What Foamcube is good at
If you can describe it as a continuously moving straight line between two endpoints, a Foamcube can cut it from foam.
Tapered wings & airfoils
RC plane wings, hydrofoils, turbine blades, drone propeller cores. Different airfoil at root and tip, sweep, washout, taper — all in one pass.
Twisted geometry
Helical columns, propeller blanks, ergonomic grips, twisted ducts. Add the 5th axis to vary the rotation along Z.
Lofted shapes
Surfboard blanks, boat hull sections, packaging molds, architectural concept models. Shape A → Shape B over a defined length.
Ruled-surface architecture & sculpture
Hyperbolic surfaces, saddle forms, parametric panels for museum installs. Foamcube is a low-cost way to prototype ruled-surface geometry at human scale.
Variable cross-section ducts
Square-to-round transitions, speaker horns, HVAC intake prototypes. Both ends, any cross-section, one continuous cut.
Theatre props & brand activations
Big lightweight foam props for trade shows, theatre sets, retail displays. Paint, plaster, fibreglass over — the rough foam is just step 1.
STEAM education
Geometry made physical. Students design an airfoil in a browser, see it cut, hold the result. Stays under a school budget thanks to the DIY frame tier.
What it can not do
The wire is always straight, so Foamcube cannot make:
- Internal cavities
- Undercuts (without the 5th axis and indexed passes)
- Complex concave geometry inside a closed region
- Surfaces that require the wire to bend
For anything that fits the ruled-surface family, Foamcube is faster, cleaner and quieter than milling — and produces almost no waste.
