It would not be possible to conduct such a research without z-temp, since the majority of the tested materials cannot be used with the stock v2 hotend.
I have finished the data analysis of the impact experiments. Cylindrical specimens with a diameter of 20mm and height 30mm were tested against impact loading. The velocity of the drop weight speed maintained constant at 4.6 m/s. In the following diagram the impact energy absorbance, as well as maximum impact force, are presented.
Specimen #, Material
1, CFPLA
2, Longchain
3, PLA/PHA
4, PCPLUS
5, Polymax
6, GWPP
7, Carbonium
8, ZGlass
9, Black Magic
