3D printing of patterned membranes opens door to rapid advances in membrane technology
Penn State Materials Research Institute via Science Daily: A new type of 3D printing developed by researchers at Penn State will make it possible for the first time to rapidly prototype and test polymer membranes that are patterned for improved performance.
Ion exchange membranes are used in many types of energy applications, such as fuel cells and certain batteries, as well as in water purification, desalination, removal of heavy metals and food processing. Most ion exchange membranes are thin, flat sheets similar to the plastic wrap in your kitchen drawer. However, recent work has shown that by creating 3D patterns on top of the 2D membrane surface, interesting hydrodynamic properties emerge that can improve ion transport or mitigate fouling, a serious problem in many membrane applications.
Currently, making these patterned membranes, also called profiled membranes, involves a laborious process of etching a silicon mold with the desired pattern, pouring in the polymer and waiting until it hardens. The process is both time-consuming and expensive, and results in a single pattern type.
“We thought if we could use 3D printing to fabricate our custom-synthesized ion exchange membranes, we could make any sort of pattern and we could make it quickly,” says Michael Hickner, associate professor of materials science and engineering at Penn State. Cont'd...

China's Big Bid For Germany's Industry 4.0 Technology
Klaus E. Meyer for Forbes: Midea, the Chinese household appliances (“white goods”) manufacturer just made what analysts called an ‘incredibly high’ bid for German robot maker Kuka. This acquisition would take the Chinese investor right to the heart of Industry 4.0 : Kuka is a leading manufacturer of multifunctional robots that represent an important building block for enterprises upgrading their factories with full automation, the latest human-machine interface functionality, and machine-to-machine communication. Midea want a 30% stake in Kuka and have offered €115 per share. Kuka’s shares traded at €84 the day before and had already increased 60% since the beginning of the year. This offer values Kuka at €4.6 billion, which means Midea’s 30% stake would be worth €1.4 billion – on par with Beijing Enterprise’s February 2016 takeover of recycling company EEW which was the largest Chinese acquisition of a German firm to-date.
Midea’s takeover bid underscores Chinese interest in German Industry 4.0 technology; in January 2016, ChemChina paid €925 million for Munich-based KraussMaffei machine tools, in part because of their advances into Industry 4.0. Recent smaller Chinese acquisitions in the German machine tool industry, which include the partial acquisitions of H.Stoll by the ShangGong Group and of Manz by the Shanghai Electric Group are, in part, motivated by the objective to partake in the latest Industry 4.0 developments.

German manufacturers take aim at smart factories, mass customization
TOMOHISA TAKEI, Nikkei staff writer: It has been five years since Industry 4.0, the fourth industrial revolution, was first unveiled at the Hannover Messe industrial technology trade fair in Germany.
Industry 4.0 was more of a conceptual model at that time. This year, however, the trade show witnessed an emerging trend toward "smart factories" that can provide mass customization.
On April 25, SEW-Eurodrive's booth at Hannover Messe drew crowds of visitors. The German industrial motor maker demonstrated its automated vehicles for next-generation assembly plants, what it calls the "Lean Smart Factory."
In SEW-Eurodrive's demonstration, about 10 such "smart vehicles" moved about as five workers assembled products. One vehicle approached its target worker, displayed a procedure on its screen and instructed the worker to do the assembly work. After the worker completed the task, the vehicle received the product and moved on to another worker in charge of the next process.
These smart vehicles were connected over a network and programmed at the company factory. But it looked as if the products themselves were driving the vehicles and moved to where the tasks needed to be done. SEW-Eurodrive has already introduced the system at its factory in the southwestern German town of Graben-Neudorf, intending to make individually tailored products in the future. Cont'd...
These Five Exponential Trends Are Accelerating Robotics
Alison E. Berman for Singularity Hub: If you've been staying on top of artificial intelligence news lately, you may know that the games of chess and Go were two of the grand challenges for AI. But do you know what the equivalent is for robotics? It's table tennis. Just think about how the game requires razor sharp perception and movement, a tall order for a machine.
As entertaining as human vs. robot games can be, what they actually demonstrate is much more important. They test the technology's readiness for practical applications in the real world—like self-driving cars that can navigate around unexpected people in a street.
Though we used to think of robots as clunky machines for repetitive factory tasks, a slew of new technologies are making robots faster, stronger, cheaper, and even perceptive, so that they can understand and engage with their surrounding environments. Consider Boston Dynamic’s Atlas Robot, which can walk through snow, move boxes, endure a hefty blow with a hockey stick by an aggressive colleague, and even regain its feet when knocked down. Not too long ago, such tasks were unthinkable for a robot.
At the Exponential Manufacturing conference, robotics expert and director of Columbia University’s Creative Machine Labs, Hod Lipson, examined five exponential trends shaping and accelerating the future of the robotics industry. Cont'd...
46% of German companies use Industry 4.0 - survey
Almost one in two companies in the manufacturing sector (46%) use Industry 4.0 applications, while another 19 percent have specific plans to implement them, according to a recent Bitkom survey among 559 industrial companies with more than 100 employees. About 65 percent of the German industrial companies are already active in the Industry 4.0 sector.
Around 23 percent of the companies asked have no concrete plans to use Industry 4.0 but will consider use for the future. Only 12 percent stated that this is not an issue currently.
The study also showed that companies are still careful when it comes to investments: although 57 percent of the companies use or plan to use Industry 4.0, the budget for this is on average only 4 percent of the total revenue.
Users and planners of Industry 4.0 primarily aim to optimise processes (69%) and to improve the capacity utilisation of their factories (57%). Half of the respondents expect a faster realisation of their customers’ individual wishes. 44 percent want to reduce their production costs with Industry 4.0 and 19 percent their personnel costs.

The Questions Executives Should Ask About 3D Printing
Channing Flynn for Harvard Business Review: Most hearing aids in the U.S. are now custom-made on 3D printers. The U.S. Food and Drug Administration recently approved the first 3D-printed pills. Carmakers have started using 3D technology to produce parts. And last year saw the first demonstration of a digital printer producing multilayer, standards-based circuit boards. Imagine the changes afoot in the pharmaceutical, medical device, automotive, and consumer electronics industries.
3D printing is poised to redefine global manufacturing and distribution. It could upend supply chains, business models, customer relationships, and even entrepreneurship itself. It may do to physical goods what cloud computing is now doing to digital services; what the PC, internet, and smart mobility have done to personal computing; and what outsourcing did to software development and business processing — take mass distribution and innovation to the next level while realigning the very geography of work and trade.

Swagway Teardown: What Makes a Safe Hoverboard?
From Andrew Goldberg at Ifixit.org:
The board is also smart enough to not drive around without you. Riders need both feet firmly planted on the board or it won’t be going anywhere. Just how does the board know you’re properly mounted? Each foot pad has two infrared sensors—one at the toe, one at the heel. Stepping down on the pad pushes a peg between emitter and receiver. Only when all four sensors are blocked are you ready to roll...
...Those sensor switches live on the backs of the two gyro boards—one for each wheel. These boards are largely responsible for the “smart” part of smartboard. Each board is home to an Invensense MPU6050 6-axis gyroscope+accelerometer, and a GigaDeviceGD32F130 ARM Cortex-M3 32-bit microcontroller (thanks, Ken!). The ARM chips are responsible for reading the infrared switches, controlling the sweet underglow headlights and top-mounted indicator LEDs, and collating and sending data from the MPU6050 to the main board (more on that later)...

U.S. manufacturing isn't dead; factories are running at close to a record pace
Rex Nutting for MarketWatch: U.S. manufacturing sector doesn’t get any respect.
Ask a random sample of people on the street and you’re likely to hear that America doesn’t make anything anymore, that China, Mexico and Vietnam took all of our factories, and that the only jobs left in America are flipping burgers and cleaning hotel rooms.
“Throughout history, at the center of any thriving country has been a thriving manufacturing sector,” says presidential candidate Donald Trump. “But under decades of failed leadership, the United States has gone from being the globe’s manufacturing powerhouse — the envy of the world — through a rapid deindustrialization.” Cont'd.. .
