CC3D has developed a new 3D printing process to print continuous fiber with UV curable resin; they are reportedly the only company in the world 3D printing continuous fiber with thermoset epoxy and the only company to successfully print continuous fiber into free space. 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.
Seeking to lower their carbon foot print, Pepsico is looking to EB-Flexo Inks as a replacement for their use of solvent based materials for snack food packaging. Technological developments around EB ink chemistry are creating stunning advances in print quality and aesthetics. Pepsico reports the use of EB technology reduces VOC emissions as much as 90%, 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.
Cleveland Steel container 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, with uses ranging from hazardous materials to cosmetics. CSC applies and cures EB and UV directly to steel coil for 5 gallon pail lids and bottoms. Beyond a dramatic reduction in energy requirements, CSC reports that since "EB coatings are 100% 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. According to CSC, traditional thermal systems are massive, and the company just doesn't have the additional space required for that kind of set up."
In a very innovative use of UV curing, 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 WFT to manufacture micro-structures from 200 nanometers up to 150 microns. These unique structures can only be achieved using the latest UV curing and formulating technologies.
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, published in the 1/2016 issue of Science. Potential applications for this novel technology include turbine engine components, hypersonic vehicle structures, MEMS devices, and electronics packaging.
Novagard has developed the first industrial UV LED PSA installation on a coating line. Novagard converted a water based PSA 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, allowing Novagard to pursue new market opportunities.
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. CLIP 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.”
Award is to the City of Cleveland, including Cleveland’s Progressive Field ballpark, home of the major league Cleveland Indians; for their exploration and use of UV curable materials as a contribution to environmental sustainability in Cleveland. The city has found UV technology solutions to long standing issues for protection against corrosion and to provide superior protection for metals, concrete, stones and other substrates in an efficient and fast curing manner.
In recognition of the increasing interest by in the development of sustainable new materials and processes; RadTech now offers an “Accelerator” award to recognize innovative ideas and start-ups. The goal of RadTech is to recognize and publicize the work of new ventures.
RadTech had the pleasure of meeting our first award winners at a recent RadTech meeting in Orlando; the inaugural award winners is Poly6 Technologies.
Poly6 turns citrus rinds into bio-based materials, they call Citrene™. This start-up is introducing clean and sustainable materials for use in performance applications. Citrene™ has gained traction in various industries due to its unique combination of performance, process ability and sustainability advantages, offering Enhanced Performance, Natural Materials, Throughput Benefits, and Low GHG Emissions—all enabled by UV+EB technology.
