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 ...

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 ...

Is there proof that 3D printer made nanoparticles are dangerous?

At the time of this writing (March 2019), I don't think theres any study on the health effects of nanoparticles emmitted by 3D Printers. The general consensus seems to be right now that those ...

Should I consider health impact of ABS or PLA when printing cookie cutter?

If it's one-time-use, both ABS and PLA are perfectly safe for use as a cookie cutter. The "food safety" of 3D printed parts is fairly controversial. In fact, whether any particular material is ...

What are the safest temperatures to heat different filaments to?

Polycarbonate is heat-resistant up to ~120C. Above this temperature it will gradually become flexible and may irreversibly bend. It will not generate any toxic fumes all the way up to ignition ...

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, ...

Printing dental temporary crowns

You ask about "filament", so I assume you expect fused-filament technologies. These are however not accurate enough, besides being prone to gaps and crevices which are problematic in crowns. ...

Is the first layer safe to touch after printing with heated bed adhesive (PrimaFix)?

This is a general purpose catch all warning that some people with sensitive skin might have a rash like reaction, and you should never put these things in your mouth or eyes anyway. It just means that ...

Would 3d-printed objects outgas in vacuum?

At work, I put a 3d ABS part printed via 3d hubs (5*20*30), in the chamber at 1 mbar. No signs of breakage what so ever. No signs of sudden leaks. Going anywhere below 1mbar, i.e., to 10^-infinity ...

What are some good safety tips for a 3D printing beginner?

Check where the moving cables (especially for the heaters) are bending. The bending radiuses should be as wide as possible and connections or soldering points should never see any direct force from ...

Is there proof that 3D printer made nanoparticles are dangerous?

Perhaps FDM 3D printing does emit nanoparticles during the process of printing, but the syllogism does not prove it or even suggest it. Parenthetically, your headline is not actually addressed by ...
