NIOSH’s safe-3D-printing guide identifies potential exposure to ultrafine particles and chemicals from 3D printers, including fused-filament and vat-polymerization systems, and summarizes controls for makerspaces, schools, libraries, and small businesses.

3D-printing polymer ultrafine aerosol
Ultrafine particles and related emissions generated during filament-based or resin-based 3D printing.
Airborne form
dust
The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.
