Scientists use bacteria as micro-3-D printers

A team at Aalto University has used bacteria to produce intricately designed three-dimensional objects made of nanocellulose. With their technique, the researchers are able to guide the growth of bacterial colonies through ...

3D-printer with nano-precision

Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University ...

Augmented reality in retail and its impact on sales

Augmented reality (AR) is a technology that superimposes virtual objects onto a live view of physical environments, helping users visualize how these objects fit into their physical world. Researchers from City University ...

Simulating and optimizing industrial spinning processes

Spinning polymer filaments, for example for personal care articles, is highly complex: simulating the processes involved is too much for currently available computing power to handle. Fraunhofer researchers have successfully ...

Who can find the fish that makes the best sound?

Using new computer algorithms, it is possible to adjust specific properties of three-dimensional objects, such as the sounds they produce or how stable they are.

Review: Autodesk's 3-D technology cool but frustrating

Last week, Autodesk updated its suite of 3-D printing and modeling applications, releasing an iPad version of 123D Catch, a program that creates a virtual object by stitching together two-dimensional photographs taken of ...

Mathematics: First-ever image of a flat torus in 3D

Just as a terrestrial globe cannot be flattened without distorting the distances, it seemed impossible to visualize abstract mathematical objects called flat tori in ordinary three-dimensional space. However, a French team ...
