Key Points

Particle emissions from 3D printer filaments vary widely, impacting air quality significantly.
Emissions were tested from seventeen filament types, revealing the potential release of toxic compounds.
Assessment of filament types showed varied particle size distributions, affecting exposure risks.
Results may enable better regulations on filament usage to improve indoor air quality.
