My print result has a lot of threads

[cmitran 1]

Hello,

 

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.
