I was wondering whether there is somewhere a dataset collecting the mechanical properties of different filaments.

Some filament vendors provide some mechanical properties data about their filament, others don’t. On the few comparison I was able to make, I noticed big differences among the same filament type, such as PLA+.

For example, regarding the Flexural Modulus, one brand of PLA+ could report 4175Mpa, while another one reports 1973Mpa. Clearly, the second offers a much higher Elongation at Break. This means that depending on the application, it could make sense to select one brand of filament with respect to another (of the same type).

I would expect this type of mechanical properties to be easy to fetch, but a lot of vendors provide only how accurate the diameter of their filaments is.
