Polysmooth filament doesn’t like water, changes color

[bhotting]

Hi,

I put a polished 3d printed part in a glass of cold water and it loses/changes color.
The filament is black but changes to mid grey in water.

WoW!
Did u tell polymakr?

[bhotting]

yes they are looking into it.

i repeated the test with 2 parts, one polished the other not. both polysmooth filament
only the polished version changes from black to grey.

now that's quite interesting!

I knew the polishing affected the structure....but the color!? thats quite weird!


did both of your nebulizers work fine?

[bhotting]

the first one worked so didn't try the 2th

it can be me but i have the idea that i can also smell a light alcohol odor when the polished sample is in the water as if the alcohol absorbed by the part some way get released...
i'm not a chemist so no idea what is happening, up to polysmooth to find out...

Bottom line, its not water proof, don't use it outdoor or in the bathroom ;-)
