Surfce rationalization for Hot-wire and Hot-blade

Milling and 3D-printing are used in producing small prototypes of geometric objects, but for large projects these methods become extremely expensive. For large-scale production, like the tower, the HotWire and HotBlade technologies could instead produce building elements by cutting out expanded polystyrene (EPS) moulds for concrete casting.Our work focuses on approximating CAD model surfaces by ruled surfaces or elastica-swept surfaces.
