Allan Bennett Posted February 21 Share Posted February 21 I've just managed to remove a damaged wingtip cleanly from a 3D-printed model using cyano debonder. It seems to me that the gooey residue is hardening with time, so it seems like I'll be able to glue in the replacement tip by tomorrow. Is that right, or do I need to somehow remove or deactivate all traces of the de-bonder before regluing? I think I've removed it all by scraping, sanding, and wiping, but don't know if there's any residual absorbed in the structure. Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted February 21 Share Posted February 21 If youve removed all the visible residue and lightly wiped over with a degreaser/ thiners then it should be fine. Debonder works by softening the cyano and will evaporate away . The closer fit of the joint the stronger it will be. Good luck with repair. 2 Quote Link to comment Share on other sites More sharing options...
Allan Bennett Posted February 22 Author Share Posted February 22 Job done! The debonder does make quite a sticky mess. Some of the gunge I scraped off was the colour of the lightweight PLA that was used to print the model, but I don't think it's permanently affected it. After scraping the gunge then wiping with surgical spirit I let it dry off before using cyano to attach the replacement wingtip. All looks good.
