3D Printed Truss Bridge

thingiverse

All the parts are printed with an infill of 35% as we believe this will make the bridge light and yet strong as possible. The individual parts are available for print, if you need to reprint only one specific member, however you can also just print the last two files with multiple members to print all the necessary members at once. The bridge weighs 25g (without the weight from the 11 metal joints used), held up to a weight of 37.2g making the load to weight ratio 1312. Here is a video of the bridge being tested:https://drive.google.com/a/students.mvcs.org/file/d/0Bw18wlz-RYnKY215eHVPM3Z6U3c/view?usp=sharing
