Again, I got to test a sample and have to say that the adhesion between the individual layers seem to be significantly better than with other filaments. As far as I could tell by the test pressure, the filament quality was also here throughout bubble free and uniform diameter. Strong buy recommendation. Noteworthy also attached the fracture behavior. The clip is not broken through, for example, here at the thinner sides, but on the lower side which has not the weak point in that it is connected by superposed layers.
