Summary of time-varying UFP emission rates estimated for
16 3D printer and filament combinations. Each data point represents
data from 1 min intervals, and the combination of data points
represents the entire printing period (typically between 2.5 and 4 h).
Boxes show the 25th and 75th percentile values with the 50th
percentile (median) in between. Whiskers represent upper and lower
adjacent values, and circles represent outliers beyond those values.
