I’ve watched dozens of YT videos over the years where makers proclaim various adhesives as ‘just great’ for PLA and other filaments. People have different standards for what constitutes a good bond. Almost everyone says super glue is the answer. Some who say CA doesn’t work swear that Weld-On 16 will do it when nothing else will. I’ve tried both of those any many more and none of them work for me. If I can pull it apart without doing any real harm to either piece, it wasn’t bonded. I used to build acrylic (AKA Plexiglas) cabinets for hospitals. Weld-On 3 applied with a syringe would literally weld the pieces together. Within 10 minutes you couldn’t pull it apart without breaking one of them, but not at the weld.
There some value in a material that resists sticking to anything. Where would we be without Teflon? Add PLA to the list. At least-- that’s my story and I’m sticking to it (pun intended).
