UL Chemical Safety and Georgia Tech publish four reports on 3D printers and emissions
The fourth report, “Characterization of Volatile Organic Compound Emissions from Consumer Level Material Extrusion 3D Printers and Their Relationship with Particle Emissions,” has been published by Georgia Institute of Technology (Georgia Tech). The report focuses on a study, completed jointly with UL Chemical Safety, that investigates VOC emissions from multiple 3D printers operating with various filament materials. Specific VOCs are identified, and exposure levels calculated. The relationship between VOCs and particle emissions is also discussed.
In November, UL Chemical Safety and Georgia Tech released the report, “Chemical Composition and Toxicity of Particles Emitted from a Consumer-Level 3D Printer Using Various Materials.” This study reviews the potential toxicity of particles emitted from consumer-level 3D printers using chemical, in vivo and in vitro assessment methodologies.
“Investigating Particle Emissions and Aerosol Dynamics from a Consumer Fused Deposition Modeling 3D Printer with a Lognormal Moment Aerosol Model” was published on April 30 in Aerosol Science and Technology. The published results address the complex processes leading to aerosol formation. Experimental data was combined with a moment lognormal aerosol dynamic model to better understand particle formation and subsequent evolution mechanisms.
On July 6, 2017, the first report in the series, “Characterization of Particle Emissions from Consumer Fused Deposition Modeling 3D Printers,” was published in Aerosol Science and Technology. The report details the sizes, size distributions, and behavior of particle emissions during 3D printer operation. The study also details a methodology for obtaining consistent and accurate particle and chemical measurements.
