In China printed origami using a conventional projector, and Power Point

Over the past few decades scientists have discovered many different polymers, different reacting to light. Some of them harden when exposed to light, while others disintegrate or shrink. Chinese physicists decided to use these properties for a kind of «3D printing» using a projector and computer with Power Point.

A Polymeric material that reacts to light, is placed in a special container, projecting her slide, thus illuminating it with different intensity, allowing the polymer to take the necessary form directly inside the tank. The duration of illumination and the brightness depends on the thickness of a specific area and its flexibility. Prepare certain slides, you can create the shape of almost any complexity.

Polymer, which was used by Chinese researchers, bends only at very small thickness, and therefore, it is impossible to create only a small origami whose size does not exceed a few centimeters.

However, this is a good Foundation for the future – anyone with a home projector and Power Point can do something like that, — says physicist Dinin Fan of the University of Beijing.

Now scientists continue to experiment with other types of polymers, trying to make something bigger and stronger.
