UV+EB Technology

The capital cost of an electron beam often is cited as a disqualification for consideration. Just this past May at the RadTech event, a presenter excluded EB in a comparison study, before seeking any performance results, because it is an expensive technology – implying that even if it did meet all the tested criteria, it wasn’t worth presenting to...

In three previous issues of UV+EB Technology, we discussed the preparation of nanocomposites made by incorporating carbon nanotubes (CNTs) into UV-polymerizable formulations. 1, 2, 3 The first two of those articles summarized the experimental techniques developed by undergraduate students at the University of Houston-Downtown to determine how well single-walled carbon nanotubes (SWNTs) were dispersed (exfoliated) into an acrylate-functional medium...

This is a new column focused on applications of UV and EB technology in additive manufacturing (AM). Conference reviews, developments in materials, print technologies, post-processing, sustainability and other topics of interest will be reviewed in forthcoming issues. The first subject for the column is a review of the Rapid+TCT Conference, organized by the Society of Manufacturing Engineers (SME), June 25-27,...

By Angelique Runacre, Fujifilm Ink Solutions Group Across all manufacturing sectors, there is a drive for sustainability. In the printing world, inkjet provides huge opportunities for reducing the environmental footprint of printed products throughout the value chain. This paper explores the challenges of formulating a UV-curable inkjet ink with this in mind. Introduction Investments relating to sustainability, net zero and energy efficiency...

By Brian Dillman, IGM Resins Editor’s Note: Part 1 provided an introduction to the materials used in 3D-printing (3DP) formulations and their targeted performance characteristics. It also provided an overview of testing methods utilized. In Part 2, further discussion shows experimental data for the cured properties of formulations based on urethane acrylate oligomers. Tensile mechanical properties, glass transition temperature, and...

At the 2024 RadTech UV+EB Technology & Conference event, held in May in Orlando, Florida, the 2024 Sustainability Award honorees were announced. These companies’ pioneering use of ultraviolet and electron beam (UV/EB) technologies leads the way for sustainable and responsible manufacturing practices. This year’s honorees have demonstrated various benefits, including energy savings, CO2 reductions, minimized water usage and a...

Edited by Dianna Brodine, UV+EB Technology Cast and Cure™ from Breit Technologies, Overland Park, Kansas, is a sustainable, affordable decorative coating process that integrates “casting” and “curing” techniques to create holographic, ultra-high gloss and matte embellishments on a variety of substrates. The Carlson Print Group (CPG) has been a leader in Cast and Cure deployment for many years, producing a...

By Liz Stevens, writer, UV+EB Technology Girl with a Pearl Earring, the painting made by Dutch painter Johannes Vermeer in 1665, is a treasured artwork in the possession of the Mauritshuis Museum, The Hague, Netherlands. The painting, while known the world over, remains a mystery in many respects, even hundreds of years after its creation. In one of the Mauritshuis...
