A.Over the past few years, 3D printing (also known as additive manufacturing) has increasingly been a topic of discussion. It’s not hard to see why, as technological advances in hardware, process, software and, of course, materials have caused manufacturers to take notice. Moreover, it’s been the applications of those technologies that have really caught the eye, especially as … [Read more...] about Q. How can new UV-cured chemistries and materials enable expanded applications in 3D printing?
Lumii Sparks Evolution of Printing Technology
By Nancy Cates, contributing editor UV+EB Technology Lumii, a 3-going-on-20-year-old company based in Boston, Massachusetts, was named as one of the winners of RadTech’s Emerging Technology Award this year for bringing evolutionary innovation to the traditional technology of the printing press.

Q. Why is there no ‘standard unit’ similar to lighting products for the radiant output of UV lamps?
A. The visible portion of the output (luminous flux) of lamps used for illumination is expressed in lumens, a measure of the total quantity of visible light emitted by a source. This is possible because the output is measured only in the wavelength response range of the human eye. This response is defined as the photopic luminosity function (Figure 1). Illuminance is the … [Read more...] about Q. Why is there no ‘standard unit’ similar to lighting products for the radiant output of UV lamps?
