Materials Spotlighted at Design & Manufacturing Show
Engineering Materials 8/29/2013
The choices of metals, plastics, coatings, and adhesives has never been broader, and new ones are becoming available at a rapid rate. Some of this variety is reflected at the upcoming Design and Manufacturing Midwest Show.
3D Printing With Iron & Tungsten
Engineering Materials 8/26/2013
The range of metals that can be 3D printed is increasing. ExOne has added iron infiltrated with bronze, and bonded tungsten, to the range of metal and ceramic powders that can be used with its multi-material M-Flex machines.
Video: Inside the World's Largest Wind Tunnel
Electronics News 8/23/2013
When NASA Ames runs its massive wind tunnels, the surrounding area knows it. Local aircraft are warned of potential updrafts. Electric utilities brace for sudden power draws. And nearby residents are said to hear its 300-knot airflows from miles away.
Slideshow: Robots Get More Thin-Skinned
Engineering Materials 8/22/2013
Robots may be getting more sensitive, due to a breakthrough by engineers at the University of California, Berkeley. An electronic skin made of a sensor network mounted on a substrate of flexible plastic reacts to touch by lighting up.
DuPont Pushes for a 50%-Plus Renewable Plastics Line
Engineering Materials 8/9/2013
DuPont says its performance plastics line will contain more than half renewable materials within 15 years, and that all of its medium- to long-term research in engineering plastic feedstocks is based on the need to move to non-food based sources.
MIT 3D Prints Tough, Bone-Like Composite
Engineering Materials 8/8/2013
A team at MIT has 3D-printed bone-like composite materials on the Objet Connex500 multi-material printer. One was more than 20 times as tough as its constituent materials alone.
How to Make Intelligent Carbon-Fiber Composites
Engineering Materials 8/7/2013
German researchers have demonstrated the ability to embed RFID tags with ultra-thin antennas inside carbon-fiber-reinforced composite components such as aircraft wings. The technique is also being investigated for composite structural health monitoring.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
Researchers have developed a hybrid energy harvester for generating electricity from multiple spectrums of solar energy.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
These futuristic military robots will help soldiers and other military personnel better perform their duties.
Icon Labs has developed a whitepaper to help determine the type of cybersecurity needed based on the type of device.
