Hello,
This is James Nordstrom from 3DPrintClean, the product mentioned in the Fabbaloo link. We have come a long way since this article was published, launching a pro line of enclosures and filtration systems, that can be found at 3DPrintClean.com and recently launching a Kickstarter for our new Lightweight enclosures. See:
Our Lightweight enclosure was tested by the Department of Civil, Architectural and Environmental Engineering at the Illinois Institute of Technology, if you are interested in the difference between enclosed and filtered printing, and unenclosed printing, please see: http://3dprintclean.com/scrubber-filtration.htm
The team at IIT has released a second paper entitled "Emissions of Ultrafine Particles and Volatile Organic Compounds from Commercially Available Desktop Three-Dimensional Printers with Multiple Filaments" See: http://pubs.acs.org/doi/pdf/10.1021/acs.est.5b04983
