The team of the University of Tokyo developed a folding resin for a three-dimensional model of transformation in the event of heat.

CTOnews.com, August 11, according to the Nikkei Shimbun, a special lecturer at the University of Tokyo in Japan, Minghaiya, and Professor Guihiro Kawahara and others have developed a sheet that automatically changes into a three-dimensional shape when heated. By applying ink on both sides of the heat-shrinkable resin, control which parts shrink and which parts do not shrink. The team has also developed design software that can easily make 3D models.

Immersed in hot water of 70 degrees Celsius and 100 degrees Celsius, the exposed part of the uncoated ink will shrink and fold into shape. The sheet can make a three-dimensional structure like origami.

In addition, because it can be stored in a sheet state, the material has the advantage of improving transportation efficiency and is known as "can be made through an ordinary UV printer". The resin used on the sheet is also a general-purpose product, and the team believes that it can effectively control the cost.

As for specific uses, the University of Tokyo team said it will strive to improve durability for industrial uses such as cushioning materials, and is expected to use resins such as polyester for clothing.
