Nylon cyanide

[Generic Default]

Hi,

A few hours ago I noticed the smell of nylon from my printer (which is 1 meter away from me) and saw smoke coming out of the hotend. It turns out it was well over 400 Celsius for a few minutes because the thermistor connection got loose where I attached two quick disconnects. Don't use cheap quick disconnects on a moving platform with bad wire management.


Anyway, I'm not dead and I didn't get any symptoms of hydrogen cyanide toxicity. This was as close to a worst-case scenario as I've been; I now think that printing with nylon is safer than some people seem to think. The amount of gas given off by a FFF 3d printer is not enough to kill or injure someone so long as they don't sleep in a closet with it overnight. Not that I'd recommend that; let me do the human medical testing for you. Just thought I'd share this since there are a lot of people interested in nylon printing and the safety is a popular subject to discuss.

I bet that was a gas! Seriously, I am glad the smoke was not enough to harm you.
