“Desktop 3D Printer Offers Speed, Precision, Ability to Work in Metal” Featured on D2PMagazine.com Airwolf 3D calls its newly released EVO a rugged ‘additive manufacturing center’ that is powered by an automotive-grade microcontroller FOUNTAIN VALLEY, Calif.—Airwolf 3D recently released EVO, its 5th generation 3D printer that is said to be so advanced that Airwolf calls it a desktop “Additive Manufacturing Center,” or AMC. “The EVO is completely new and it’s unlike anything out there,” said Airwolf 3D Co-Founder and CEO Erick Wolf, in a company release. “We took the technology that we perfected with our prosumer line of 3D printers and leveraged it to develop a machine that’s light years beyond anything else on the market. The EVO is faster, stronger, and more accurate than any desktop 3D printer—it delivers a premium 3D manufacturing experience at less than half the cost of machines that offer equivalent performance. Plus, it’s packed with new technology that dramatically changes the way we manufacture, including the ability to work in metals. The EVO far surpasses the capabilities of a traditional desktop 3D printer. It’s a true desktop Additive Manufacturing Center.” The EVO possesses Airwolf 3D’s signature suite of features—auto-leveling, large build size, high-temperature multi-material printing, and compatibility with water-soluble Hydrofill support material—but in an ultra-ruggedized unit that includes cutting-edge features available only from Airwolf 3D. Most notable among these is the industry-first PartSave™. Nicknamed “Zombie Mode,” PartSave solves one of the most frustrating problems with 3D printing. There are few things more disheartening than 3D printing a part for hours, only to have it fail completely if the printer stops because of a power outage or unplugging the machine. With PartSave, once power is restored, the machine resumes where it left off, enabling the part to finish. Another industry-first feature, the company said, is FailSafe™. If you run out of filament or experience a jam, FailSafe™ has you covered. Just place the print head at the height you left off and FailSafe will do the rest, restoring your print and completing the job with time to spare, according to Airwolf. The EVO also ships with a full-color 7–inch Matrix touchscreen display, new Tri-Heat™ Enclosed Build Environment, an oversized...

Smart manufacturing technology is changing business…

“Smart manufacturing technology is changing business processes” By Jim O’Donnell, TechTarget The future is here: AI enablement and smart manufacturing technologies are transforming business systems today, according to technology futurist Jack Shaw. Imagine a scenario where a plane in midflight from Paris to Boston gets a signal from an embedded sensor in an engine fuel nozzle that indicates excessive wear. Once the plane lands, it will need to be taken out of service for hours or even days as the airline locates and installs a replacement part. The entire process is time-consuming, expensive and inconvenient for passengers and crews. But thanks to smart manufacturing technology and AI-enabled business processes and systems, there is a better way, according to technology futurist and consultant Jack Shaw. The digital transformation to an AI-enabled business ecosystem is happening now, Shaw said in a presentation at the Smart Manufacturing Experience conference this month in Boston. An autonomous self-contained process Rather than the current costly and time-consuming process, the smart manufacturing technology ecosystem encompasses a self-contained and autonomous parts replacement process. To start the process, industrial IoT (IIoT) smart sensor circuitry in the engine’s nozzle triggers the aircraft’s autonomous maintenance system, which then messages the airline’s global maintenance system that the part will be needed when the plane lands in Boston, Shaw said. The airline’s global procurement system is notified. It scours thousands of websites to identify Federal Aviation Administration (FAA)-certified parts suppliers, negotiates the terms with the supplier’s AI-enabled order management system and executes a smart contract to procure the part. Once the procurement contract is authorized, a design file of the fuel nozzle part is downloaded to a 3D printer located near the Boston airport. The entire process — from the identification of a part defect to the design download to the 3D printer — takes less than four minutes and requires no human intervention, according to Shaw. But the smart manufacturing technology and AI-enabled ecosystem is not finished. Automatic procurement processes identify and select technical engineers who are experienced with replacing this particular part and available to do the work. The technical engineer who installs the part then uses augmented reality (AR) goggles that display a 3D video of the entire replacement process directly on...

How Factory Intelligence is Evolving

How Factory Intelligence is Evolving

May 23, 2018

By Larry Maggiano, Senior Systems Analyst, Mitutoyo America Corp. Featured on AdvancedManufacturing.org Intelligent factories have existed since manufacturing’s historical inception, but intelligence—defined as the acquisition and application of manufacturing knowledge—resided only with the factory’s staff. With the advent of numerical control (NC) and then computer numerical control (CNC) technologies, factory machines gained digital I/O capabilities but were still not smart. Digitally enabled machines, though increasingly productive, had no awareness of themselves, their environment, or the tasks being performed or to-be performed. In spite of these limitations, centralized factory intelligence has been achieved at modest scales through a deterministic low-level set of digital commands and responses. An experiment in large-scale centralized factory intelligence was General Motor’s 1982 Manufacturing Automation Protocol (MAP), operating over token bus network protocol (IEE 802.4). The MAP-enabled factory intelligence experiment ended in 2004 as it was difficult to maintain operational reliability. One of the most important reasons was a lack of system resiliency, a downside of required deterministic factory communication standards and protocols. Another reason was that the connected machines could not continue to operate at any level when instructions were not forthcoming from a central system. An analogy might be made to the mainframe-to-terminal infrastructure that became obsolete in the 1990s with the development of the PC and distributed computing. Several significant changes have enabled the development of smart machines for the intelligent factory. The first is the extension of IT’s ubiquitous Ethernet LAN infrastructure to the shop floor, enabling rapid 3D downloads of model-based definition (MBD), and uploads of process and product data. Secondly, today’s digital twins are smart in that they possess an awareness of not only their capabilities and operational status, but of work that can be performed on any particular MBD. In this manner, smart machines can bid on tasks, much like their human partners. A smart machine’s digital twin does not need deterministic low-level instructions, but instead responds to a submitted MBD, and, if selected, does real work with its physical counterpart. Lastly, three standardized core technologies–HTML, CSS and JavaScript—are recognized as enabling the widespread adoption of the Internet and the emergence of intelligent global systems. It is envisioned that similar standardized core technologies will enable...

The Four Slide Metal Stamping Advantage

The Four Slide Metal Stamping Advantage

May 9, 2018

By ThomasNet.com  Metal stamping is used to turn cold sheet metal and other materials — such as copper and brass — into high-performing products and parts that can be used in various industrial and manufacturing processes. Traditionally, power press stamping machines are built to blank and stamp metal parts; these machines are ideal for simple, straightforward operations. Progressive die stamping improved on power press stamping machines by allowing for the completion of various operations, such as punching, coining, and bending. Multi-slide stamping machines then further improve the die stamping process by allowing for the production of highly complex shapes and bends. The four slide metal stamping machine is one such machine, although the terms “multi-slide” and “four slide” are often used interchangeably. How Does Four Slide Metal Stamping Work? Power press stamping and progressive die stamping both utilize an up-and-down, or vertical, motion when processing sheet metal and other materials. These stamping methods are geared toward the production of less complex parts. Multi-slide metal stamping, including four slide metal stamping, is different; these machines work in right angles, or horizontally. The slides, or rams, in the machines, strike the sheet material to produce the finished product. Multi-slide stamping machines may have more than four multiple moving slides, while four slide metal stamping machines have a fixed number. Servo motors or cams act on the slides, allowing the workpiece to be worked from four sides. The Benefits of Using a Four Slide Metal Stamping Machine Since different tools can be attached to the slides in a four slide metal stamping machine, it is much more versatile than a stamping press. Four slide equipment is also able to handle the manufacture of much more complicated parts, including parts with multiple, complex, or over 90° bends and twists. A huge range of parts can be produced using four slide metal stamping, including flat springs, clips, brackets, shunts, friction plates, terminals, and retainers. Both flat and round materials can be formed. Moreover, four slide metal stamping machines are much more cost-efficient than other stamping machines. The tools needed for four slide stamping are often cheaper than those required by other stamping methods, and die sets are not required....

Researchers 3-D print electronics and cells directly on skin

Researchers 3-D print electronics and cells directly on skin

May 7, 2018

By The University of Minnesota Featured on Phys.org One of the key innovations of the new 3-D-printing technique on skin is that the printer uses computer vision to track and adjust to movements in real-time. Credit: McAlpine group, University of Minnesota In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics. Researchers also successfully printed biological cells on the skin wound of a mouse. The technique could lead to new medical treatments for wound healing and direct printing of grafts for skin disorders. The research study was published today on the inside back cover of the academic journal Advanced Materials. “We are excited about the potential of this new 3D-printing technology using a portable, lightweight printer costing less than $400,” said Michael McAlpine, the study’s lead author and the University of Minnesota Benjamin Mayhugh Associate Professor of Mechanical Engineering. “We imagine that a soldier could pull this printer out of a backpack and print a chemical sensor or other electronics they need, directly on the skin. It would be like a ‘Swiss Army knife’ of the future with everything they need all in one portable 3D printing tool.” One of the key innovations of the new 3D-printing technique is that this printer can adjust to small movements of the body during printing. Temporary markers are placed on the skin and the skin is scanned. The printer uses computer vision to adjust to movements in real-time. “No matter how hard anyone would try to stay still when using the printer on the skin, a person moves slightly and every hand is different,” McAlpine said. “This printer can track the hand using the markers and adjust in real-time to the movements and contours of the hand, so printing of the electronics keeps its circuit shape.” Another unique feature of this 3D-printing technique is that it uses a specialized ink made of silver flakes that can cure and conduct at room temperature. This is different from...
