3D CNC machining of Styrofoam / EPS foam

3D milling Styrofoam / EPS: car body

Photos and videos relating to 3D CNC processing cellular materials, in the first example of styrofoam milling with The CNC portal milling machine / cutter RaptorX SL

con_infoDue to the 3-fold in height positionable table support struts * You always have the choice to work, sheet materials with high stability or high 3D bodies.

In this example with the 3D CNC milling machine RaptorX SL we are milling with a very special Styrofoam cutter (diameter 20mm and length 150mm) made of steel. The depth infeed when roughing was selected here with 140mm, the distance between the milling paths is 5mm, when finishing at 1.5mm. The toolpaths were generated by the software ConstruCAM 3D. The feed speed is 100mm per second, 6 meters per minute. The complete form with approximately 600 x 450 x 140mm size was completed in just 15 minutes. These materials could be finished directly with small stepover, to save time, without pre-milling the workpiece.

Using the selected router with high feed rates, regarding the material, we received a clean and rather smooth surface, which already comes very close to a hot wire cutting. There are special paints or roll.- paint.- and sprayable two-component coatings for the surface treatment  of polystyrene available,these materials even in high-gloss can be weather-proof!

Thus, XPS / Styrodur is the ideal material for exhibition stand construction, 3D mold construction / large mold construction. Also, the CNC milling machine RaptorX SL is suitable for 3D processing in wood, metal and even stone ! Corresponding videos can be found on additional websites.


For engraving work in larger dimensions RaptorX SL the CNC portal milling machine / CNC engraving machine is also the right partner for your work.

By creating a stable construction made of thick steel pipes and the large-sized drive motors, it is even able to work stone, marble, slate and granite.

* Table support struts are available as an option
