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.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
