Three-dimensional printing, also known as additive manufacturing, takes a digital blueprint and turns it into a physical object using computer-aided design (CAD). A repeating 2D structure is built up, ...

Imagine having your curtains extended or retracted automatically without needing to lift a finger? Reversible 4D printing technology could make these 'smart curtains' a reality without the use of any ...

Researchers worked to revolutionize 4D printing by making a 3D fabricated material change its shape and back again repeatedly without electrical components. Reversible 4D printing technology could ...

Whilst 3D printing continues to grow in popularity, some scientists are already looking at the next step – how to make their objects transform from one shape to another using 4D printing. Essentially, ...

Gutenberg’s printing press revolutionized the way the written word was replicated, bringing two-dimensional printing into the world and so vastly increasing accessibility of information. From that ...

The days when 3D printing was simply dreamed about are far behind us. Today, the process of creating a three-dimensional object via successive layers of materials is a mainstream activity—from ...

These tiny objects made with 3D printers can dramatically expand when exposed to heat. Scientists have created a pair of compact, unfurling structures that could pave the way for innovations in ...
