Insights Into Emissions and Exposures From Use of Industrial-Scale Additive Manufacturing Machines.

ABSTRACT:

Background

Emerging reports suggest the potential for adverse health effects from exposure to emissions from some additive manufacturing (AM) processes. There is a paucity of real-world data on emissions from AM machines in industrial workplaces and personal exposures among AM operators.

Methods

Airborne particle and organic chemical emissions and personal exposures were characterized using real-time and time-integrated sampling techniques in four manufacturing facilities using industrial-scale material extrusion and material jetting AM processes.

Results

Using a condensation nuclei counter, number-based particle emission rates (ERs) (number/min) from material extrusion AM machines ranged from 4.1 × 10¹⁰ (Ultem filament) to 2.2 × 10¹¹ [acrylonitr
