The Suspension Bridge of Construct

A customized 1:731 scale model of the Golden Gate Bridge, created as an educational civil engineering study. The project explores the working principles of suspension bridges, including load distribution, cable tension, tower support systems, and structural resilience, offering a hands-on understanding of large-scale bridge design.

Printing Guide

If you are printing this, you can use the assembled 3mf file and arrange and slice the components in your slicer according to your needs. In case you are using Bambu Lab A1, for convenience you can use the arrangements.3mf in your slicer Bambu Studio. Please note that, in this case the print shall be done in three plates, and for convenience, there is also a sliced file with supports.

Furthermore, whatever slicer you use, please make sure you properly assign the correct color to each slot of the AMS or multicolor system, like this:

If you don't have AMS or any multicolor system, you can rely on using spray paint for the colors which should be done before any assembly.

Assembly Guide (for Construct)

Assembling the project is pretty simple and straight forward. There are files for both the assembled file, which is the default file and the arrangements.3mf suitable for build plate of 256 mm3.

For each component, there are hubs and channels. You can just attach them together by pressing, and simply keep it as it is, if its tight, or you can use super glue.

For assembly, it is highly recommended to follow the Autodesk Fusion file thoroughly, and being able to connect the physically printed parts with the components on the .f3d. You should go through the hierarchy of the components, and follow that same hierarchy for the assembly. That being said, there are two main components: Deck and Towers.

The first thing you have to  place all the 7 deck trusses side by side.

Then you add in the joints and reinforce them by inserting the bars.

Then just place the Deck Tops into the positions.

For the Towers, attach the Lower Tower to the Foundation.

Then attach the Upper tower.

Now slide in the deck.

Congratulation, the model is assembled. It would be great if you can add galvanized iron/steel rope/wire and make it look like an actual bridge. The reason I removed the cables for the Construct is because it was too thin to print, and it could have failed.
