Four ultra-futuristic printers and scanners

How we will print and scan in the future

Biological printers

We are still a little way off re-growing entire limbs, but we are certainly making strides towards it. Invetech and Organovo have created the first 3D bioprinter, which is capable of printing entire cells. According to Organovo CEO Keith Murphy, the potential uses are wide-ranging — from supporting existing kidney cells to forming the foundations of a tooth.

With a printer capable of producing "tissue on demand," researchers and surgeons will apparently be able to easily repair organs without waiting for a lab to catch up; just press the button and go. It's all a bit freaky, but if these end up in every hospital they could literally be a life saver.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
