Fused filament fabrication (FFF) 3D printers are increasingly a common sight in machine shops and other manufacturing facilities. Read on for guidelines on how to install and operate these printers while avoiding emissions exposure.

When I began reporting on additive manufacturing (AM) just five years ago, I quickly learned about the dangers of metal 3D printing, from the combustible materials to the risks from inert gas leakages. Working with powdered metal is no joke, which is why operators are often pictured in full PPE including respirator, fire-resistant jacket and nitrile gloves.

If you ask one of these folks about safety, they’ll likely point out facility features like specialized fire extinguishers, spark-resistant flooring and air quality monitoring systems. There’s a considerable and widely recognized ecosystem of training and equipment needed to run these machines.
