NIOSH Publishes Guidance on Safe Use of 3D Printers for Small Businesses, Libraries, and Schools


The National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention (CDC) has published a new guidance document: “Approaches to safe 3D printing: a guide for makerspace users, schools, libraries, and small businesses.”

In response to concerns by some 3D printer users about potential exposures to ultrafine particles, chemicals, and safety hazards, NIOSH evaluated emissions from different printer and filament combinations operating in both chamber studies and workplace environments to understand the potential health and safety risks. This report summarizes NIOSH’s findings and recommendations for controls to protect workers using 3D printers in makerspaces, schools, libraries, and small businesses.
