2021 RadLaunch Award Winners

Biomass Derived Chromophores for Radiation Curing

Prof. Jayaraman Sivaguru et al, Bowling Green State University, and Gregory Carroll, Ph.D., NRC Senior Research Associate at the Air Force Research Laboratory

The vibrant colors that enhance Nature’s elegance play a critical role in various chemical and biological processes. Translating these colors, which are dictated by the presence of chromophores, to curing technology is challenging as it requires rational manipulation of excited-state properties.

Jayaraman Sivaguru, Ph.D., the Antonia and Marshall Wilson Professor of Chemistry and Associate Director, Center for Photochemical Sciences, at Bowling Green State University, Ohio, is leading the effort in collaboration with Gregory Carroll, Ph.D., NRC Senior Research Associate at the Air Force Research Laboratory, Sruthy Baburaj, graduate student at Bowling Green and Sheila Asiago, PhD candidate at Bowling Green, as they explore translating biomass derived compounds that can be fine-tuned for radiation curing with both UV and visible light.

The biomass derived compounds are fine-tuned to feature superior photochemical properties than the conventional compounds featuring similar chromophores. Sivaguru's team is working on translating these novel biomass derived compounds as curing systems with high efficiency.

Mighty Buildings

A construction technology company based in Oakland, California, Mighty Buildings is innovating the construction industry by creating beautiful, affordable and sustainable homes using 3D printing, advanced materials and robotics automation. Co-founders Alexey Dubov, Sam Ruben, Slava Solonitsyn and Dmitry Starodubtsev aim to unlock productivity in construction by combining 3D printing and prefab, making construction more sustainable, efficient and affordable.

The company's large-scale 3D printers use a proprietary thermoset composite material that the co-founders invented, Light Stone Material (LSM), that can be 3D printed and that hardens almost immediately thanks to a UV-curing process, while also maintaining cohesion between layers to create a monolithic structure. LSM is four times lighter than concrete, has a high thermal resistance and is watertight, sturdy and fire resistant. This 3D printing technology allows Mighty Buildings to produce modular houses and building components much faster than traditional construction.

Mighty Buildings has a near-zero waste production process, preventing 1,100 - 2,000 kg of CO2 emission per 3D printed home. Committed to achieving Net-Zero by 2028, the company is 22 years ahead of the construction industry. Certified under California’s Factory Built Housing program to build units using 3D printing, the company is the first company to achieve certification under the UL 3401 standard for evaluating building structures and assemblies. Mighty Buildings is backed by notable international and Silicon Valley tech investors, including Khosla Ventures, Zeno Ventures and Y Combinator.

3D Printed Ceramic Resins

Tethon 3D accepts contracted service R&D projects to develop a variety of custom UV curable materials.

Multi-Color Visible Light Additive Manufacturing

Prof. Zachariah Page et al, University of Texas at Austin

A limitation to using high-energy UV/violet light in additive manufacturing is that degradation and attenuation narrow the scope of materials which can be used. While tapping visible light can open the door to more materials - including biological compounds, nanocomposites and materials with multiple structures - the photochemistry required for visible light has had unacceptably slow reaction times.

The research team led by Zachariah A. Page, Assistant Professor in the Department of Chemistry at The University of Texas at Austin, is developing high resolution stereolithographic 3D printing using different colors of low energy visible light to rapidly solidify resins. Key to the research is the team's formulation of panchromatic photopolymer resins.

It has been shown that X-rays generated by high powered electron beam accelerators (already used for decontamination of mail for the US Postal Service since 2002 and for medical device sterilization) can efficiently convert (meth)acrylate formulations commonly used in radiation curable coatings into functional cured matrices for carbon fiber composites, notably as used in automotive components.

Utilizing visible light will enable "spectral control" - the ability to dictate the chemical reaction that occurs by the color of incident light used. This color-specificity provides the foundation for multicolor additive manufacturing (McAM) that will facilitate the fabrication of multi-material objects with unprecedented precision and functionality.

RadTech commends the AF&PA on the release of a new resource for paper-based packaging designers

March 8, 2021:Chevy Chase, MD - Ultraviolet and electron beam (UV+EB) cured inks have been found to cause few problems in the recycling process, according to a recent study by the American Forest & Paper Association (AF&PA). The AF&PA Design Guidance for Recyclability, rated UV+EB inks as not adversely impacting the recyclability of corrugated packaging, bleached paperboard cartons, recycled/unbleached boxboard coated/uncoated, carrier stock cartons unbleached Kraft paperboard, Kraft paper bags, multiwall shipping sacks and molded fiber containers.

“With increased interest among consumer products companies to provide more recyclable packaging for their customers, AF&PA recognized the opportunity to bring clarity to how packaging gets recycled in paper mills and how various non-fiber elements affect the recyclability of paper-based packaging,” says Brian Hawkinson, Executive Director, American Forest & Paper Association. “The objective of the Design Guidance for Paper-based Packaging is to present research-based findings on the effect on recyclability of various non-fiber elements frequently found on paper-based packaging. We believe this guidance will prove useful to members of the paper-based packaging manufacturing supply chain — consumer products companies that desire more recyclable packaging, designers that specify it, and the manufacturers and converters who make it — helping them better achieve their goals.”

SCAQMD Announces New UV/EB BACT Listings

February 19, 2021: Bethesda, Md. - The South Coast Air Quality Management District (SCAQMD) of Southern California has announced new UV/EB technology listings for their Best Available Control Technology Guidelines (BACT). BACT is a pollution control standard mandated by the Clean Air Act that applies to any new or modified source.

The SCAQMD is working to update their BACT listings, with encouragement from RadTech, to better reflect the fast growing pace of UV/EB technology. Rita Loof, RadTech’s, Director of Environmental Affairs, testified at SCAQMD committee hearings, pointing out hat other California air districts such as Bay Area and San Joaquin have updated their guidelines which included super-compliant materials and specifically UV coatings, as alternatives to add-on controls. “Our technology is a pollution prevention technology and should be recognized as an alternative to add-on control devices in the guidelines.”—commented Dr. Loof at a meeting of the District’s Board. Several SCAQMD Board members expressed support for UV/EB technology indicating they believed it is “very clean.” In 2017, the board unanimously supported a motion by Governor appointee Joe Lyou, to adopt the following resolution language:

“BE IT FURTHER RESOLVED that the Board directs AQMD staff to work with industry and other stakeholders on assessing Ultraviolet/ Electron Beam (UV/EB) technology as an alternative to meet Best Available Control Technology.”

The Board’s resolution catalyzed the BACT update efforts and several UV/EB processes were included last year including for a wood coatings operation (cabinets) and also for a flat line glass coating operation. The latter is especially significant as the first BACT for glass coatings, making this a ground breaking listing.
SCAQMD staff has also reported that they recently visited the UV/EB facilities, who reported being extremely happy with the technology. In addition, there is a stringent cost effectiveness for these listings, pointing to the financial benefits of UV/EB.

These BACT decisions do not preclude other processes such as waterborne operations or solvent operations with add-on controls (afterburners) but rather recognizes UV/EB can be viable complaint option. The proposal was finalized on February 8, 2021 when the SCAQMD Board unanimously approved the new BACT listings for UV/EB technology. Specifically, the two categories are:

  • Glass Screen Printing – Flat Glass (Please see Page 7 of staff report)
  • Enclosure with Automated Spray Nozzles for Wood Cabinets (Please see Page 10 of staff report)

The full staff report is at: Determine That Proposed Amendments to BACT Guidelines Are Exempt from CEQA and Amend BACT Guidelines (

RadTech sincerely thanks all of our dedicated members who participated in this effort. Please contact for more information.

3D Printing Committee

November 12, 2020, 2:00 PM - 3:00 PM EST
Opening presentation by Tom McKeag, The Berkeley Center for Green Chemistry

The industrial sector of additive manufacturing (AM) has experienced double-digit growth over the last decade, as the volume and type of material produced using the seven recognized types of 3D printing has expanded. Initially used mainly for prototyping and specialty production, the growth in the field is now dominated by parts manufacture, an exploration of novel materials, and an expansion of user types, including home use.

While this disruptive technology has enabled the saving of energy and materials, as well as the relatively cheap production of complex shapes, current practices also prompt caution. Many of the chemicals used in AM are of concern; for example, typical SLA resin chemicals may cause skin and eye irritation, skin sensitivity, and aquatic toxicity. As such they also represent a potential cost to businesses such as hazardous waste disposal charges.

This talk will describe some of the recent work by the UC Berkeley Center for Green Chemistry to address human and environmental health challenges in the field of additive manufacturing, and how integrating hazard assessment of the materials used into the research, design and development process can lead to innovation and value.
