How are these PLA filaments tested?

Tensile strength

Tensile test specimen, minimal cross section area: 4x4 mm. Specimen is printed in horizontal position with 100% infill but with maximal number of perimeters (or walls or shells in Cura)

Layer adhesion:

Test specimen for layer adhesion is printed in vertical position also with maximal number of perimeters. Minimal cross section area is 4x4 mm.

Impact test

Impact test is based od IZOD impact test with specimen dimensions defined in ISO180 (80x10x4 with 2 mm deep notch)

Shear stress

Two sided shear stress with cross section diameter of 5 mm (x2). This means area of cross section is 39.27 mm2.

Bending test is not prepared yet (it will be based on ISO 178, test specimen: 80x10x4 mm)

Torque test in progress.

Elasticity test specimen design is in progress.

Temperature tower

The temperature tower is downloaded from Thingiverse, designed by gaaZolee (Thing: 2729076). Tower is modified (using provided elements) to get range from 230 to 190 with step of 10°C. It is small and compact object and contains several test patterns like overhangs from 30 to 65 degrees (from vertical angle), bridges from 15 mm - 30 mm, stringing test.
