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.

Belt conveyor design program
ABB's new web-based Dodge Passport design tool allows users to select, quote, and order conveyor pulley assemblies complete with shafting and mounted bearings for bulk material-handling applications. Real-time pricing and availability enable customers to make cost-effective selections of readily available components. After selections are complete, Passport's add-to-order capability lets customers seamlessly convert selections into orders via the PT Place e-commerce platform.
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.
Inserts for plastic assemblies provide reusable metal threads
SI inserts from Penn-Engineering permanently install in plastic assemblies to provide durable and reusable metal threads for mating hardware and allow for repeated disassembly and re-attachment whenever required. By promoting quick and easy access to an assembly, SI inserts offer highly practical joining solutions in contrast to fixed and unyielding methods, such as adhesives or rivets. Repeated reuse will not damage the strong metal threads or compromise attachment integrity. Types include brass inserts and lead-free stainless steel and aluminum versions.
New food-grade high-performance PEEK polymers
To help OEMs meet the stringent regulatory and quality demands affecting the food equipment industry, Victrex is introducing a dedicated PEEK food-grade portfolio. Compared to metal components, the new VICTREX FG family of high-performing thermoplastics offers additional benefits in terms of cost effectiveness, productivity, and performance for OEMs -- and the neutral taste expected by consumers. In addition, with the adoption of Industry 4.0 technology, VICTREX PEEK can offer food and beverage manufacturers the opportunity to optimize efficiency and reduce production costs, when compared to the use of metals.
Structural adhesive offers high-temperature stability
DELO MONOPOX HT2860 achieves up to three times the strength at a temperature of 150 C compared to previous product generations. Ideal for bonding magnets in electric motors used in cars, drilling, milling tools, washing machines, as well as in many other applications, this new adhesive has a glass transition temperature (Tg) of 168 C. It achieves a strength of 18 MPa on sand-blasted aluminum at 150 C. This is up to three times higher than standard epoxy resins. The versatile epoxy resin can be heat-cured in an oven for 40 minutes at 150 C or by induction.
Researchers find intrinsic 'fingerprints' that could detect tampered steel parts
David Mascarenas, a research and development engineer at Los Alamos National Laboratory, used Barkhausen noise to find unique-looking "fingerprints" in steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.
Researchers using magnetic signals have found unique "fingerprints" on steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.
"Magnetic signals provide a wide range of possible national security applications," said David Mascareñas, a research and development engineer at Los Alamos National Laboratory and lead author of the study published recently in the journal Smart Materials and Structures. "It's a promising phenomenon that we hope to leverage to uniquely identify different pieces of artillery."
In the research, funded by the U.S Department of State, researchers applied Barkhausen noise, a magnetic phenomenon, to two types of steel -- conventional steel and an abrasive-resistant type of steel used in mining equipment. A sensor measured electromagnetic signals by repeatedly scanning the different kinds of steel over a period of time. Researchers compared the signals from those two sets of scanned images and found signatures that were instrinsic to each type of steel.
The variations that occur from the production of various kinds of steel are reflected as distinct fingerprints. "They seem to be repeatable," said Mascareñas.
That intrinsic signature could help to discover counterfeit or low-grade steel parts in construction by looking for differences in the electromagnetic signatures. "It could also help solve that big problem in that industry," said Mascareñas.
Future research could involve studying other types of steel and developing a handheld sensor for treaty verification.
