Filament Material for 3D printers​

It is believed those with respiratory health issue including asthma would be most at risk from filament material for 3D printers​.

Why this substance is hazardous​

At this time there is a concern, but no definitive evidence, that inhaling the fumes and particles from a 3D printer may present a health risk. There has not been sufficient testing done to understand any long term health effect, but it is believed those with respiratory health issue including asthma would be most at risk. ​

Even inert particles can cause both acute and chronic ill-health if they are inhaled into the alveoli of the lungs which can happen if the particle is below 10μm.​


The filament considered the highest risk is those used for FFF (fused filament fabrication) where the object is created by laying down layers of the melted plastic filament.

Recommended Control Measures​

  • Buy suitable equipment. CE marked, enclosed with an emergency shut off​.
  • Location. Well ventilated with space to move around, and if not contained consider local exhaust ventilation (LEV) or an enclosure​.
  • Suitable filament. Deterioration can occur which may raise the hazards. Consideration should be given to storage requirements such as temperature, humidity and light and how often the filament will be used to minimise the risk. ​
  • Procedure. Do not watch the object being created unless the printer is fully enclosed. Consider segregating the printer and workspaces if the printer is going to be continuously or regularly used each day.​ ​
