Measuring and controlling emissions from polymer filament desktop 3D printers

Affordable desktop 3D printers are being widely used in businesses, schools and colleges. Some of these printers use filaments to deposit polymer through a heated nozzle to build three dimensional objects. This type of desktop printer is generally unenclosed and some published studies have raised concerns that they may release potentially harmful fumes and particles. The scientific evidence base on exposures and potential health endpoints is being developed internationally.

This report describes initial research in a laboratory setting to a) measure emissions of particulates and volatile organic compounds from desktop 3D printers and b) investigate the effectiveness of control measures to reduce these printer emissions. Two common filament materials were investigated: polylactic acid (PLA) which is generally used in schools, and acrylonitrile butadiene styrene (ABS).
