For foam modelers, a hot wire cnc foam cutter is a must-have tool. This machine uses a taut electrically heated wire to cut through expanded polystyrene foam such as the common home insulation, and it can create decent surface finishes with good dimensional accuracy.Resource :

The rotary tool also allows you to turn 2D CAD designs into G-code which is then fed into the machine, cutting the foam along the specified contours. If you’re building an airplane, for example, this means it can accurately cut out the tapered wings that are a signature of the design.

Foam Cutting Mastery: A Step-by-Step Guide with Hot Wire CNC Technology

A hot wire cnc foam cutter is especially useful for sculpting pink insulation foam, which holds detail better than EPS foam. So you can shape it into walls, roofs, and other terrain features for your model landscape. This is why the tool is so popular among hobby model train enthusiasts, wargamers, and others who use scale models of landscapes and battle scenes for tabletop encounters.

A hot wire cnc foam cutter typically has three interchangeable cutting tips to cover a variety of applications. Some have straight rods that can be inserted into the foam like a knife and can be used to cut both straight and curved lines in the material. Other models have bendable rods that act more like a router or traditional clay sculpting tool and which can be used to make negative space cuts into the foam, such as creating staircases, valleys, or other sloping surfaces in the material.
