A New Era of 3D Printing

A New Era of 3D Printing

May 16, 2018

By Mark Shortt, Design-2-Part Magazine Adaptive Corporation, Inc. strives to enable innovation by applying technology to streamline business processes, reduce costs, and improve efficiencies throughout the product development lifecycle. Adaptive is a reseller of Markforged 3D Printers, like the Onyx Seriesand Metal X, which are used to make carbon fiber composite and metal printed parts, respectively. Frank Thomas, a metrology and additive manufacturing specialist for Adaptive, has worked with a variety of manufacturing companies in the areas of engineering, metrology, and additive manufacturing, as both an implementation consultant and product specialist. Over the past 10 years, he has focused on connecting engineering and manufacturing, specifically around quality, and now additive manufacturing.  His goal is to help companies better connect the “virtual” to the “physical,” thereby improving their time to market and reducing cost. Thomas said that until fairly recently, additive manufacturing was used most often as a tool to create parts that you could hand to somebody so that they could see it, touch it, and provide some input as to what might need to be changed or modified. But that’s changed in recent years as new materials have been developed that enable printers to make stronger, more durable parts. “Metal printing has always been there, but that has an economic value proposition that’s a bit challenging for it,” he said in an interview. “The ABS and nylon and other plastic 3D printers, up until the last couple of years, weren’t necessarily dimensionally accurate, and then they had challenges creating a part that’s functional. That’s what I think is different about the market today, compared to just, really, a couple of years ago.” Adaptive markets 3D printers that feature dimensional accuracy and the ability to yield a part that is functional, depending on the application. Thomas said that he’s also seeing a lot of interest in metal 3D printing. “Where metal 3D printing comes from is the argon laser based systems,” he told D2P. “The companies that have had applications or use cases for them have made the investments, and they’ve been huge investments. They probably start at half a million dollars and go up, and that doesn’t even count the facility that’s required to be able to...

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...

New 4-D printer could reshape the world we live in

New 4-D printer could reshape the world we live in

Mar 22, 2018

By The American Chemical Society Featured on TechXplore.com A powerful new 4-D printing technique could one day allow manufacturers to produce electronic devices and their wiring in a single process. From moon landings to mobile phones, many of the farfetched visions of science fiction have transformed into reality. In the latest example of this trend, scientists report that they have developed a powerful printer that could streamline the creation of self-assembling structures that can change shape after being exposed to heat and other stimuli. They say this unique technology could accelerate the use of 4-D printing in aerospace, medicine and other industries. The researchers are presenting their work today at the 255th National Meeting & Exposition of the American Chemical Society (ACS). “We are on the cusp of creating a new generation of devices that could vastly expand the practical applications for 3-D and 4-D printing,” H. Jerry Qi, Ph.D., says. “Our prototype printer integrates many features that appear to simplify and expedite the processes used in traditional 3-D printing. As a result, we can use a variety of materials to create hard and soft components at the same time, incorporate conductive wiring directly into shape-changing structures, and ultimately set the stage for the development of a host of 4-D products that could reshape our world.” 4-D printing is an emerging technology that allows 3-D-printed components to change their shape over time after exposure to heat, light, humidity and other environmental triggers. However, 4-D printing remains challenging, in part because it often requires complex and time-consuming post-processing steps to mechanically program each component. In addition, many commercial printers can only print 4-D structures composed of a single material. Last year, Qi and his colleagues at Georgia Institute of Technology, in collaboration with scientists at the Singapore University of Technology and Design, used a composite made from an acrylic and an epoxy along with a commercial printer and a heat source to create 4-D objects, such as a flower that can close its petals or a star that morphs into a dome. These objects transformed shape up to 90 percent faster than previously possible because the scientists incorporated the tedious mechanical programming steps directly into the...

Metal 3D Printing Hits the Big-Time

Mar 14, 2018

By Jeff Reinke, Industrial Equipment News Engineering powerhouse Roush explains their end-product manufacturing strategies after purchasing the largest metal additive manufacturing system of its kind. Livonia, Michigan-based Roush is a full-service product development supplier with over 4,000 employees throughout North America, Europe and Asia. The company is known for its innovative engineering, testing, prototyping and manufacturing services within the mobility, aerospace, defense and theme park industries. Oh, and then there’s Roush Fenway Racing, Roush Performance and Roush Cleantech that develops and manufactures performance vehicles and alternative fuel systems.  So, it’s safe to say that the company knows a thing or two about manufacturing and product development technologies. The company recently invested in the largest powderbed metal additive manufacturing system of its kind –  the Xline 2000R.  Made by Concept Laser, which was acquired by GE Additive in 2016, the machine features a build envelope of 800 x 400 x 500 mm production of parts as large as engine blocks. IEN recently interviewed Roush’s Brandy Badami to get some insight on the machine, how her company utilizes the technology, and the impact additive manufacturing could have on production strategies  Jeff Reinke, IEN editorial director: Could you offer a little background on Roush’s history with additive manufacturing and 3D printing technologies? Brandi Badami, Roush business development manager – additive manufacturing:Roush has over 20 years of experience with 3D printing/additive manufacturing, mainly in plastics/polymers. We started off with stereolithography (SLA), then selective laser sintering (SLS), then polyjet/objet technologies. Roush adopted 3D printing into our everyday practices with product development and rapid prototyping to support our design engineering and tooling groups.  As the technologies and materials advanced, we used additive manufacturing for functional prototypes, end-use components, fixtures, tools and gauges. Now, with the recent investment of new 3D printing technologies and equipment, including fused deposition modeling (FDM) from Stratasys and 3D metal printing (powder bed fusion) machines from EOS and Concept Laser (a GE Additive company), we are able to expand our reach within the aerospace, defense, entertainment and transportation industries. JR: How will the addition of this machine change things on a day-to-day basis? BB: The addition of the Xline 2000R has, and will continue, to open many doors for how...
