New 'breathable' rupture disk tech provides overpressure and vacuum relief

To increase equipment safety and reliability, a new rupture disk technology activates at a set burst pressure, but it can also "breathe" to relieve minor pressure fluctuations. The patent-pending, dual-function device from BS&B Safety Systems is ideal for use on low-pressure vessels that are susceptible to ambient temperature changes.

Engineer's Toolbox: 9 considerations for specifying a slewing ring bearing

In applications that require a bearing to support a structure while it rotates (e.g., cranes, radar, tank turrets), premature bearing failure can put people and equipment at risk. While slewing ring bearings have proven themselves countless times in such applications, designers must consider many factors when specifying them. According to engineers at Kaydon, the bearing's support structure, mounting (including bolt strength, tensioning, and hole patterns), installation, and even storage are all factors in a bearing's success or failure.

What are carbon composite bellows springs?

The Carbon Composite Bellows Spring (CCBS) from MW Components is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace coil springs or metallic Belleville disc springs. A functional spring is made from several individual elements paired and joined to make a stack. The stack spring rate is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, and high-performance activities.

Conductive Brush Ring overcomes current leakage in EV powertrains

SKF's new Conductive Brush Ring paves the way to greater reliability and longer life in high-performance electric vehicle powertrain systems. Using pure carbon fiber bristles, it provides a reliable electrical connection between an EV eAxle rotor shaft and its housing. When used in combination with SKF Hybrid ceramic ball bearings, it helps to alleviate parasitic current effects that can lead to premature failure in bearings and other components. Available in different configurations for wet (oil-lubricated) motor designs -- and soon for dry (sealed) applications.

One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

Why hybrid bearings are becoming the new industry standard

A combination of steel outer and inner rings with ceramic balls or rollers is giving hybrid bearings unique properties, making them suitable for use in a wide range of modern applications. SKF hybrid bearings make use of silicon nitride (twice as hard as bearing steel) rolling elements and are available as ball bearings, cylindrical roller bearings, and in custom designs. From electric erosion prevention to friction reduction and extended maintenance intervals, learn all about next-gen hybrid bearings.

Stratasys to combine with Desktop Metal to create 3D-printing powerhouse

Stratasys and Desktop Metal announced May 25, 2023, that they have entered into a definitive agreement to combine the two companies in an all-stock transaction valued at approximately $1.8 billion.

The transaction unites the polymer strengths of Stratasys with the complementary industrial mass-production leadership of Desktop Metal's brands, creating an additive manufacturing company that is expected to be well positioned to serve the evolving needs of customers in manufacturing.

The transaction establishes a uniquely scaled additive manufacturing company that is expected to be one of the largest companies in the industry, targeting $1.1 billion in 2025 revenue. In addition, there are significant opportunities as additive manufacturing increases its offerings in mass production, with expected industry growth to more than $100 billion by 2032.

Bringing together Stratasys' and Desktop Metal's additive manufacturing platform offerings, the combined company will have a broad product portfolio and attractive positions across multiple additive manufacturing technologies and solutions. Upon close, more than 50% of pro forma combined company revenue is expected to be derived from end-use-parts manufacturing and mass production, one of the fastest growing segments in additive manufacturing. The combined company is expected to offer customers end-to-end solutions from designing, prototyping, and tooling to mass production and aftermarket operations across the entire manufacturing lifecycle.

The combined company is also expected to have superior global go-to-market capabilities with enhanced market access for recognizable brands, backed up by premier customer support capabilities. With more than 27,000 industrial customers, the combined company will have a large customer base across industries, materials, and applications to drive significant recurring revenue from consumables.

In addition, the transaction brings together complementary IP portfolios with more than 3,400 patents and pending patent applications. Together, Stratasys and Desktop Metal have invested over $500 million in R&D over the last four fiscal years. In addition, the combined company will have one of the largest R&D and engineering teams in the industry with over 800 scientists and engineers focused on driving innovation across a differentiated materials library.

Under the terms of the agreement, which has been unanimously approved by the Boards of Directors of both companies, Desktop Metal stockholders will receive 0.123 ordinary shares of Stratasys for each share of Desktop Metal Class A common stock. This represents a value of approximately $1.88 per share of Desktop Metal Class A common stock based on the closing price of a Stratasys ordinary share of $15.26 on May 23, 2023. Following the closing of the transaction, which is expected to occur in the fourth quarter of 2023, existing Stratasys shareholders will own approximately 59% of the combined company, and legacy Desktop Metal stockholders will own approximately 41% of the combined company, in each case, on a fully diluted basis.

"The combination of these two great companies marks a turning point in driving the next phase of additive manufacturing for mass production," said Ric Fulop, co-founder, chairman, and CEO of Desktop Metal.

Following the close of the transaction, Dr. Yoav Zeif, currently the CEO of Stratasys, will lead the combined company as Chief Executive Officer together with Fulop as Chairman of the Board. Upon completion of the transaction, the combined company's Board of Directors will be comprised of 11 members, five of whom will be selected by Stratasys, and five of whom will be selected by Desktop Metal, plus Dr. Zeif as CEO. Stratasys Chairman Dov Ofer will serve as lead independent director of the combined company.

And in another update ... Stratasys announced on June 30, 2023, that it has received an unsolicited non-binding indicative proposal from 3D Systems to acquire Stratasys for $7.50 in cash and 1.2507 newly issued shares of common stock of 3D Systems per ordinary share of Stratasys. We'll see what happens. Obviously, lots of movement in the additive manufacturing space.
