remove CA glue from PETG (self.3dprinting)

submitted 1 year ago by Imgonnatrythis to c/[email protected]

Heard I can use acetone for PLA, but not for PETG. Glued a joint and there is residue extruded and unfortunately it's a very shiny / translucent PETG. Any suggestions for cleaning up thin white residue stain from the cyanoacrylate?

Find the one that is the most "incompatible" with acrylic, and the other one that's the most compatible with PET.

CA Bloom is a pain to deal with. Loctite have a few recommendations on their website. https://www.loctiteproducts.com/en/know-how/fix-stuff/remove-super-glue.html#:~:text=For%20plastic%3A%20Lay%20a%20damp,substance%20break%20down%20the%20glue.

For future reference you can get low bloom CA glues for plastics that work much better.

Thanks, will give that a shot.

For future projects I'd personally recommend crystal clear epoxy. It takes a lot of time to set (40+ minutes) and even more to cure (24-48 hours), but the result is awesome.
