EXTRAORDINARY TOUGHNESS AND STRENGTH: Designed for high-impact projects, 3D-Fuels Pro PCTG filament delivers durability, up to 20x tougher than PETG. Its impressive strength and smooth printability make it ideal for demanding applications that require long-lasting, robust prints. IDEAL FOR METAL HOTENDS: Optimized for all-metal hotends, Pro PCTG requires printing temperatures of 250-270°C and a heated bed at 70-85°C. Its low-warp, minimal shrink properties mean precise, consistent prints every time, with great layer adhesion for reliable results.
