Is 3D Fuel’s Pro PCTG a real step up from traditional Pro PETG, or just hype? In this video, I put both filaments through a detailed head-to-head comparison: print quality, shrinkage, mechanical tests (tensile, shear, impact, and more), plus how they behave in real applications like snap-fit buckles. If you’re wondering whether it’s time to upgrade from PETG, this video is for you.
