PLA Plus 2.0 1.75mm 4kg Filament Bundle - High Speed, Low Stringing

In this review the SUNLU PLA Plus 2.0 1.75mm 4kg filament bundle is evaluated as a practical option for hobbyists and makers who want faster, more reliable PLA prints without complex tuning. The main reason to buy is its upgraded PLA+2.0 formula, which promises significantly higher toughness than standard PLA while maintaining optimized melt flow for high speed printing. For users with high-speed printers who need consistent spool compatibility and low moisture issues out of the box, this bundle aims to reduce downtime and deliver predictable print results.

Key Features

• Upgraded PLA+2.0: Offers substantially higher toughness versus standard PLA for parts that resist impact better during handling and post-processing.
• High speed printing: Formulated for speeds from 50 to 600mm/s so prints can be completed faster with reduced stringing on compatible high-speed machines.
• Bambu-compatible spool design: The removable inner core allows quick refills without respooling, simplifying filament swaps and reducing filament handling time.
• Precision diameter: Strict 1.75mm 0.02mm tolerance helps ensure consistent extrusion and dimensional accuracy across layers and large prints.
• Vacuum sealed spools: Each spool arrives vacuum-sealed with a desiccant pack to limit moisture absorption and preserve printability right away.

Who It's For

The bundle is best for hobbyists, makers, and small workshop users who run fast 3D printers and want a filament that handles higher print speeds with fewer clogs and low stringing. It is especially useful for people who appreciate ready-to-print spools that are vacuum-sealed and easy to refill into compatible machines.

Those who require specialty materials like flexible TPU, engineering-grade nylons, or food-safe filaments should look elsewhere, since this product is an upgraded PLA variant designed for general-purpose prints and faster turnaround rather than chemical resistance or flexibility beyond standard PLA+ ranges.

Pros & Cons

Pros

• High toughness compared with standard PLA, which improves part durability during handling.
• Optimized melt flow for high speed printing, helping reduce print time on compatible machines.
• Bambu-compatible removable spool core and vacuum sealing make handling and storage straightforward.
• Consistent diameter tolerance reduces extrusion issues and warping on larger parts.

Cons

• Durability feedback is mixed from users, so extreme mechanical demands may still require a different material.
• This filament is focused on speed and general print quality rather than specialty properties like extreme flexibility or solvent resistance.
