Acrylic hot bending techniques

Acrylic is an easy to bend material with reasonably low amounts of heat. Two main techniques can be used: hot gun and hot wire.

An example of a final product:

Doing this in fusion360

Fusion360 comes with a nice module for sheet bending. It’s called sheet metal. You can find a tutorial here.
