<p>If Carl's answer that cyanoacrylate glue works is accurate, I would suggest Loctite 420 or equivalent. It's diluted with solvents sufficiently to behave as a liquid rather than a gel, and in my experience on PLA it not only bonds the joint, but wicks between the extrusions and bonds walls/layers together much more strongly and waterproofs the part. As long as it bonds to PETG it should do the same for PETG.</p>

# What glues to use for PETG?

(Asked by: username_0 on 2020-02-05)

In analogy to: [What glues for bonding printed PLA to injection-molded plastic?](https://3dprinting.stackexchange.com/q/6723/4762), what are the best glues to use for PETG?

I mostly print in PETG and have occasional failed prints which I usually reprint. But what if I'd like to repair a print e.g. a split between layers or a part broken off?

Knowing that PETG is more "greasy" than PLA, what typical glues can you use to create a good bond; this question excludes using heat to (re-)bond.
