The Test your print package “PROFESSIONAL PACKAGE” includes the testing of 5 tensile strength and 5 impact strength specimens and the creation of a test report. The STL files for the printing of the test specimens is available under Downloads. There you will also find a test report as a sample.
Tensile strength & Impact strength explained
The “Tensile strength” is a value how much I can pull on the material. 1 MPa corresponds to 1 N/mm² (Force per surface). 1 kg corresponds to 9,81N. The tensile strength specimen has a cross sectional area of 40mm². In other words, a tensile strength for example of 50 MPa means, that a tensile specimen with a cross-section of 40mm² will break at a tensile load of 203,9 kg.
The “Impact strength” is a measure of how well the material can absorb shock and impact energy. kJ / m² (energy per cross-sectional area). An impact strength of 50 kJ / m² corresponds to the energy of a 1 kg heavy weight from a fall height of 20 cm, which is necessary to break a printed sample with a cross section of 40mm².
