In this video, I test Polymaker HT-PLA and HT-PLA-GF, two high-temperature PLA-based filaments that promise excellent mechanical strength and heat resistance—possibly challenging the boundaries of what PLA is known for.

I go through everything from unboxing and filament behavior to detailed mechanical tests like tensile, impact, bending, and creep testing. I also cover annealing, temperature resistance, and layer adhesion to give you a complete overview of how these materials perform.
