Video: Sciaky to Sell Its Huge Metals 3D Printers
News 7/31/2014 6 comments Sciaky, provider of electron-beam additive manufacturing (EBAM) services, will start selling these machines commercially in September. The company has used its EBAM 3D printing technology for making very large, high-value, metal prototypes and production parts for aerospace and defense OEMs.
3D-Printed Rocket Engine Fires Up
Engineering Materials 7/14/2014 19 comments Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
Video: Wear Your Own Pair of Robot Arms
Engineering Materials 7/10/2014 53 comments Researchers at MIT's d'Arbeloff Laboratory are developing shoulder- and hip-mounted robotic arms to help workers in aircraft manufacturing perform difficult or complex assembly tasks that would normally require two people.
Video: Power Line Perching UAV Doubles Down on Drone Delivery
Blog 7/8/2014 21 comments Last December Amazon.com unveiled a plan for a delivery system of drones that can deliver packages to people living within 10 miles of a distribution center. One of the reasons for that mileage limit is that the unmanned aerial vehicles the company plans to use only have enough battery life to cover that distance without recharging. MIT is out to change that.
10 Engineering-Friendly Foods
Blog 7/3/2014 38 comments Normally it’s chefs who find inspiration in food. But a number of clever engineers and inventors are doing the same these days, developing new materials, biofuels, ways to harvest energy, and other inventions by using common foods and food waste to create the foundation or impetus for their designs.
3D-Printed Steel Building Structures
Engineering Materials 7/2/2014 22 comments Structural engineers have developed a design method for 3D printing structural steel elements to be used in construction projects. Complex, individually designed pieces can be created far more efficiently, and costs and waste will be reduced.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
