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.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
