Airborne particle emission of a commercial 3D printer: the effect of filament material and printing temperature.

abstract：UNLABELLED:Measurements of combustion product concentrations were taken in 30 homes where unvented gas fireplaces were used. Measurements of CO, CO(2), NO(x), NO(2) , O(2) (depletion), and water vapor were taken at 1-min interval. The analyzers were calibrated with certified calibration gases for each placement and wer...
