PIs need to notify H&S before they buy any new 3D printing equipment as there are a few controls which will need to be in place before they can be used. The main issue is the emission of 3D printing particles which have been shown to be of the size range to potentially enter the airways and lungs and the release of vapours which are known to be hazardous to health. There’s not a whole lot of published research about it yet, but the stuff that has been published seems to suggest that the effects could be really serious, even when using the filaments that have been considered safer. Because of this, the Policy states that all 3D Printers should be enclosed or have local exhaust ventilation. Some printer models are already enclosed and have built in LEV, but some are completely open. The risk assessment prior to use of the printer should identify what level of LEV is needed.

is the UoB printing Policy.
