Researchers from the Illinois Institute of Technology and National Institute of Applied Sciences in Lyon, France, published a study this month that found commercially available 3D printers release a high amount of ultrafine particles. UFPs are particles less than 100 nanometers across that can be natural or manmade. UFPs are especially good at working their way into the airways and lungs, where they can be absorbed into the blood stream and cause health problems like lung disease, strokes and asthma over time.
