Serious safety concerns with living in same room as PLA 3D Printer?

Fire is the most obvious risk - firmware can now detect some of the more obvious failure modes such as a detached thermistor, but loose or failing connections can still overheat. A smoke alarm is a ...

Would 3d-printed objects outgas in vacuum?

Almost all of the FDM materials outgas even at normal atmospheric pressure, and, in fact, most plastics outgas. Further, FDM and many other printing processes do not guarantee no internal voids - ...

Are 3D prints safe to touch right after printing?

FFF/FDM: Yes FDM/FFF runs by melting a filament and letting it cool again. As soon as the printed parts are cooled down to below 50°C (which is rather quick) handling them is safe. There's no chemical ...

Would 3d-printed objects outgas in vacuum?

This naturally depends on the ultimate pressure you require. I have made a few tests with LEGO pieces (ABS) in vacuum and reached 10-5 mbar without problems. I did not try to go any lower. Otherwise, ...
