4D Printing Project

In a unique research collaboration between Stratasys’ Education, R&D departments and MIT’s Self-Assembly Lab, a new process is being developed, known as 4D Printing.

How it Works ? With Stratasys’ Connex technology, a

single print, with multi-material features, can transform from any 1D strand into 3D shape, 2D surface into 3D shape or more from one 3D shape into another.

The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to activate the self-assembly process.

With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials. (Imagine robotics-like behaviour without the reliance on complex electro-mechanical devices).

4D Printing: things making things 4d printing has nothing to do with a

fourth dimension. The big difference between 3d and 4d is that a 4d printer produces products which are able to adjust themselves according to their surroundings.

So the difference is after the product is printed. For example, when a product is printed and when it comes in contact with for example water is reshapes itself. The products will be able to reshape themselves in a precoded shape. The video shows how this looks like.

The 4-D printer creates a strand of multiple materials--and that strand becomes whatever you want it to.

Future Applications Although not commercially

available, self-assembly is just a beginning of a whole innovative world of manufacturing with minimum energy. As environmental, economic, human and other constraints continue to fluctuate, we will eventually need dynamic systems that can respond with ease and agility.

4D Printing is the first of its kind to offer this exciting capability. This is truly a radical shift in our understanding of structures, which have up to this point, remained static and rigid (think aerospace, automotive, building industries etc) and will soon be dynamic, adaptable and tunable for on-demand performance.

As a conclusion Of course we have a long, long, long

way to go before 4d printing is what I want it to be. Intelligent reshaping and flexible products. Maybe you can print a cube and when in contact with water it can change itself into a house. Remember: you have to be able to dream to look into the future.
