Manufacturer Offers Design Tips for Custom Springs

May 25, 2017

By Mark Shortt, Design-2-Part Magazine It’s not easy to make a custom spring a reality—that is, to complete the transformation from an idea or concept to a tangible, finished part. Recognizing this, Ritch Froelich set out to help designers understand some of the key considerations required to engineer a custom spring. Froelich is general manager and chief design engineer at Ace Wire Spring & Form Company, Inc., an ISO certified and ITAR registered manufacturer of custom compression springs, extension springs, torsion springs, and wire forms for diverse applications. He wrote a guide, “Proper Requirements of Spring Design,” which Ace Wire Spring has made available to spring designers. The guide covers important factors that designers should consider, for example, when selecting the right material or establishing tolerances for specific applications. Material selection, Froelich said, begins by considering the environment in which the custom spring will perform. Temperature is a key part of that equation. If the part needs to function in temperatures exceeding 650 degrees Fahrenheit, a high-temperature material, such as Inconel, should be specified. “Whereas, if the design requires the spring to work in an ambient temperature environment, perhaps a less costly material, such as oil tempered (spring wire), can be introduced,” Froelich wrote. Another key consideration is whether or not the spring will come into contact with any form of moisture or chemicals, such as chlorine or bleach, according to Froelich. If the part will be used in an outdoor environment that includes exposure to salt water, most professional spring designers would start with T-316 stainless steel, he noted.  “Though there are other, more costly materials on the market, T-316 stainless is highly used in these applications,” he wrote. “If the spring were simply subjected to a high-moisture source, such as tap water, conceivably, a design using T-302 can be implemented.” Other key factors to be considered are cycle life—the amount of cycles that the spring will encounter over its service life—and exactly where the spring will be installed in the application. “If the designer is engineering a spring that works in an engine, and the spring were to be cycled several million times over its lifetime, a material such as chrome silicon...

Google Ventures, BMW, Lowe’s Invest in Desktop Metal

May 9, 2017

Featured on D2Pmagazine.com BURLINGTON, Mass.—Desktop Metal, an emerging startup with a mission to bring metal 3D printing to all design and manufacturing teams, recently announced a Series C investment of $45 million, led by GV (formerly Google Ventures), BMW i Ventures, and Lowe’s Ventures. Desktop Metal will use the funding to continue to develop its technology and scale production as the company prepares for its product launch later this year. The company has raised a total of $97 million in equity funding since its founding in October 2015, according to a press release from Desktop Metal. Previous investors include NEA, Kleiner Perkins Caufield & Byers, Lux Capital, GE Ventures, Saudi Aramco, and 3D printing company Stratasys. Driven by invention, Desktop Metal is committed to accelerating the adoption of metal 3D printing in design and manufacturing through the creation of innovative technology that produces complex parts. “Just as plastic 3D printing paved the way for rapid prototyping, metal 3D printing will make a profound impact on the way companies both prototype and mass produce parts across all major industries,” said Ric Fulop, CEO and co-founder of Desktop Metal, in the release. “We are fortunate to have the backing of a leading group of strategic investors who support both our vision and our technology, and who are pivotal in propelling our company forward as we prepare for our product introduction in 2017.” Desktop Metal has amassed a world-class team of experts in the fields of materials science, engineering, and software, including 75 engineers. Leading the company is Fulop, who was the co-founder of A123 Systems and a general partner at North Bridge, an early investor in leading CAD and 3D printing companies, including MarkForged, OnShape, Proto Labs, and SolidWorks. The leadership team also comprises several MIT professors including Ely Sachs, an early pioneer of 3D printing and the inventor of binder jetting; Chris Schuh, chairman of MIT’s Materials Science and Engineering Department; and professors Yet Ming Chiang, an expert in materials science, and John Hart, who leads the mechano-synthesis lab. Also on the leadership team are Jonah Myerberg, a leader in materials engineering; Rick Chin, one of the early team members of SolidWorks and previously founder...

“Sandia’s Solar Glitter Moves Closer to Market with New Licensing Agreement” Featured on Design-2-Part Magazine ALBUQUERQUE, N.M. —An Albuquerque company founded by a Sandia National Laboratories scientist-turned-entrepreneur has received a license for a “home-grown” technology that could revolutionize the way solar energy is collected and used. The licensing agreement between mPower Technology Inc. and Sandia was signed Jan. 23. The agreement covers microsystems enabled photovoltaics (MEPV), according to a press release from Sandia. “This is an important milestone,” said Murat Okandan, founder and chief executive officer of mPower, in the press release. “It is an extremely exciting time in the solar industry with the upcoming critical, rapid change in the worldwide energy infrastructure. A lot of things are coming together and we’re excited to be part of it.” MEPV uses micro-design and micro-fabrication techniques to make miniature solar cells, also known as “solar glitter.” Dragon SCALEs are small, lightweight, flexible solar cells that fit into and power devices or sensors of any shape or size, including wearable ones. The high-efficiency cells can be integrated into satellites and drones, biomedical and consumer electronics, and can be folded like paper for easy transport. Dragon SCALEs also make possible new shapes and materials and faster, cheaper installation of solar energy systems on buildings, said Okandan. The product offers higher voltage, greater reliability, and lower energy costs than standard silicon photovoltaic (PV) cells, he added. “The key limitation to silicon is that if you bend and flex it, it will crack and shatter,” Okandan said. “Our technology makes it virtually unbreakable, while keeping all the benefits of high efficiency, high reliability silicon PV. It allows us to integrate PV in ways that weren’t possible before, such as in flexible materials, and deploy it faster in lighter-weight, larger-area modules.” Okandan said standard silicon PV operates with low voltage and high current at the cell and module level, which requires more silver or copper and adds cost. MEPV allows high-voltage and low-current configurations with less metal in the system and meshes well with integrated power electronics. “These are basic benefits that apply fundamentally to large-scale solar deployment,” Okandan said. “And the same technology provides key advantages in satellites, drones, and portable...
