Cool Tools: World's darkest spray paint

A whole range of products can now take advantage of the world's blackest coating, Vantablack, thanks to the development of a new spray version called Vantablack S-VIS. It is easily applied at large scale to virtually any surface. Vantablack's carbon nanotube matrix structure absorbs virtually all (99.8 percent) incident light, enabling precision optical systems to be optimized. The material's developer, UK-based Surrey NanoSystems, has mimicked the performance of its original Vantablack with this new version that can be sprayed onto objects, rather than deposited using a chemical vapor deposition (CVD) process.

New e-chain features injection-molded contact points to reduce energy-line failure due to freezing

In order to prevent freezing of an energy supply, for example on inclined lifts, the motion plastics specialist igus has developed a new e-chain called "ice-chain." With injection-molded raised contact points, the chance of freezing is significantly reduced along with the costs of downtime and maintenance. This solution can be used in applications down to -40 F. The ice-chain is also available as a complete system equipped with pre-harnessed cables that can be quickly installed and connected.

When should you 3D print jigs and fixtures?

Jigs and fixtures are typically machined, but industrial 3D printing can often be used as a complement or alternative to machining. Designing irregular or complex shapes? Need smaller-than-usual tooling? Building components that are difficult or impossible to machine? If so, additive manufacturing is probably a good fit for your jigs, fixtures, and other tooling needs.

Cool Tools: Desktop full-color 3D printer

The all-new XRIZE desktop industrial 3D printer enables users to manufacture functional polymer and composite parts in full color. And since RIZE's intelligent and innovative solutions focus on the user as much as the machine, XRIZE is easy to use, safe, and enables markup to provide much-desired IP security, traceability, and branding. This machine requires minimal pre-processing, post-processing, and material management. It uses a patented Augmented Deposition process by extruding an engineering-grade thermoplastic and simultaneously jetting C-M-Y-K inks through industrial printheads to achieve the full-color part. Build volume is 12 x 8 x 8 in. (310 x 200 x 200 mm). New carbon fiber materials also available.

Experts answer questions about retaining rings and wave springs

Every year, hundreds of technical questions are submitted through Smalley's "Ask the Expert" page. The company's team of engineering experts answers the questions directly, but they also post them in a blog for sharing. This selection addresses some commonly asked questions about retaining rings and wave springs. Very useful info.

Lube nozzles oil the wheels of aviation gearboxes

Gearboxes used in aviation and other similar demanding applications are specially designed, held to tight tolerances, and require precise and reliable lubrication. This is in contrast to how gearboxes in heavier, more industrial applications tend to be immersed in lubricant without the need for targeted lubrication. The delivery of precise, highly accurate (and in some cases screened lubricants) is usually provided by lube nozzles. The Lee Company, with over 70 years of experience in precision fluid control, is able to offer special nozzle designs to meet most requirements. Safety screens can be added for additional protection.

Tech Tip: Why use flame-resistant adhesives?

Learn about the benefits of flame-retardant adhesive and potting systems, including how they mitigate the risks associated with smoke, toxicity, and flames. Several Master Bond epoxies have been formulated to meet the stringent UL94V-0 specification and pass the horizontal/vertical burn test per FAR standard 14 CFR 25.853 (a). These products feature non-halogenated fillers, have low smoke emissions, and are self-extinguishing.

Protect internal threads during paint and powder coating processes

New PEM PreTect thread masking plugs from Penn-Engineering will protect internal threads of self-clinching nuts and standoffs during paint and powder coating processes. The pre-installed silicone masking plugs -- supplied already in place -- have been designed for self-clinching blind standoffs, thru-hole standoffs, and nuts in thread sizes #4-40 to 1/4-20 and M3 to M6. Plugs can be augmented for thru-hole fastener types with a specially engineered stretched polyester film offering thread protection on the side opposite the plug. Plugs and film can be removed easily using a fine tip tool when processes are completed.

New 3M tape tackles high-temp fastening applications

Since 1980, 3M VHB Tapes have opened the door to faster and easier assemblies. Now, the new GPH series from 3M combines the extreme, permanent bonding power and convenience of 3M VHB Tapes with high-temperature resistance. It can withstand operating temperatures up to 450 F, with long-term durability in conditions up to 300 F. Users will experience excellent adhesion to high and medium surface energy materials, as well as coated or painted surfaces. 3M VHB Tapes, including the new GPH series, replace traditional mechanical fasteners, subsequently eliminating processes like drilling, grinding, refinishing, screwing, welding, and associated rework/clean-up.

Top Tech Tip: Balanced retaining rings

Smalley's balanced feature statically balances the retaining ring. A series of slots, opposite the gap end, account for the missing material in the gap. This characteristic is very useful when the balance of the assembly is critical and it is necessary to reduce eccentric loading.

Updated grippers for plastic materials

FIPA has upgraded its proven product line of sprue grippers for handling plastic material. The Series 90, 100, and 130 grippers now bear the red FIPA dot, which makes the gripper components immediately identifiable in installations. The Series 90 grippers reliably grip small sprues due to their high closing force, wide jaw opening, and compact design, while the Series 100 grippers are designed to securely grip medium to large sprues. The Series 130 grippers feature strong gripping force and a wide jaw opening, making them ideal for large sprues. FIPA grippers have a long life cycle due to their high-strength aluminum alloy housing and jaws, with a durable, corrosion-resistant anodized coating. FIPA also offers grippers with and without "part present" monitoring.

New technique provides breakthrough in ceramics 3D-printing technology

Researchers at HRL Laboratories, LLC, have achieved a new milestone in 3D-printing technology by demonstrating an approach to additively manufacture ceramics that overcomes the limits of traditional ceramic processing and enables high-temperature, high-strength ceramic components.

HRL's Senior Chemical Engineer Zak Eckel and Senior Chemist Dr. Chaoyin Zhou invented a resin formulation that can be 3D printed into parts of virtually any shape and size. The printed resin can then be fired, converting it into a high-strength, fully dense ceramic.

The resulting material can withstand ultra-high temperatures in excess of 1,700 C and exhibits strength 10 times higher than similar materials.

Ceramics are much more difficult to process than polymers or metals because they cannot be cast or machined easily. Traditionally, ceramic parts are consolidated from powders by sintering, which introduces porosity and limits both achievable shapes and final strength.

"With our new 3D-printing process, we can take full advantage of the many desirable properties of this silicon oxycarbide ceramic, including high hardness, strength, and temperature capability as well as resistance to abrasion and corrosion," says program manager Dr. Tobias Schaedler.

The novel process and material could be used in a wide range of applications from large components in jet engines and hypersonic vehicles to intricate parts in microelectromechanical (MEMS) systems and electronic device packaging.

The HRL team's research paper, "Additive Manufacturing of Polymer Derived Ceramics," has been published in the Jan. 1, 2016, issue of Science.
