bodmin65 Posted February 16, 2020 Author Share Posted February 16, 2020 These two photos might explain it a bit better. These are for n gauge code 80 flexible, but could easily be adapted to oo gauge. Link to post Share on other sites More sharing options...
RMweb Gold 55020 Posted February 16, 2020 RMweb Gold Share Posted February 16, 2020 I don't understand why it would quieten running. 3D printed materials are solid, so there's no sound deadening qualities. I'm sure I must have misunderstood? Steve 1 Link to post Share on other sites More sharing options...
Mike Buckner Posted February 16, 2020 Share Posted February 16, 2020 Interesting idea. Among the potential applications: A bespoke-radius harness for flextrack A bespoke transition curve Link to post Share on other sites More sharing options...
bodmin65 Posted February 17, 2020 Author Share Posted February 17, 2020 As the infill would only be 5% I'm thinking it would be mostly air. So wouldn't that give you quieter running? Tbh I've not made enough of it for an entire length of flexible track to test it out yet. But how would you successfully measure the difference anyway? Maybe by recording a video perhaps?

regme Posted February 18, 2020 Share Posted February 18, 2020 Was that resin or filament you used? I'll assume resin for this so I'd be interested in much resin was used to print one section? What's the length of the part? How big is your layout? Then you'll know how many bottles of resin you will have to buy to finish your layout (that's if you don't get any failed prints) and is that cheaper than buying cork? Also, your shoulder is too high, maybe hold it in place between the sleepers, that way when you put ballast over it, it won't be too high. Link to post Share on other sites More sharing options...

Resin tends not to produce such a rough finish. Even if it is PLA (or similar), it ain't going to be cheap. Steve Link to post Share on other sites More sharing options...
etendam Posted February 18, 2020 Share Posted February 18, 2020 I would go for very soft materials. The sound of the running train will also just increase. Ed Link to post Share on other sites More sharing options...
