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.
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:
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!
