ozzyo Posted January 13, 2022 Share Posted January 13, 2022 (edited) As the title says what is the best glue for sticking down 3D printed chairs to ply sleepers. For the plain track I'm using MEK (99.9% Butanone), but for the printed chairs I don't think that it will work. The printed chairs will be for the interesting chairs in the point work on the front of Lochmaben, two of the points will get a lot of use as these are the cross over, so we cannot afford the chairs to come loose. TIA OzzyO. Edited January 13, 2022 by ozzyo Link to post Share on other sites More sharing options...
RMweb Gold ikcdab Posted January 13, 2022 RMweb Gold Share Posted January 13, 2022 I have made a lot of track using c&l chairs on ply sleepers and butanone worked very well. Is it that the 3d filament is not softened by butanone? If not, then you just need to find the right solvent. Either that or use a filament that is softened by butanone.

I'm certainly no expert, but I'd say the answer to that question will be wholly dependent on 2 factors: a) what method of 3D printing was used to print the chairs, and b) what material were they printed from?

RMweb Premium eldavo Posted January 13, 2022 RMweb Premium Share Posted January 13, 2022 (edited) At a guess super glue (cyanoacrylate) is probably your best get. The most common materials used in 3D printing are PLA, for filament extruded printers, and photoreactive resin. Neither of these have commonly available solvents that you can use as an adhesive.

hayfield Posted January 13, 2022 Share Posted January 13, 2022 Ozzyo I bought some Loctite 60 second all purpose glue as I wanted to stick plastic timbers and sleepers to my trackbed. Its a cyanoacrylate glue which is not an instant bond, as its repositionable for 60 seconds, though on non porous surfaces it seems to take longer. I am also using it on a laser cut building kit and plastic sheet as well as card and wood. It states its extra strong and designed for larger surfaces. It comes in a 20g tube so goes a long way. I have done quite a lot of work with it and found its excellent 1 1 Link to post Share on other sites More sharing options...

OzzyO. Thanks. It's a "material jetting" printer which is a bit like an inkjet printer. More info here including a data sheet for the actual material. https://www.shapeways.com/materials/fine-detail-plastic That stuff can be difficult to glue and the parts might have a wax residue on them from the printing process. As it's a portable exhibition layout you need a really secure connection between the chairs and the timbers particularly if the chairs are holding the rail in place. Best to do some serious testing before yet get too far with construction. The adhesive John (Hayfield) uses might be fine or you might have to go to a UV cured adhesive - bit like the stuff dentists use. BTW that plastic is not suitable for use outdoors as it degrades with UV light which is why I asked. But you won't have that problem. Just a thought but it might help to apply some sort of sealer to the plywood first. Andy Link to post Share on other sites More sharing options...
