3D Printed Bridge

2.S998 Group Project - 3D Printed Bridge

Video: Testing the bridge to failure

For MIT course number 2.S998 - Additive Manufacturing, I worked with Josh Siegel, Isaac Ehrenberg, and Pranay Jain to design a bridge for the 3D printed bridge competition portion of the course. The object was to achieve the highest strength to weight ratio using a hobby grade 3D printer. See the competition prompt here. By avoiding the need for joints and designing the bridge such that the entirety of the load would be supported in tension, we managed to achieve the highest strength to weight ratio (6855 to 1). Weighing in at less than an ounce, it was able to support over 360 lbs. Take a look at our final report here.
