New high-performance metals for 3D printing

3D Systems has added two new materials to its materials portfolio. Certified HX is a high-performance nickel alloy that contains a higher percentage of molybdenum (up to 9.5%) vs. other nickel alloys, which enhances strength and resistance to corrosion, creep deformation, cracking, and oxidation in hot-zone environments. Certified CuCr2.4 is a high-strength, corrosion-resistant copper alloy that is significantly stronger than pure copper and easier to process. Both materials are certified for use with the company's DMP Flex 350 and DMP Factory 350 3D printers. Applications include industrial gas turbines, consumer goods, aerospace and defense, and automotive.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted, thereby reducing reaction loads resulting from the misalignment. Ideal for unidirectional continuous movement or rapid bidirectional motion.

Feel the difference: 2-shot injection molded knobs sample pack

In 1979, Rogan was the first knob company to mold a knob utilizing the 2-shot injection molding process, which uses a single plastic molding machine specially made to inject two materials sequentially or one on top of the other. If you've ever used a plastic toothbrush with a colorful rubber grip, it was likely 2-shot injection molded. Create a competitive advantage for your products. You can add markings, custom colors or graphics, and even glow-in-the-dark materials. Request a sample of control knobs or clamping knobs -- or both.

Simplify your designs with slewing ring bearings

According to Kaydon Bearings, "A slewing ring bearing has rolling elements designed to create a reactive moment within the bearing's dimensions envelope to oppose applied (overturning) moment load," so you can use one bearing instead of two, reducing the height requirements, and even improve performance. Slewing ring bearings can also simplify a drive system by utilizing gear teeth on the inner or outer race. Learn all about slewing ring bearings in this informative article.

DENSO reduces component sim time by 80% using Simcenter 3D and NX integrated process

DENSO Corp., the second-largest automotive parts and systems provider in terms of sales in the world, is developing its "NX CAD and Simcenter 3D integrated process" from Siemens that allows analysts to understand the simulation processes, which are repeatable for certain types of components. The DENSO team captures modeling and process best practices and packages these up into simulation templates that are leveraged by designers using NX. This process has led to increased quality, because design problems are identified earlier and can be corrected before the project advances. DENSO estimates the average time for analysis was reduced up to 80% using this integrated process.

Low-friction lightweight thermoplastic composite bearing

Trelleborg Sealing Solutions recently launched its latest lightweight thermoplastic composite bearing, the HiMod Advanced Composite Bearing Plus, which is an enhanced dual-layer bearing with a modified PEEK layer that reduces friction and increases wear performance for use in bearing, wear ring, and bushing applications. These bearings will not seize or gall. Manufactured using Trelleborg's patented Automated Fiber Placement (AFP) technology, a thin, low-friction liner is bonded to the inner diameters and can be added to the outer diameters of the bearing to create a high-quality solution for use in a wide range of industries.

Magnetic couplings 'mechanically isolate' shafts and motor

Magnetic couplings from Miki Pulley are ideal for machine designs involving food, pharma-ceutical, and laboratory applications requiring clean, non-contact connection between motor and shafts. The mechanically isolated magnetic coupling transmits torque through the air. This occurs through both input and output hubs of the coupling, which contain powerful rare-earth magnets. These magnets create a magnetic field that transmits torque through plastic, glass, aluminum, and other minimally ferrous materials without physical engagement. There is no dust, debris, or mechanical wear using this coupling compared to conventional couplings. It can also act as a torque limiter in an over-load event.

DOD investments secured critical beryllium material for James Webb Space Telescope

By Devon Bistarkey, Office of the U.S. Undersecretary of Defense for Acquisition and Sustainment

NASA's James Webb Space Telescope recently captured the highest-resolution image of the universe in infrared that has ever been seen. The historic photos were made possible by the Defense Department's ability to secure strategic and critical materials necessary for the mission.

At the top of that list is the unique element beryllium.

NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb's First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. [Credit: Photo by NASA, ESA, CSA, STScI]

 

 

 

 

Invisible to X-rays and with a stiffness six times greater than steel, beryllium is an element in a class by itself. Due to its unique properties, DOD and the Department of Energy use beryllium in many important technologies, such as missile and weapons defense systems, surveillance satellites, fighter jet optical targeting devices, and much more.

Building a telescope capable of capturing never-before-seen details of entire galaxies required the development of a lightweight, durable material that would maintain a stable shape in extreme conditions during the journey into space. The shift from glass mirrors to beryllium-based mirrors augmented the resolution of the space telescope's captured imagery.

Long before it was launched into space on Dec. 25, 2021, NASA's Marshall Space Flight Center in Huntsville, AL, completed cryogenic tests on six James Webb Space Telescope beryllium mirror segments. The mirrors were subjected to extreme temps dipping to -415 F so engineers could measure how the shape of the mirror changed as it cooled.

"Beryllium is a really good material for that," said Payl Geithner, a deputy project manager for Webb based at Goddard Space Flight Center. "It's really stiff, and once it gets below about negative 300 degrees Fahrenheit, it basically stops shrinking. This is important because Webb, insulated by a sun shield, operates at about 30 kelvins [negative 406 degrees Fahrenheit] and only experiences temperature swings of plus or minus 30 [kelvins], never reaching a temperature that would cause it to expand."

Lee Feinberg, the telescope manager for Webb at Goddard Space Flight Center, said that beryllium is also advantageous because its stiffness makes it better able to withstand the high vibro-acoustic levels experienced during takeoff.

Beryllium, however, is a difficult element to extract, and the DOD has recognized its strategic value for some time. In 2003, Congress directed a study on the domestic beryllium industrial base. The following year, based on the report's results, Congress appropriated $3 million under the Defense Production Act, a Title III program for the preliminary design of a new primary beryllium facility. In total, the DOD has invested $85 million for capital equipment and process efficiencies to ensure domestic availability of high-purity beryllium.

Through this program, Materion Corp. created the first beryllium metal production facility in more than 50 years and refined the process for transforming beryllium ore into the sturdy, lightweight metal required by NASA for the mirrors used on Webb.

The current investment program with Materion Corp., awarded in 2019, is on cost and schedule to deliver facility enhancements by April 2023 and full production capacity by the end of next year.

The DOD has also long been a silent partner of NASA, which was born from the tensions of the Cold War and the space race with the Soviet Union. Since laying the groundwork for the historic moon landing on July 20, 1969, DOD has worked closely on the research and development of technologies in a mutually beneficial relationship with NASA. With inventions like the Hubble and Webb space telescopes, the U.S. has been instrumental in the scientific understanding of the universe.
