I tested graphene-reinforced 3D printing filaments from Prografen: PLA Strong and PETG Strong. These materials promise improved mechanical properties along with reduced wear and friction, thanks to the addition of graphene. But how do they actually perform?
In this video, I run them through a full set of tests, including tensile strength, layer adhesion, shear, torsion, impact, bending, creep, and temperature resistance. I also check friction and wear on both glass and aluminum.
All tests were done using my standard method, so you can compare the results with previous videos.
