One of the themes at the Medical Design and Manufacturing West event being held this week in Anaheim, CA is tiny. Medical devices are becoming smaller. That’s putting a lot of pressure on suppliers to provide precise tolerances. One of the interesting examples of the trend is a display from Kyocera showing its capability to achieve dimensional tolerances of ±0.002-inch on powder molded ceramic parts used in electro surgical devices. Kyocera can also achieve ±0.01-inch minimum wall thickness, says Hideki Ohnishi, manager of fine ceramics marketing at Kyocera. Achievement of the precise dimensions is possible because of custom made powder slurries as well as tweaking of the injection molding process, according to Ohnishi. Particular attention is paid to gate locations and venting. Kyocera operates 15 injection molding machines in Japan for the ceramic process. Ohnishi said that Kyocera will be almost doubling capacity due to strong demand for the products. Press sizes are 30 or 60 tons of clamping force. Typical part sizes are half-inch cubes.
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.
