.  You can check if those moves that strung included retraction or not as there are two different shades of blue when you look at it in PREVIEW mode.


3) I have been told that PETG strings more if it gets "wet".  You could try drying it on a heated bed with a towel over it with the bed set to 60C for 4 hours.  I have never dried my PETG (nor PLA) but you must keep PVA and Nylon very dry.  PETG I don't care about and it does string but not as much as you show here.  Nylon needs to be dried even if it was at 50% humidity on the back of my printer for 1 day.

      • 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.
