Creep test with 3D printed plastic materials: PLA, PETG, ASA, Nylon

Material creep is the tendency of a solid material to deform permanently under the influence of constant mechanical load. In this creep test I am comparing 4 different 3D printing filaments (PLA, PETG, ASA, Nylon) to better understand their behavior under constant load over a longer period of time. I prepared 3 different creep tests, but I am opened for suggestions, how to improve them. One of my next videos will be a comparison of 4 different ABS filaments, to find out which is the best for 3D printed Voron parts.
