A flyer from Tomorrowland advertising a prototyping technique.
The polymer becomes magnetically charged when hit with the lasers in the holographic projector. This spreads the polymer evenly and distributes it across the entire model.
People may make 3D models of their objects and plug them into their holographic projectors. After pouring the polymer in, they may make adjustments to their 3D model and have the polymer change simultaneously. The model is made solid by spraying hardener.
