PowerAc TMtrapezoidal screws from Nook Industries have centralizing threads that maintain alignment of the thread axis. The screws are manufactured in accordance with ISO standards. "We are finding more customers designing with global sales in mind, so they are asking for metrics," says Rick Christyson, chief engineer at Nook. The company offers eight sizes from 10 to 65 mm. The screws are accurate to within±0.1 mm per 300-mm lead. "The screw's threads are made with a 30ºangle. We make the nuts to match, so there is no wedging or binding. Keeping the tolerances tight also lowers the friction and extends the life of the products," says Christyson. Plastic and bronze nuts are matched with screw capacities. Customers choose trapezoidal screws made from stainless steel for food and medical applications or high-carbon 4140 alloy steel for machine tool, packaging, and other industrial applications. PowerAc screws are compatible with the company's EZZE-MOUNT™bearing supports for 16-, 20-, 26-, 40-, 55-, and 65-mm universal face/foot-mount bearing supports and 16-, 20-, 26-, 40-, and 55-mm flange-mount bearing supports.

Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
