Biomonitoring of Metal Exposure During Additive Manufacturing (3D Printing).

ABSTRACT:

Background

Additive manufacturing (AM) is a rapidly expanding new technology involving challenges to occupational health. Here, metal exposure in an AM facility with large-scale metallic component production was investigated during two consecutive years with preventive actions in between.

Methods

Gravimetric analyzes measured airborne particle concentrations, and filters were analyzed for metal content. In addition, concentrations of airborne particles <300 nm were investigated. Particles from recycled powder were characterized. Biomonitoring of urine and dermal contamination among AM operators, office personnel, and welders was performed.

Results

Total and inhalable dust levels were almost all below occupational exposure limits, but inductively coupled plasma mass sp
