Hi there,
I want to print a bigger object out of PLA. But i read that PLA gets brittle after some years. Is this True?

If yes, could some Layers of lacquer prevent this?

Sure, it's mainly UV rays that destroys our PLA parts. Make sure the paint doesn't dissolve PLA.

PLA is bio plastic, meaning its basically modified corn starch. If its wet or damp it will decompose, slowly smiling smiley

Give PETG a try, its a little more tricky but when you get the hang of it you may never look at PLA again....
