Like a giant slide projector - A mobile projection screen for intricate work in the automotive sector enables close inspection of 1:1 scale models

Thomas Kleefeld Metallbau, based in Krefeld, Germany, has designed and built a mobile back projection room to enable a customer in the automotive sector to work with projections of 3D computer models in 1:1 scale. The room, which has been dubbed VisWall and ensures both stability and flexibility, is made from components in the MB Building Kit System from item Industrietechnik GmbH. Projecting images or films in their original size helps observers to get a clear impression of details and a realistic overall impression of the project. The entire room can be moved on rollers and made smaller for transportation by slotting the section containing the projector into the rest of the projection space.

The core element of the system is a 5-metre long and 2-metre high specially coated glass panel that serves as the projection screen. The projection beam is guided onto the screen via a tilted mirror that can be adjusted along three axes. The alignment and spacing of the projector, mirror and projection surface must be exactly right to ensure the image is perfect.

The projection surface, which weighs in at 250 kg, must not sag by more than 1 mm in order to ensure optimum image transfer. This condition was met by suspending the panel on an item MB Profile 240 x 40 with eleven T-Slot Sliders. The frame of the room sits on Heavy-Duty Castors 8 from the MB Building Kit System and can be reduced in depth from 3.72 m to 2.2 m and moved freely.
