3D Hotwire Cutting System

In the fi elds of model building, special packaging, decoration and show display, man-carrying airplanes up to wings for windfactories the many advantages of the Step Four system are appreciated. All current expanded and extruded polystyrene-foams can be cut. The PC processing guarantees absolute precision and reproduction without any programming knowledge.




This is what the Step Four Professional Cutting Software has to offer you create your cutting parameters using one of the available computer design or CAD programs, export the geometrical data in the form of an HPGL or DXF fi le and load it in the Step Four software. It is of course compatible with the Step Four standard wing cutting software.

The new developed turn table enables the creation of 3D-bodies. This useful accessory offers individual adjustable turning angles. The contours can be varied in any desired angle i.e. each angle can be arranged to a specifi ed contour. You also can turn the work piece during the cutting procedure.
