    Has anyone tried gluing two PETG parts together? I have read online that it can be difficult. They mention Weldon #3 or Weldon #16, but was wondering if anyone here had experience? Maybe just loctite super glue or something?

    I haven't tried gluing PETG yet, though I probably will some day. When that day comes, I'll try Gorilla Glue or one of its equivalents (i.e. a moisture-curing polyurethane). If that doesn't work, I'll try epoxy next.

    I can tell you that PETG seems immune to acetone, which suggests that cements like Weld-On, which partly dissolve the components to be joined, won't work.

    Well just because acetone doesn't work, doesn't mean another chemical won't... Weldon isn't acetone I don't believe..

    I just found this

    "3™: Water thin, non-flammable, very fast-setting solvent cement for bonding acrylic. It will also bond with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), PETG (polyethylene terephthalate glycol) and polycarbonate to themselves. It will not bond to cross linked acrylics."

    I did say "suggests it won't work." If Weld-On says it will, then it probably will. Might give it a try myself, when I feel the need.

    :cool: Please let us know how it works. Gorilla Glue is great stuff, but the foaming can be a real pain in the wazoo.

    Not really aligned to the question of how to connect PETG, but I wanted to share my experience of putting a PETG printed item through the dishwasher. It survived completely unscathed!.

    Holy crap! At that price, Araldite should be able to bond Teflon to Teflon.

    I discovered this paint stripper by coincidence, a couple of days ago. It works amazingly well with PETG, creating a super strong bond (weld) withing a few minutes. I tried to break it apart with all my strength, but couldn't. The one I use is a semi-liquid gel, which is great because it leaves plenty of time to apply it with precision, and won't crawl all over your print like acetone does to ABS. It stays in place. Unfortunately, this particular product is only sold in Canada, but I know you can find an equivalent in other countries. The active ingredient is methylene chloride (Dichloromethane). It is very toxic, but I only use it briefly, in tiny quantity. http://www.superremover.com/products/super-remover

    Dichloromethane has been banned in paint strippers in Europe since 2009.
    If you have any nitromors older than that it’ll still have it in.
