Home 3D Printers Emit Some Nasty Stuff, Researchers Find

I think it is always better to ensure that any technology we are ‘deploying’ is tried, tested and certified safe enough for our use.

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. This is similar in scale to using a gas stove, lighting a cigarette, or burning a scented candle. In short, it’s a significant bit of potential pollution in an unfiltered environment but it’s nothing we don’t do to ourselves on a daily basis already.

The study didn’t take into account what materials were being expelled, which makes it a bit more troubling. For example, according to PhysOrg, ABS…
