SUNLU PLA+2.0 500g Filament Refill Bundle - Compact 4-Color Pack

In this review of the SUNLU PLA+2.0 500g filament refill bundle the bottom line is simple: this kit is for makers who want a low-waste, no-spool option that still prints reliably for small to medium projects. The reviewer found the bundle delivers the most value through its compact 0.5kg reels that save shelf space and reduce spool waste while offering the improved toughness and high printing speed claims of the PLA+2.0 formulation.

Key Features

• Compact 500g reels: Half-weight reels reduce storage needs and lower plastic spool waste for those printing smaller items.
• Higher toughness: The PLA+2.0 formula offers greater impact strength and toughness than standard PLA, making it better for functional parts.
• Fast printing support: Rated to print up to 300mm/s, the filament keeps smooth flow and consistent extrusion at higher speeds.
• Compatibility: No-spool reels have a reel hole diameter of 82.5mm, which works with many reusable spool setups and is listed as compatible with Bambu Lab AMS style systems.
• Vacuum sealed: Each roll is vacuum packed with a desiccant to limit moisture, reduce bubbles and lower the risk of warping.
• Tight diameter control: The filament is specified at 1.75mm with +/-0.02mm tolerance for stable extrusion and dimensional accuracy.

Who It's For

The bundle is aimed at hobbyists, small workshop users and anyone who prints frequently but prefers not to store full 1kg spools. It is especially useful for printing high-precision models and functional parts where extra toughness matters and for users who want to cut down on unused spool plastic.

Those who should look elsewhere include users who require factory-ready full spools that drop straight into a specific reusable-brand spool without any transfer step, and very large-volume printers that prefer 1kg or larger spools to minimize filament swaps.

Pros & Cons

Pros

• Good filament quality and value for the price, delivering reliable prints for a variety of models.
• Neatly wound and vacuum packed rolls reduce tangles and moisture-related printing issues.
• PLA+2.0 toughness and the ability to print at higher speeds make it suitable for functional parts.
• Compact 0.5kg format saves space and cuts spool waste compared with full spools.

Cons

• Half-size reels do not fit every reusable spool system out of the box, so some users reported fit issues with certain spool holders.
• Winding quality receives mixed feedback from some customers, so occasional attention during setup can be needed.

Our Verdict

The SUNLU 500g PLA+2.0 refill bundle is a practical, budget-friendly option for makers who value reduced spool waste and need tougher-than-PLA material for functional parts. It offers strong dimensional control, vacuum-sealed storage and good print performance, though those needing full 1kg spools or guaranteed fit with a specific reusable spool should check compatibility first.

Frequently Asked Questions

Will these rolls fit my reusable spool?
They are no-spool 500g reels with an 82.5mm hole and often require a detachable spool to transfer filament; verify your spool acceptor supports that hole size.

Can this filament print fast without losing quality?
Yes, the PLA+2.0 is rated for high-speed printing up to 300mm/s while maintaining smooth flow, though settings around 205-220C and proper cooling are recommended.

How is moisture handled?
Each roll is vacuum packed with a desiccant to keep moisture out, reducing bubbles and warping during storage and printing.
