I have started printing with PETG so I can create objects that won't deform if I leave them in my car.

My first prints look good, but have strings of material coming off the print in places.

What should I try to prevent that?

I haven't had this problem with PLA.

I've had similar experiences switching from PLA to PETG, and haven't gotten it fully figured out yet.

From what I know so far, to reduce petg strings:

  • Increase retraction
  • Lower temperature

If you are using a printer that runs Marlin, you might consider upgrading to a version with Linear Advance. Once I started using Linear Advance, I reduced the stringing of PETG. Also I was able to reduce the retraction amount without reducing the quality of the prints.
