A recent paper by researchers in the Built Environment Research Group at the Illinois Institute of Technology announces some troubling news for at-home and cubical rapid prototypers; the emission spewing from desktop 3D printers could be releasing harmful nanoparticles.

The researchers measured the aerosol emissions from two commercially available desktop 3D printers to test the detriment that they could cause.

Turns out, it may not be as bad as the abstract of the paper would presume: Ultrafine Particle Emissions from Desktop 3D Printers.
