Hi !
I have a part to get printed with incredibly large overhangs (exceeding 7cm) therefore not even bridge nylon by taulman3d will do the job sufficiently, i need support structures!
Has anybody used other filaments as support for Nylon and with what material did you get the best results (do they fuse together or are they easy to seperate).
Also were you able to glue nylon and what glue did you use ? Otherwise i thought about constructing some screw mounts in the object, but thats not the solution i am looking for.

Hey there,
I haven’t printed Nylon with support structures made from other materials but I’d guess it should work well enough and should come away easily enough. There’s not much that actually sticks to Nylon so you can expect the support to do just that; Support the Nylon, but not actually stick to it. I’d give ABS a go to start, just because it comes easily to hand for me. If that doesn’t work, I’d try HIPS and finally PVA.
Far as actually gluing Nylon is concerned, same issue, really. Don’t even bother with Epoxy or Cyanoacrylate adhesives. They may stick for a short while but the bonds won’t last for long. I’d say your best bets would be Hot Glue and Nylon itself. Hot glue’s pretty much self-explanatory. With Nylon, what you want to do is put a short length of filament in a Dremel and weld the two parts together with friction. This actually works really well. Maybe best to do a combination of both. Make sure the surfaces you want to bond are really scuffed up, with sand paper. Use the hot glue to bond the surfaces and then weld the seams with the Dremel.
Hope this helps,
Cheers,

Thanks for all the information! Some guides in the internet recommended a welding knife to heat the surfaces that get stuck together, what do you think about this ?

Yeah. That could work. I guess you mean a soldering iron?? It’s probably a bit smelly and smoky though. If you have a Dremel, I’d definitely recommend welding with that. It’s a remarkably effective technique.

I also thought they mean a soldering iron, but maybe a soldering knife is just like that but with a larger plate instead of a tip, then it would be possible to heat the whole surface easier.
How exactly do i weld the parts together with a dremel ? If i understood you correctly you mean that i should put filament around the dremel head and rub this on the surface that has to be glued ? or how should i get the friction on both parts that have to be glued ?
Maybe you have any link or video as reference
Its called friction welding.
