Drillpro Durometer. How Shore Durometer works? What's the hardness of 3D printed plastic materials?

Let's talk about what is the hardness, how Shore Durometer works and what is the hardness of 3D printed plastic materials. Two Drillpro Shore Durometers (scale Shore A and D) are sent to me by Banggood for the review. But also, in this video I tested the effect of the direction of measuring (layer direction or perpendicular to layers), effect of the temperature to the hardness. In last experiment I tested if Poldi Hammer can be used with 3D printed materials to measure the hardness.
