“Direct Metal Printing Is Key to Bringing First-of-its-Kind Faucet to Market” Featured on D2PMagazine.com ROCK HILL, S.C.—Kallista, a designer and provider of luxury kitchen and bath products, unveiled its Grid™ sink faucet at KBIS 2018 earlier this year. 3D Systems’ Direct Metal Printing technology was instrumental in bringing the first-of-its-kind sink faucet—produced by 3rd Dimension using 3D Systems’ 3D printing materials and technology—to market. According to a release from 3D Systems (www.3dsystems.com), its technologies enabled Kallista to “design without limitations” in its efforts to bring the product to market. Kallista’s design team embarked on a journey to create a faucet in a unique geometry. In deciding to produce the spout via 3D printing, the designers were able to design without limitations to create an open form and discrete interior channels that allow water to flow easily through the base. “Designers usually need to consider a manufacturing process, and they have to design around that process,” said Bill McKeone, design studio manager at Kallista, in a statement. ”By choosing to produce this faucet via 3D printing, we opened ourselves to limitless design possibilities. 3D Systems’ breadth of materials and technologies allowed us the freedom to create a unique, functional faucet which would not have been possible with a traditional manufacturing process.” The faucets were produced by metal 3D printing specialist, 3rd Dimension, a production metal manufacturer specializing in 3D direct metal printing based in Indianapolis. 3rd Dimension (print3d4u.com) employed 3D Systems’ ProX® DMP 320 high-performance metal additive manufacturing system. To avoid rust and corrosion, the faucets are printed with 3D Systems’ LaserForm® 316L, a high quality stainless steel 316 powder material. “In order to realize the best product, you have to start with the best tools,” said Bob Markley, president, 3rd Dimension, in the release. “The strength of the 3D Systems technology and materials, coupled with the expertise of our engineers and machinists, allowed us to rapidly produce and deliver these high end faucets for Kallista.” As this was the first additively manufactured product for Kallista, the team at 3rd Dimension led them through a program to develop the as-designed concept for the 3D printing process. Developing the design for additive manufacturing meant that Kallista was able to avoid the...

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...

Putting the ‘smart’ in manufacturing

Putting the ‘smart’ in manufacturing

Apr 11, 2018

By Silke Schmidt, University of Wisconsin-Madison, Phys.org “Although smartphones and tablets are ubiquitous, many of the companies that make our everyday consumer products still rely on paper trails and manually updated spreadsheets to keep track of their production processes and delivery schedules,” says Leyuan Shi, a professor of industrial and systems engineering at the University of Wisconsin-Madison. That’s what she hopes to change with a research idea she first published almost two decades ago. During the past 16 years, Shi has visited more than 400 manufacturing companies in the United States, China, Europe, and Japan to personally observe their production processes. “And I have used that insight to develop tools that can make these processes run much more smoothly,” she says. These tools are based on the notion of a “digital twin,” or a computer representation of physical assets (machines and people) and processes that helps managers better operate the systems that connect them. Take, for example, a car manufacturing company with 15 different suppliers, each of which delivers a specific car part. As these parts arrive at the company, they are assembled by people who work in different departments, such as sheet metal cutting, heat treatment, welding, painting and so forth. The overall goal of this manufacturing system is to fill a set number of vehicle sales orders. That’s a classic example of a supply chain: a set of processes that link raw source materials to final consumer products. A company’s goal for making supply chain manufacturing more efficient might include decreasing production downtime due to delivery delays for required parts, and better adjusting to unpredictable events, such as rush orders, machine breakdowns, or defective parts. The technology Shi has developed helps managers meet these goals. With a database system, user software and equipment sensors, it creates a digital twin of what is physically happening at the supply facilities and shop floors. Managers can use that digital representation to visually track the global production progress in real time and adjust workflows as needed. The tool provides continuously updated start times for each assembly stage and constantly refined delivery times for the customers who ordered the cars. “That’s what we mean by smart manufacturing,” Shi says. The technology...

The Surprising Key To Keeping The U.S. Expansion Going…

“The Surprising Key To Keeping The U.S. Expansion Going: Manufacturing Innovation” By Marco Annunziata, Forbes  The current U.S. economic expansion is already one of the longest on record—it turned 104 (months) in February. The manufacturing sector holds the key to making it the longest. Manufacturing is currently seen as unglamorous, unloved, needing protection just to survive. I believe this view is profoundly misguided, and that it is in manufacturing that we will see the most powerful growth-enhancing technological transformation ahead. The U.S. economy has picked up speed, and the global economy with it. The IMF recently noted that we are enjoying the most broad-based synchronized upswing since 2010. The U.S. labor market keeps expanding at a robust pace and has created over 17 million jobs since the recovery started; the unemployment rate holds at a very low 4.1%, and strong economic activity keeps attracting more people into the labor force. Wage growth remains muted, however, with average hourly wages increasing at a modest 2.6% pace in the last twelve months. This is a problem. Stronger wage growth would give better support to household consumption, and it would make it easier to reduce income inequalities. Slow wage growth is disappointing, but it should not be too surprising. True, a tighter labor market should boost wages—I believe that it will, and that in the coming months we will see more robust wage pressures. But sustainable strong wage growth depends on productivity. Only when productivity rises at a robust pace can workers enjoy faster wage increases without compromising their firms’ competitiveness and market position. Productivity growth has been dismal of late. In the decade prior to the financial crisis, 1996-2005, U.S. labor productivity rose at an average pace of 3% per year. During the recovery, 2011-2017, it averaged a measly 0.7%–over four times slower. Most other advanced economies have suffered a similar fate. What I find most worrying is that manufacturing sector productivity has suffered an even more severe slowdown: from 4.8% to 0.3% a year. From the early 1990s to the onset of the global financial crisis, productivity growth in manufacturing outpaced the rest of the economy by a significant margin; now it is lagging behind....
