The design is adapted to the possibilities that are created by 3D printing. The designs includes a lot of flowing elements that would not be possible with any other material or method. The whole bridge was split up in five elements because the size of the print area is limited. Four tension strands are put into place to pull the different elements together and allow more strength in the construction. Two of these strands are fixed on the two elements on the outside, with the element on the middle laying on top of them increasing the pull on the strands.

Printing line for the printer

Because the printing method is still in development we had to manually create the path for the printer to follow. To speed up that process we decided to use rhino7's inbuilt python scripting option. We ended up being able to create a short program that would automatically contour any object and connect the lines to create a path for the printer to follow.
Since the process of the printing in itself is very interesting we collected some pictures and a short video of the process. Since the modules have to connect to each other as good as possible the top five layers of the module, that came before the current module, are printed as a base.
