Suspension Bridges

Project STEM

In this project, you’ll be designing and making a suspension bridge model, before using it to learn about tension, compression and shear. View the project details below and start a free trial to PrintLab today!


Project Difficulty


This project is rated as intermediate and is suitable for all those who have moderate-strong skills in 3D design and 3D printing.

Project Length


The estimated project length is 2 hours, excluding any 3D printing time. This estimate includes designing and making 1 suspension bridge model. The project can be run in longer periods of time depending on the number of iterations you choose to make. We recommend breaking the project up into multiple sessions (e.g. 2 x 1 hour sessions), which will allow you to 3D print necessary objects between sessions.

Equipment Required


To participate in this project, you will require:

  • A laptop or computer with either Tinkercad or Fusion 360 software (both free for educational and personal use).
  • 1 x pair of scissors
  • 1 x ball of cotton string
  • 1 x reel of knitting thread
  • 1 x hot glue gun
  • 1 x roll of masking tape
  • 1 x A3 size base material e.g. 3mm foam board
