Brooklyn Bridge 3d printed

[rainerstoll]

Hello, I am looking to have a G scale model of the Brooklyn Bridge (New York) 3D printed. I’d appreciate any pointers or recommendations to folks who can tackle a project like this. Thank you

Hope you have a lot of room will be big, oh and plenty of cash as it will cost mega bucks to be designed and printed commercially. 1595 feet long 127 feet above water, 1:29 scale that is roughly 55 feet long by 4.3 feet high.

Thanks yeah that is big.

Thanks yeah that is big.

I actually made it to be bigger than that. The length, including approaches, is 6,016 feet, which at 13.5mm to the foot is 81.216 metres or 266.48 feet. The central span, alone, is1,595.5 feet, which comes out at 21.539 meters or 70.67 feet. Not sure there is enough 3D filament in the world to build that.

Would any printing be strong enough to cope?

I went for just the published bridge size, indeed if you count everything else one would be into serious planning issues in UK, USA likely to have similar planning requirements.z gauge more realistic to get it done, even then be quite big thinking Z model of Forth Bridge.

You would not want this 3D printed, especially if it is to go outside..
It will twist, warp and change shape horrendously. - You would be disappointed, and have wasted a considerable amount of money.

Some will disagree with me, but my real-world experience of 3D printed items, is most are not stable. *

*Different materials will make a difference, but you are getting into material sciences, and need expert advice on them.

with a good level of detail.... you said G Gauge??

I would suggest laser cut steel for the main structure, with added rivet detail, hand rails etc manufactured using model engineering techniques - brass turned on a lathe.

Totally agree that 3D printing is not the right technique k a large structure.

As a C&O fan living nearby in Kentucky as a youth, the Limeville (the Ohio folks called it Sciotoville) Bridge was a spectacular sight every time we passed it. This project was incredible!
