3D Printed Bridge

thingiverse

The bridge tipped the scales at a mere 10.5 grams yet successfully supported an impressive load of around 11.6 pounds, yielding a striking load-to-weight ratio of approximately 454. Meanwhile, the longer members were printed with a 70 percent infill density, while their shorter counterparts boasted a more modest 50 percent infill density. However, several problems arose due to the bridge's excessive height, rendering it notably weaker and more susceptible to breakage.
