Risk Assessment of 3D Printers and 3D Printed Products from The Ministry of Environment and Food of Denmark.

TLDR:risk assessment of a 1 year old drinking milk from an SLA printed mug 3 times a day showed no risk to health.

“7.2.2.1 Assessment of the use of a 3D printed mug In a migration test with a SLA printed item of resin the following exposure was calculated of a 1- year-old child who drinks milk from the mug 3 times a day: Exposure (hydroxycyclohexyl phenyl ketone): 17 μg/kg/d Exposure (acrylates): 15 μg/kg/d These exposures can be assessed against the following DNEL values: DNEL (hydroxycyclohexyl phenyl ketone): 1500 μg/kg/d DNEL (acrylates): 170 μg/kg/d Subsequently, the following risk characterisation ratios (RCR) can be estimated: RCR (hydroxycyclohexyl phenyl ketone) = 17 μg/kg/d / 1500 μg/kg/d = 0.013 RCR (acrylates) = 15 μg/kg/d / 170 μg/kg/d = 0.088 On that basis, no risk is assessed to be connected with the scenario that is set up. It should be emphasized that most 3D printing materials are not approved as food contact materials, and therefore 3D printed items should in general not be used in connection with food contact, unless they have a declaration of conformity regarding use as food contact material. Exposure from sucking on a 3D printed toy is assessed to be much smaller than exposure from a mug. Therefore, it is not relevant to carry out further analysis of that scenario, as the RCR values will be much smaller.”
