Beware the toxic chemicals emitted during 3D printer use

Not good.

Home 3D printers – particularly FDM, Makerbot-like devices – are still in their infancy and, as such, are untested when it comes to safety. That’s why some researchers at the Built Environment Research Group at the Illinois Institute of Technology decided to test a popular model for ultrafine particle emissions, a measure of how much junk these things emit while in use.

The result? PLA, a starch-based material, emitted 20 billion particles per minute while ABS, a plastic, emitted 200 billion.
