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.

I wouldn't be surprised if prusa has a lab for qa purposes and they used that for the testing. And yeah I totally get it, I'd assume that at least prusament entries are up to date.

On a plus, definitely feel like I see mech props in product info more often, I've been using Canadian Filaments Carbon Capture PETG lately, they give UTS, Tensile Modulus and Impact Strength.

It's strange that they provide that information for the Carbon Capture PETG and they skipped all the remaining filaments, included the standard PETG. Maybe, they just started testing and adding that info to their products.

I am new to the field, so I cannot judge, but I am happy to hear that you noticed an increase in the mech props reporting. Hopefully, that will be the standard.
