Introduction: Cardboard Bridge

This is a bridge created from 3D printing, as well as cardboard. We chose this because we wanted to go with a design based around a piece of architecture. Therefore, we decided on a Parker Bridge.

Supplies

You will need:


  1. Cardboard
  2. 3D Printer
  3. Autodesk Inventor
  4. Scissors
  5. 3D Printer
  6. Hot Glue Gun
  7. Pencil
  8. Makerbot Print App

Step 1: Designing

First, sketch out your bridge on Autodesk Inventor similar to the first picture. Once done, extrude the inner areas and bottom. You will then want to sketch and extrude a "roof" over the bridge before drawing the pattern you want above it and cutting it once again.

Step 2: Printing

Export the Bridge file as a .stl file and put it into the Makerbot Printer App. From there, select the printer you will be using and export it into a USB drive. Plug the USB drive into your desired printer and print!

Step 3: Cutting Cardboard

While waiting for the printer to finish printing, grab a sheet of cardboard. Cut it into small squares.

Step 4: Hot Glue the Pieces

Use Hot Glue to glue the small squares into groups of 3. This will be your support beam for the bridge.

Step 5: Assemble Onto Bridge

Use the Hot Glue to glue the cardboard support beams onto your bridge. Ensure there is one for each side of the bridge.

Step 6: Finished Product

Congratulations! You have now finished your project and may now showcase it proudly.
