SUNLU PLA+2.0 500g No-Spool Filament Bundle - High Toughness PLA

In this review of the SUNLU PLA+2.0 500g no-spool filament bundle, the bottom line is simple: it is a practical, space-saving refill option for users who print small to medium parts and want stronger PLA than standard grades. The kit includes four 0.5kg rolls (2kg total) of 1.75 mm grey filament vacuum-sealed with desiccant, and it stands out for its improved toughness and high-speed printing capability. For makers who use reusable spools and want neat winding and consistent diameter control, this refill set delivers reliable prints with fewer material leftovers.

Key Features

• Half-size rolls: Each 500g no-spool reel reduces storage footprint and waste compared with full 1kg spools, making it convenient for smaller projects.
• Improved toughness: PLA+2.0 formulation offers greater impact strength than regular PLA, which helps produce more durable functional parts.
• High speed capable: The material supports fast printing up to 300mm/s while maintaining smooth flow and consistent extrusion for appropriately tuned printers.
• Precision diameter: Filament is manufactured to a tight 1.75 mm diameter tolerance of +/-0.02 mm to reduce extrusion variance and improve layer consistency.
• Vacuum packed: Each roll is vacuum-sealed with a desiccant pack to limit moisture uptake, lowering the chance of bubbles, shrinkage, and warping.
• Reusable spool friendly: The reel hole diameter of 82.5 mm fits many detachable spools and is compatible with Bambu Lab AMS setups when transferred to a reusable spool.

Who It's For

This bundle is aimed at hobbyists, prototypers, and small workshops that prefer buying refill rolls to keep a variety of colors and materials on hand without storing large 1kg spools. It is especially useful for those who reuse spools or use an automated material system that accepts no-spool feed with a detachable spool wheel.

Users who rely on a specific branded reusable spool design or expect a direct drop-in replacement for certain spool systems should exercise caution: the half-spool format and hole diameter have drawn complaints about fit with some spools. Large-scale production users who need continuous 1kg spools may prefer full-size reels instead.

Pros & Cons

Pros

• Good filament quality and value for money with improved toughness for functional parts.
• Neatly wound and vacuum-packed rolls reduce tangles and moisture-related print problems.
• High dimensional accuracy and support for fast print speeds when settings are optimized.

Cons

• Half-size no-spool rolls can cause fit or alignment issues with some reusable spool designs and require transferring to a compatible spool.
• Winding quality received mixed feedback from some users, so occasional tangles are possible.

Specifications

Our Verdict

The SUNLU PLA+2.0 500g no-spool bundle is a sensible buy for makers who want a tougher PLA that prints cleanly at high speeds and saves storage space. It represents good value when you plan to reuse spools or print varied small projects, though buyers should be prepared to transfer the filament to their preferred reusable spool if needed.

Frequently Asked Questions

Is this filament vacuum sealed?
Yes, each 500g roll is vacuum-packed with a desiccant pack to minimize moisture and protect print quality.

Will these rolls fit my reusable spool directly?
The rolls have an 82.5 mm reel hole and are intended for detachable spools, but some users report fit issues with specific spool designs, so transferring may be required.

What print settings work best?
Recommended settings are a nozzle temperature of 205-220C, bed temperature 50-60C, and print speeds between 100-300 mm/s depending on printer capability.
