White Paper: Seven Key Enabling Application Technologies For A Wide Range Of Engineering Applications
Metal bellows play an essential role in controlling pressure, vacuum, motion and more in a broad array of machine components and assemblies across numerous industries. The whitepaper showcases seven engineering applications that can benefit from the use of bellows, and demonstrates the broad functionality of bellows in different engineering scenarios. Engineers are provided with important specifications (in terms of requirements and restrictions) that must be considered for an application.

Advances in multimaterial printheads pave way for next frontier in 3D printing
The ability to integrate disparate materials and properties within printed objects is the next frontier in 3D printing. Toward this objective, Harvard researchers have designed new multimaterial printheads that mix and print concentrated viscoelastic inks that allow for the simultaneous control of composition and geometry during printing. Using active mixing and fast-switching nozzles, these novel printheads change material composition on the fly and could pave the way for entirely 3D-printed wearable devices, soft robots, and electronics.

Mobile Machines: Options for driving hydraulic pumps
Manufacturers of both on- and off-highway equipment must consider the desired functionality of the machine while evaluating the best approach to transfer the engine power to the desired function. The pump drive is a key decision in the layout of the machine and overall performance for the OEM.

New model predicts the force required to tie simple knots
Researchers at MIT and Pierre et Marie Curie University in Paris have analyzed the mechanical forces underpinning simple knots and come up with a theory that describes how a knot's topology determines its mechanical forces.

NASA tests acrylics for Orion spacecraft windows

When astronauts travel to an asteroid and toward Mars in NASA’s Orion spacecraft, they’ll get a tremendous view of their deep-space destinations and of Earth through the spacecraft’s windows. NASA engineers are making sure those windows will be more structurally sound, lighter, and cheaper than on previous spacecraft.

Mike Likes: 3D printer uses paper not plastic
The Mcor IRIS HD provides 360-degree high-definition color, sharpens details, and reduces the industry’s already lowest operating costs for 3D printing by 20 percent. How can one printer do all that? It uses paper to make the models: 1. Each layer of a design is printed on a sheet of paper using high-saturation inks. 2. The stack of paper is put into the "printer," where each piece is carefully edge-glued with special adhesives and cut. 3. The model stack grows. 4. Pop your finished color model out of the precision glued and cut stack. Paper-based 3D models are serious prototyping contenders, because the model cost is so low: often around 10 bucks or less a pop.

Engineer's Toolbox:
How topology optimization can create better material, design in high-consequence uses

Sandia National Laboratories researchers believe that organically shaped designs, achieved through a technology called topology optimization, could enable better parts for national security systems and other vital uses. Coupled with advanced additive manufacturing, familiar to most people in its 3D-printing incarnation, it opens possibilities for complex shapes that conventional manufacturing methods can’t handle. Along the way, researchers are doing some serious questioning and testing of the tiniest details of what really happens to materials when they are 3D printed.

Image - Why plastic bearings outperform metal
Why plastic bearings outperform metal
Plastic bearings cost and weigh less than their metal counterparts. And they often run longer in harsh environments and under adverse conditions. Plain bearings molded of plastic are often an economical replacement for needle, ball, and plain metal bearings. To a certain extent, though, plastic bearings face an uphill battle for respect among the engineering community.

Motors: Simplified small motor load overload protection
Power management company Eaton has launched a competitively priced, enclosed manual motor starter with hand-off-auto (HOA) functionality and run-light indication. Designed to meet the needs of contractors, original equipment manufacturers (OEMs), and distributors in the construction and HVAC markets, this compact, cost-effective package solution is designed to enable both local and remote-control capabilities of 1-hp, single-phase motor applications where overload protection is required. With this compact solution, customers will no longer need to order three separate parts to assure overload protection for small motor power loads up to 16 A at 120 V to 240 V.

Carbon fiber composite for robust vehicle parts
Covestro (formerly Bayer MaterialScience) has developed a new Baydur matrix system for carbon fiber structural components in cars that has three times the energy absorption potential of comparable resins, so it is able to provide an extremely high level of occupant safety in the event of a collision. Covestro expert Karine Benbelaid shows the prototype of a component, which was manufactured using the efficient high-pressure resin transfer molding process (HP-RTM). The HP-RTM process has proved very effective for manufacturing robust composite parts in volumes in the low hundreds of thousands. Carbon fiber content is approximately 54% by volume.

High-speed 3D printing aims to take on injection molding
The world’s first additive manufacturing (3D-printing) machine that can make plastic parts as fast and cheaply as traditional manufacturing is being built by the University of Sheffield in the UK. The machine will build parts up to three times larger and 100 times faster than current comparable additive manufacturing (AM) machines, making it capable of challenging conventional injection molding for high-volume production.

Ford F-150 features super alloy and mega-fast aluminum processing

Ford is using Alcoa’s Micromill material in multiple components on the 2016 F-150, becoming the first automaker to use the advanced automotive aluminum, which has 40% greater formability and 30% greater strength than the incumbent aluminum used today, commercially. On the process side, a traditional rolling mill takes around 20 days to turn molten metal into coil; Micromill does it in just 20 minutes.

Videos+: Technologies and inspiration in action
Stealth and aerodynamic design
ANSYS solutions enable the creation of complete virtual prototypes for the exploration of the trade space between aerodynamics, propulsion intakes, and radar cross-section performance of advanced stealth aircraft, subsystems, and components. This enables companies and engineers to develop products faster, test designs earlier in the development cycle, reduce the number of physical prototypes, and produce an optimal solution quicker. Watch the video to see ANSYS solutions in action for the integrated, multiphysics design exploration of aerodynamic, observability, and propulsion system performance of a representative generic stealth aircraft.

What does Alka Seltzer do in space?
Astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos give researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA's Marshall Space Flight Center in Huntsville, AL.
