6C Pure Black #000000 (On screen it looks blue but its completely black) Your favourite 3D printer manufacturer may have gotten rid of it, but we brought it back. High Flow PETG (Polyethylene Terephthalate Glycol) engineered for high speed printing. The HF formulation melts and flows faster than standard PETG, holding clean walls and strong layer bonding at high volumetric flow rates. You keep everything PETG is known for, strong mechanical strength, superior impact resistance and excellent chemical resistance, while printing considerably faster. Perfect for functional prototypes, mechanical parts and production printing on modern high speed machines. Notes/ Colour Description Pure jet black, consistently black with no blue shades or reflections. Keep under 68c in active applications
