Title: Drillpro Durometer. How Shore Durometer works? What's the hardness of 3D printed plastic materials?. Watch on youtube: https://youtu.be/aPo5CpFAeB8
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.
