3D Bridge Competition

Student Activities

Bridge Competition Rules
The bridge must:

be made of only 3D printed ABS
span a minimum of 5 in.
be no more than 10 in. long
be no more than 3 in. wide
be no more than 3 in. tall
Weigh no more than 1 lb.
Accept a loading block 1.5 in. X 1.5 in.

The provided loading block must:

be centered horizontally across the 5 in. span.

pass completely through the bridge, parallel to the ground and normal to the long axis of the bridge design space.

vertical placement of the loading block does not matter given the bridge is supports all the weight.

The winner will be selected according to which bridge meets all requirements listed and hold the most weight without breaking.

Breaking will be identified through a bridge which may no longer support the test weight, or which deflects the loading block more than 1 in. from the original unloaded position.
