News reports drone on constantly these days with more and more negative information. I don’t get the same kind of vibe when I talk to design engineers every day for my writing about materials and fastening technology for Design News. Most incredible to me are reports on advances in medical technology by American inventors and engineers. The most recent was an interview I had with Dave Danitz, the vice president of research and development at Novare Surgical Systems In California, which recently developed and brought to market an instrument called RealHand that allows laparoscopic surgery through a single port—and even through natural orifice such as a mouth. The result is a dramatic reduction in the risk of infection.
Invented by Danitz, the RealHand is a fully mechanical instrument up to 45 centimeters in length in which jaws at the distal end move inside the human body in reaction to movements of a surgeon’s hands on a handle. Small articulating links connect the jaws to the shaft and the handle to the shaft, which can vary in length from 24 to 45 centimeters. There are no electronics in the device.
Although introduced just six months ago, a number approaching 100 surgeons use the tool.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
