Health survey of employees regularly using 3D printers

Area of Science:

• Occupational Health
• Environmental Health
• Industrial Hygiene

Background:

• 3D printing technologies release hazardous ultrafine particles and volatile organic compounds.
• Occupational exposure to these emissions poses potential respiratory health risks for workers.

Purpose of the Study:

• To investigate the association between 3D printing use and adverse health effects in occupational users.
• To identify potential health risks related to 3D printing in various work environments.

Main Methods:

• A preliminary survey was conducted among 46 workers across 17 companies utilizing 3D printing in the Greater Toronto Area.
• Questionnaires collected demographic, occupational, and health information, with data analyzed using chi-square and Fisher's exact tests.

Main Results:

• 59% of surveyed workers reported weekly respiratory symptoms in the past year.
• Working over 40 hours weekly with 3D printers showed a significant association with respiratory diagnoses (e.g., asthma, allergic rhinitis).
• Significant variability in occupational hygiene practices was observed across the surveyed workplaces.

Conclusions:

• The high prevalence of respiratory symptoms indicates a need for further research on the health impacts of 3D printing.
• Findings underscore the importance of evaluating and improving occupational hygiene in 3D printing environments to mitigate worker health risks.
