Our CNC hot wire table cuts polystyrene foam with a thin, taut metal wire heated to about 200°C. Heat from the wire vaporises the foam just before making contact. We vary heat and cutting speed to control results.

The wire follows a pre-set path through the foam via Computer Numerical Control (CNC) to produce profile lengths up to 8 feet long. We can also taper our cuts utilizing the independent axis option on our table.
