In this video we perform strength testing of two kinds of samples produced of almost all general purpose polymers available on the market in filament form. The testing is performed following the standard methodology on a well-proved mechanical testing machine with a three-point bending method. Samples of the first kind (the horizontally printed ones) allow to assess material strength, while those of the second type (printed vertically) to assess the interlayer bonding strength which in turn significantly determines the strength of a sample manufactured on a FFF 3D printer.
