Polymer based 2-D to 3-D Transformable Surfaces

Detailed Technology Description
Our technique is a method to design flat (2-D) sheets of polymercomposites which can be inflated to form a 3-D version of a real object or anobject designed in 3-D rendering software.

*Abstract

Technologiesusing stretchable materials are increasingly important. Yet, in general, we areunable to control how they stretch with much more sophistication than inflatingballoons. Inspired by nature, researchers at Cornell University have developeda technique allowing the calculated transformation of 2-D stretchable surfacesinto targeted 3-D shapes.

 

In ourproof-of-concept, we have shown that flat sheets of polymer can be inflated toform diverse 3-D shapes and textures, imitating plant shapes as well as naturalstone which blend with their background environment. These objects were able tobe cycled through over 100 inflation and deflation cycles.

 

 

 

Thistechnique is suitable for mimicking real objects as well as replicating objectsdesigned in 3-D rendering software, allowing for complex shapes to be producedfrom a variety of polymeric materials.

 

Unlike most inflatablestructures which are limited to positive curvature and symmetrical shapes, ourtechnique permits positive, negative and zero curvature areas as well asnon-symmetrical shapes.
