Which are 5 toughest filaments I ever tested? #shorts

Video Description

I've tested over 200 filaments, and only a few survived my DIY impact tester with a 0.5 kg hammer. So I upgraded—now I'm testing with a larger hammer capable of measuring up to 5.5 joules of breaking energy. Let's see what these materials are really made of!
