3D printers can manufacture three-dimensional objects by building them layer by layer from a digital drawing.
The increased interest is noticeable both in schools and libraries as well as in homes. The problem is, however, that the products printed out do not undergo the same standardized tests as other goods.
"Particles and vapors emitted by the printer can also be harmful to health, and we need to increase awareness of the risks associated with these, particularly to protect children both in school and at home," says Bert-Ove Lund, toxicologist at the Chemicals Inspection Agency in a press release.
The printers have also been shown to emit nanoparticles, which can penetrate deep into the lungs and cause inflammation and tissue damage.
Users of 3D printers are advised to place the printer in a well-ventilated area and preferably near an exhaust vent, and to wait 20 minutes before opening the enclosing hood to avoid emissions in the room. The material used should also be suitable for the intended object.
Furthermore, an enclosed printer with a fan and filter is recommended, which can reduce the amount of hazardous emissions.
