Evology Bridge Build Off

Welcome to the Evology Bridge Build Off—an engineering throwdown where your creativity meets our destructive testing.

Here’s the challenge: design a bridge using specific constraints, submit your file, and if your design makes the top five, we’ll 3D print it using FDM and test it to failure in glorious, slow-motion detail.

Yes, really. You build it, we break it. This is your chance to show what you’re made of (and what your designs are made of too).

HOW IT WORKS

1.

Design it.

Go crazy with it! Want to make a scale model of the Golden Gate Bridge? Be our guest. Got a crazy one off design you think can stand up to the competition? Lets see it. Just as long as your build fits within 16″ x 14″ x 1/2″, uses no more than a singular spool of material (92 cu. in.), and features no no mechanical fasteners.

2.

Submit it.

Upload your .STP file, include your design notes, and make sure you fill out your info at the form below.

Submission deadline: March 31st, 11:59pm.

3.

We Print + Destroy.

We’ll choose the top 5 submissions and bring them to life in our lab. Then we’ll crush them on camera. One design will reign supreme.

4.

You Vote.

As each design is tested, we’ll post the results on our socials. The community gets to vote on the People’s Choice—so make sure your bridge not only holds strong, but looks good doing it.

5.

Claim Your Bragging Rights.

Two winners will emerge: the Strength Champion and the People’s Choice Favorite. Both will win $500 in FREE ABS Printing.

Design Rules & Print Constraints

To make this fair and printable, all designs must follow these guidelines:

  • Must be submitted as a .STP file

  • All designs must span a total of 14” in length.

  • Must not consume more than 92 cubic inches of ABS material (Less than 20 cubic inches of support material).

  • Must fit within a 16×14 build plate with an overall height of no more than ½”

  • Attachment point will be THIS SHACKLE. Please ensure this is incorporated into your design.

  • Should be optimized for FDM 3D printing.

  • Cannot use mechanical hardware, all joints must be slip-joint style.

  • Design notes are required—tell us your inspiration or explain your approach

  • Finalists will be printed in ABS material on our Stratasys FDM printers.
