The basic construction of the machine consists of 2 mm plates made of stainless steel. Overlying are 1 mm stainless steel panels.
The icons and the lettering on the front and the logo on the back are lasered out of the stainless steel cover. A coloured and heat-resistant film can be applied to the 2 mm chassis plate underneath (as used by the car tuners).
This results in a nice 3D effect in connection with the chosen colour.
