Creality PETG Filament Refill 1.75mm 4kg (4-Pack) - Hubless Refill

Our review of the Creality PETG Filament Refill focuses on small workshops and makers who use Bambu Lab style reusable spools and need plenty of neutral white filament. The bottom line: this pack delivers high precision 1.75mm PETG with good toughness and consistent color, making it a strong choice for functional prints and prototyping when you want to minimize single-use plastic. The hubless design is the single biggest reason to buy, because it feeds directly onto reusable spools and reduces waste without sacrificing dimensional accuracy.

Key Features

• Hubless design: Fits Bambu Lab reusable spools and compatible metal detaching spools to cut down on landfill spools and simplify spool handling.
• Toughness-enhanced PETG: Balances flexibility and strength for parts that resist cracking and warping better than PLA while remaining easier to print than ABS.
• Dimensional accuracy: 1.75mm diameter with +/- 0.03mm tolerance ensures steady feeding and fewer extrusion anomalies in long prints.
• Printing recommendations: Works best at 220-250C nozzle temperature with a 70-80C bed to improve adhesion and layer bonding for functional parts.
• Moisture-controlled packaging: Vacuum sealed and dried to reduce bubbles and nozzle clogs caused by humidity during storage.
• Neat winding: Mechanically wound to reduce tangles and line snaps in most reels, improving reliability for continuous printing jobs.

Who It's For

This refill set is aimed at hobbyists, small shops and educators who already use Bambu Lab A1 family printers (A1, A1 Mini, X1 series, P1 series) or compatible spool systems and want the convenience of hubless filament that mounts directly to reusable spools. It is particularly useful for projects requiring toughness, such as functional brackets, housings or outdoor parts that need better impact resistance than PLA.

Users who rely on other reusable spool standards should verify compatibility first, since fit can be mixed between spool makers. Those needing specialty colors, flexible materials, or filaments for extremely high-temperature applications should look elsewhere; this product is focused on general-purpose PETG in white with environmental benefits from a hubless format.

Pros & Cons

Pros

• Consistent color and filament quality that produces reliable print results for functional parts.
• High dimensional precision (1.75mm +/- 0.03mm) for smooth feeding and steady extrusion.
• Hubless format reduces single-use plastic spools and pairs well with Bambu Lab and Marswork spool systems.
• Vacuum sealed and dried to minimize clogs and bubbles from moisture.

Cons

• Winding quality can be inconsistent for some reels, and a small number of users report tangles or brittle sections on occasion.
• Fit is mixed across reusable spool brands, so it may not work with every third-party reusable spool without verification.

Our Verdict

The Creality PETG hubless refill is a practical, value-oriented option for users invested in reusable spool ecosystems who need toughness and consistent dimensional accuracy. It delivers reliable print quality and reduces spool waste, though buyers should be aware of occasional winding issues and confirm spool compatibility with non-Bambu systems. Overall, it represents good value for functional PETG prints when environmental impact and feed reliability matter.

Frequently Asked Questions

Will this filament fit my Bambu Lab printer?
Yes, it is designed to pair with Bambu Lab A1/A1 Mini/X1/X1C/X1E/P1/P1P/P1S models and similar reusable spools.

What print temperatures should I use?
Use a nozzle temperature between 220-250C and a bed temperature of 70-80C for best adhesion and layer bonding.

Is the filament ready to print out of the package?
Yes, the filament ships vacuum sealed and dried to reduce moisture; allow it to reach room temperature before loading for best results.
