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 ...

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 ...

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 ...

History in 3D

(PhysOrg.com) -- Three-dimensional computer graphics is moving into museums. Works of art are being digitally archived in 3D, simplifying research into related artifacts and providing the public with fascinating three-dimensional ...

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 ...
