Description:Fused filament fabrication "3-dimensional (3-D)" printing has expanded beyond the workplace to 3-D printers and pens for use by children as toys to create objects.| Emissions from two brands of toy 3-D pens and one brand of toy 3-D printer were characterized in a 0.6 m| chamber (particle number, size, elemental composition; concentrations of individual and total volatile organic compounds (TVOC)). The effects of print parameters on these emission metrics were evaluated using mixed-effects models. Emissions data were used to model particle lung deposition and TVOC exposure potential.| Geometric mean particle yields (10|-10| particles/g printed) and sizes (30-300 nm) and TVOC yields (
