Topic:

3D printing, is it safe? Updates and new findings on 3D printer emissions

3D printing is found to emit particles and volatile organic compounds (VOCs) that can deteriorate indoor air quality and are known to have adverse health effects, as previously presented. This talk will focus on particle and VOC emissions from newer 3D printing technologies and print materials, including consumer level fused filament fabrication 3D printing with various thermoplastics and those with additives of coloring dyes, metals, flame retardants, and desktop vat photopolymerization 3D printing with resins. Emission levels of particles and VOCs from various 3D printers and print materials are measured using a standardized test method in a controlled environmental chamber, and emissions are characterized depending on printer type, print material type and specific feedstock additives, and post-processing methods. Recent data trends, approaches to toxicity assessment assays, and direct filtration effectiveness will be presented.
