As many people have never worked with thermoplastics, it can be a bit intimidating to figure out how you could use these products. So here we have some examples to show the basics of using Worbla.
To fold, crease and cut:
You can also mark the cutting line using a ruler and pencil instead of folding first.
Worbla responds to heat and becomes very flexible. Here we show the initial stiffness of the thermoplastic, and how it changes after a few seconds of heating with a heat gun.
Once the piece cools down and hardens, we can turn it around and heat it again to flatten it out.
A regular hair dryer can activate Worbla too; it just takes a little longer to heat the Worbla.
Here we see how Worbla can stretch to take a convex shape. While hot, it can be molded over objects or pressed into a concave mold.
Once it cools, it hardens and keeps the shape:
Folding and layering:
The material sticks to itself when hot, which is very useful if a thicker and stronger piece is needed: Just heat and press a few layers together to create a stronger sheet. This is recommended if you’ll be stretching the Worbla over a larger domed surface, as stretching a lot will thin the Worbla.
Here we see how easy is to emboss Worbla once it’s hot:
We hope these notes are useful. We’ll be trying new techniques soon, so stay tuned!
