California Filament Black PETG Filament vs Creality PETG Filament 1.75mm

Both are black 1.75mm PETG in 1kg rolls, and both rate 4.9 stars, but the rating base differs sharply: 347 reviews for California Filament versus 31 for Creality. California Filament gives tighter stated diameter accuracy (+/-0.03mm), a narrower 210-240°C window, a refill option that fits Bambu spools, and a 5kg bulk spool. Creality offers a much wider 190-260°C range, a stated 300 mm/s max speed and 40 MPa tensile strength, which suits tinkerers and mixed printer fleets. Owners of the California roll praise glossy finish, clean winding and outdoor durability, while noting stringing at the sweet spot, stubborn supports and a flimsy spool. Buy California Filament for dialed-in quality and refills; buy Creality for temperature flexibility and brand-matched hardware.

• Choose the California Filament PETG if you want a well-reviewed, tightly toleranced black PETG with a refill option for Bambu spools and a proven record on print farms.
• Choose the Creality PETG if you run Creality printers or want a wide temperature range and high stated speed for tuning across different machines.
