![]() For example, 3D printing a miniature character and leaving it alone overnight will result in exactly the same character the next day, because the PLA filament or other filament will not change overnight. To explain: adding time to an object that cannot change form does nothing. This ability to change form allows 4D prints to not only occupy three-dimensional space, but also the additional dimension of time. A 4D print also occupies space three-dimensionally, but unlike 3D printing it can also change its shape, color, or other properties over time after being printed. It occupies space as height, length, and width, hence its three dimensions. What is 4D Printing?Ĭonventionally, a 3D print is complete and unchangeable once printed. That right off the bed, the parts can transform from one shape to another shape directly on their own.”Ī 4D printed part that changes shape in water. The idea behind 4D printing is that you take multi-material 3D printing, so you can deposit multiple materials, and you add a new capability, which is transformation. “So, remember I said 4D? So today for the first time, we’re unveiling a new project, which is a collaboration with Stratasys, and it’s called 4D printing. When Was 4D Printing Invented?Īn exact date for the technology’s invention is difficult to pinpoint, however the term “4D printing” became used widely after it was coined by Skylar Tibbits during a Ted Talk in 2013. With furniture that can build itself, undulating pipes and transforming art installations all functional straight off the print bed, it’s worth looking at how 4D printing is bringing a new dimension to the industry. Although that reality is still far off, a new technology, 4D printing, may allow us to entirely 3D print objects that have until now been impossible. As 3D printing technology continues to push the envelope with the kinds of objects that can be printed, it edges closer and closer to something more akin to a Star Trek Replicator, able to “print” essentially anything.
