With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

Using a new technique known as 4D printing, researchers can print out dynamic 3D structures capable of changing their shapes over time. Such 4D-printed items could one day be used in everything from ...

Nowadays, 3D printing allows items to be created from a wide variety of materials — plastic, ceramic, glass, metal and even stranger ingredients such as chocolate and living cells. The machines work ...

Three dimensional printing is about to become so passé – welcome to the world of 4D printing. A team of scientists has created a technique for printing objects that can change their shape over time ...

Now, 4D technology has been used to create a soft robot capable of analyzing the soil. Drawing inspiration from the seed structure of the South African geranium (Pelargonium appendiculatum), which ...

Move on over 3D printing, because 4D printing is taking the spotlight. (WATCH FULL VIDEO BELOW, transformation near end of clip) Scientists at Harvard University created a new 4D printing method— ...

During the early stages of life, organs do not just appear in their final form. They take shape through a process of controlled bending, twisting, and folding. These changes help cells organize into ...

A recent article published in Small Science introduces fully bioderived, four-dimensional (4D) printable shape memory polymers (SMPs) with linear tunability and remotely controlled actuation ...

Consider the humble pinecone. Found scattered on forest floors and covered in woody scales, the pinecone is a perfect example of nature’s clever shape-shifting engineering. When it is wet and humid, ...
