Though it is designed with the fans of the Terminator movies in mind, this 3D-printed arm could give us a glimpse into the future of prosthetics. Highlighted at the London Science Museum's 3D printing exhibition, the arm was designed by Richard Hague, director of the University of Nottingham's additive manufacturing and 3D printing research group. The model printed in clear plastic shows in detail how it would work. The circuits can sense temperature, feel objects, and control the arm's movement. (Source: NewScientist.com)
Thanks for the history lesson, Chuck. I've been wondering where this techology came from. It seemed like it popped out of nowhere. As well as being an attractive name, 3D printing clearly describes the object's function.
Good news, whic is that those expensive spools of plastic are not at all the only way to print with plastic. A mechanisation quite similar to a hot glue gun can dispense small drops of molten plastic, which can be from ordinary regrind plastic. LOts cheaper and available in a whole lot more places. And the mechanism may even be simpler than the feed for the plastic string stock. The main downside is needing to reload a bit more often. But extruding drops of melted regrind is a great way to make things indeed.
Yes, 3D printing has been around a while. Part of the recent explosion in interest in it stems from the name -- 3D printing. I wrote about stereolithography 20 years ago and there wasn't much interest in it. Similarly, the use of the terms "selective laser sintering" and "fused deposition modeling" didn't send anyone's heart racing, either. But the name "3D printer" captured the public's interest, and captured the interest of the mainstream press, even though many "3D printers" don't look like printers at all. The clever name will ultimately allow the world to consider it long enough to see the amazing things a that an FDM machine or SLS machine can do.
I think the prosthetic hand points to the future. Imagine if stem cells taken from your body could be grown and printed to form a new replacement body part that was genetically the same as the owner. There would be no rejection issues. I believe this will happen, just a matter of time.
With strong marketplace demand for qualified engineers across the board that currently outstrips the available supply, there may never be a better time for engineers and project managers to advance their careers and salaries. Whether those moves are successful in the short-term and long-term is likely to depend on how the transition from one job to the next is handled.
There are drivers everywhere who turn on their headlights or windshield wipers with no awareness of the development effort behind a switch. Yet from freezing winter to sweltering summer, on dull rainy days and in bright sunshine, switches are expected to function consistently for the lifetime of a car.
The standards electrical machines and components are required to meet in the food processing industry are far more stringent than those in traditional plant construction. For specialized production environments such as these, components must not only resist thermal and physical stresses, but they must also be resistant to the chemicals used to sterilize equipment.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
