This instructables goes over how to create 3D word's with cardboard, and with some clever lighting you can make it so that the shadow cast creates a cool effect.
What you will need
- Laser cutter
- A 3D modeling program
- Autodesk 123 Make
- Laser software of your choice
- Cardboard sheets
- Light source (preferably with a narrow beam or light)
Step 1: Starting Your Part
You will need to open up your favorite 3D editing program, I used Autodesk Inventor. Start off by making a long block then start writing some text on one of the faces align towards the top, and extrude.
The letters should look like as if they are almost resting on top of the block but still connected.
Note: If you use all Capital letters you will not have to deal with any floating parts to any letters like the dot for the lower case i.
Step 2: Making It Look Cool
Top view above your peace try to make a wave like pattern to extrude out of the part. You can use different axes to make more intricate patterns, there is no science to it but I noticed extruding curved parts out are better than sharp angles.
Note: Just make sure it will be able to still hold itself together later when sliced.
Step 3: Exporting Your Part and Slicing It Up
You will need to export your part into an .STL, after that import it into Autodesk 123D Make. In this program you can slice your part up and it even has instructions for putting your cut parts together.
You will after slicing your part export into a .dxm, use a laser to cut the parts from cardboard.
Assemble all your slices one on top of the other with some glue in-between slices and once dry your part is done.
Step 4: Experiment With Lighting
When you just get in a dark room with a flashlight, your part and a with just a little experimenting you will find some cool ways to display your text.
If you noticed there is a secret message :) you can put multiple messages in one part using two sources of light and having your text on two axes.
Have fun makers.
