I wanted to know, if the Bambulab PLA-CF is stronger than my eSUN PLA+ and my ERYONE PETG filament.

So I created this simple test, where you can see, how much weight the filament can hold before it bends/breaks.

1. Print with 100% infill
2. Clamp the flat side of the test print to you table (exactly to the middle line)
3. Hang a bucket to the other side with the vertical holder
4. Fill the bucket with weight of your choice (I choose 0,5l water bottles)
5. See, when it starts to bend or break

My personal result was: Bambulab PLA-CF is - despite having carbon fibers in the filament - much weaker than PLA+ from eSUN. PETG from ERYONE is about the same as PLA+ from eSUN.

I would be happy to see your results! :)
