This is an electronics housing printed in Innofill FR PLA, and this is what happens after a few years. Note that this is with a heat load of just 4W!

It spontaneously disintegrates. It makes you rethink on the use of PLA in certain applications, flame retardant or not...
In the past I've printed some small housings for electronics. Most hobbyists do, and most of the time we're not considering how flammable (printed) filament can be.
I've gathered a few illustrative videos, as well as a list of materials and possible (Dutch) sources. This may lead to a little investigation into the flammability of filament. I might turn it into a YouTube video, yeah! (Pfffff 🙄)
My Sunlu S1 mods have been partially successful, and I guess I'll have to consider a DIY solution using Peltiers to move to the next level... Though that one is still in the 'idea phase' 😇
Next challenge / experiment: what to do with old filament, and how to make sure it will last longer?
I've compiled some numbers. Make sure to check your filament specifications - do not rely on my data!
The Excel file is here and may be more up-to-date than the table below.
