What kind of glue to use for Prusament PLA and PETG?  

RE: What kind of glue to use for Prusament PLA and PETG?

For a hard firm bond, such as you would get with a superglue type thing, I use Mike's Model 'n Craft Glue, available via Ebay or in person at most large train and hobby shows.  They specifically mention PLA and ABS, but not PET, although I assume it will stick to it as well.  I've met Mike and he's very personable, and I'm sure he would address PET if you phoned him.  Phone number on the web site https://www.drmikesglue.com/

For a more forgiving bond I use Aleene's The Ultimate Multi-Surface Adhesive, available at Michael's and I assume at most other craft stores.  This is what I use for model RR buildings and the like.

For PETG I use Gorilla gel super glue.  I prefer the gel as is stays put better.  The stuff is widely available but Home Depot happens to be the closest for me.

There are a lot of choices, but I've come to favor Starbond Cyanoacrylate. It comes in thick, medium and thin. The accelerator does not fog the plastic.  I started using it with tape as a  hold down on my CNC. It work just as great with my 3D Printing. Try it...

+2 on Starbond.  I recommend the thick CA Glue.  I also concur you need a bonder or accelerator.  I have had good success using this bonder with other CA glues.

Update.

Early this morning the magnet separated from my orange is-it-turning extruder indicator.  I re-glued it with Mike's glue and I can say very confidently that it sticks very well to PETg.
