Technological developments around EB ink chemistry and lacquer formulation paired with the right choices of flexographic equipment and substrates are creating stunning advances in print quality and aesthetics. Pepsico reports the use of EB technology reduces VOC emissions as much as 90 percent, with lower energy consumption when compared to conventional thermal drying. EB is considered food friendly, which enables Pepsi to make attractive, environmentally compliant packaging that is cost neutral when compared to incumbent solvent and thermal drying technologies.

Wavefront

Wavefront makes state-of-the-art holographic films using advanced roll-to-roll continuous UV casting lines to manufacture nano/micro-structure embossed films on a variety of film substrates. This capability allows for the manufacture of microstructures from 200 nanometers up to 150 microns. These unique structures can only be achieved using the latest UV curing and formulating technologies.

Continuous Composites (CC3D)

CC3D has developed a new 3D printing process to print continuous fiber with UV curable resin; it is reportedly the only company in the world that is 3D printing continuous fiber with thermoset epoxy and the only company to successfully print continuous fiber into free space. CC3D has demonstrated 16x and 8x multi-material nozzles printing at once as a seamless path utilizing 6K TOW carbon fiber, and 600 TEX fiberglass. With a focus on functional composites additive manufacturing to scale, CC3D is providing an industrial solution to advanced manufacturing techniques of mid- to large-scale.

HRL Laboratories LLC

The HRL team demonstrated the first-ever UV additive manufacturing of polymer-derived ceramics. By formulating pre-ceramic UV curable polymers, the team at HRL demonstrated the first-ever additive manufacturing of fully dense, binder-less ceramics. The accomplishment was published in the January 2016 issue of Science. These unique pre-ceramic photopolymers can be integrated into commercially available UV SLA or DLP equipment to produce flaw-free, high-strength ceramics with up to 1800 °C operating temperatures. Potential applications for this novel technology include turbine engine components, hypersonic vehicle structures, MEMS devices and electronics packaging.

Cleveland Steel Container

Cleveland Steel Container (CSC) has developed the first commercial in-line EB and UV process for rigid steel coil substrates in the manufacture of steel pails. CSC is the largest steel pail manufacturer in North America. CSC applies and cures EB and UV directly to steel coil for five-gallon pail lids and bottoms. This application is also unique in the use of highly pigmented systems to steel for rigid fabrication. Beyond a dramatic reduction in energy requirements, CSC reports that since "EB coatings are 100-percent solids formulations, it means no loss of evaporated solvent from the applied coating. It also means less coating usage and required storage area compared to solvent systems. EB was not only found to be a more efficient technology, it also contributes significantly to a higher level of workplace comfort. Traditional thermal systems are massive, and the company just doesn't have the additional space required for that kind of setup."

NOVAGARD Solutions

Novagard has developed the first industrial UV LED PSA installation on a coating line. Novagard converted a water-based PSA for its 58" wide PVC foam line to a UV LED curable PSA and is now using it in to produce PVC foam rolls (more commonly known as weather stripping). The system consists of two 62"-wide banks of UV LED curing systems. Conventional UV lamps could not be used as they delivered too much heat to the substrate, causing damage. UV LED was the only viable solution. Going to a UV solution resulted in a superior peel strength, which allowed Novagard to pursue new market opportunities.

Carbon 3D

Carbon’s vision is “a future fabricated with light, where traceable, final-quality parts are produced at scale with CLIP technology.” CLIP (continuous liquid interface production) makes this possible by combining engineering grade materials with exceptional resolution and surface finish. By harnessing light and oxygen to produce objects from a pool of resin, CLIP is a photochemical process that eliminates the shortcomings of conventional 3D printing by more rapidly producing objects. “From everyday products like tennis shoes and electronics, to industrial components, to highly customizable medical devices, CLIP makes it possible for creators to design the parts and products of the future.”

Such ABR resins could be readily formulated in a variety of radiation-cure compositions, such as composites, adhesives, sealants, coatings to provide high performance non-leaching active surface to effectively kill a wide range bacterium with very low loading dose in the compositions without adverse impact on mechanical integrity and to inhibit the formation of such bacteria-based biofilms. Furthermore, it could lead to dramatically ease biofilm removal. This innovation promises to find wide range applications in biomedical and other industries; and has recently been published in ACS Applied Materials and Interfaces.

Eastern Michigan “Collegiate Emerging Technology Award.”

“’Green’ UV-LED Curable Nail Gel Polishes from Bio-Renewable Materials,” are novel polymers that have been synthesized from bio-renewable materials such as plant oils (such as soybean oil, corn oil, canola oil), itaconic acid, gum rosin, and bio-based succinic acid. These bio-based polymers have been suitably functionalized with unsaturated functional groups such that they can polymerize and form a crosslinked network when exposed to UV-LEDs. From Eastern Michigan’s research, bio-based nail products have not been sufficiently explored. And considering the increasing consumption of nail polishes; and the need to keep pace with the bio-based regulations and consumer preferences, they are meeting an unmet opportunity to develop novel sustainable nail gel polishes with considerable bio-renewable content.

Australian inventor Henry Bilinsky has used Shark Skin as a basis for a new drag reduction surface for planes. Currently under test by the US Air Force, this nature based design is looking to save millions of dollars for Military and Commercial Airlines by reducing drag.

"MicroTau is developing a novel method of applying drag-reducing microstructures – called ‘riblets’ – onto the surface of aircraft to reduce fuel consumption. Riblets are microscopic ridges spaced a fraction of the width of a human hair apart. As a rule a smoother surface is more aerodynamic, however these ridges – designed over millions of years of evolution – actually decrease drag when compared to a perfectly smooth surface." MicroTau

This may be able to be used in the marine environment with similar results.
