Thanks for the reply everyone!
@JoshK, very nice idea. I shall give it a try and see how it comes out! Thanks! For the record, it’s not a silencer for a gun, it’s the inside of tailpipe of a moped (though you were close with your guess, as this part does act partly as the silencer ;)). I’m going to design and print a full exhaust and see how well it’ll work compared to the original metal exhaust.
Yes, I am fully aware of heat issues and the spec sheet of the different resins. That still isn’t going to hold me back. Furthermore, I’m printing it in clear to see/show how the exhaust fumes act inside the exhaust itself. Of course it would be great if it would run and ride (at least once :P).
@Aaron_Silidker, as said to Josh, I’m will be printing in clear resin (V2). Epoxy is a definite contender for sealing. I’m trying to stick them together by dipping them in clear resin and curing them in a curing chamber. This definitely works, however I wonder how strong the bond is under pressure. Creating a joint which relieves part of the stess at that point is therefore essential (in my opinion). Eventually i’d like to mask the joints as much as I can so that it looks like it’s made out of 1 part. Of course there is a limit as i’m printing in clear resin.
@Steve_Thomas. Indeed another great idea. there might be an issue as the wall is only 2mm thick which doesn’t leave a lot of room for tapering, however, together with Josh’s idea, it’s a great contender. Thanks!
@Gary_Cairns. I did think of that, and I do have stl’s with all metric threads, however, as the wall is only 2mm thick, there is hardly any room to screw them together. Or I would have to design my own type of thread which uses only several microns as the screwing part. However, to ensure this will work, i’ll probably have to print it at .0025mm for the threads to work properly. As the parts are getting bigger and bigger (eventually taking up more than half of the build platform, and the full height of the build volume), this might cause easy print failures, as printing large parts at .0025mm is not a Form1+ favourite! ;).
I will definitely keep it in mind though, as it is absolutely a good way to join parts in a solid way. I would just need to find a way to do that on such a thin surface area.
