3KG PLA+ 1.75mm Filament Black - Tough, Fast Printing

In this review the SUNLU 3KG PLA+ 2.0 spool is assessed for makers who need a large-capacity filament that balances strength and speed. The bottom line: this PLA+ spool is aimed at hobbyists and small shops that value consistent winding and resistant material for functional parts, with the single biggest reason to buy being the combination of reduced brittleness and fast printing capability that helps finish large jobs without frequent spool swaps.

Key Features

• Upgrade PLA+ 2.0: The reformulated PLA+ is more resistant to brittleness and cracking, producing stronger printed parts that stand up to handling.
• Supports Fast Printing: The filament melts and flows smoothly to enable printing speeds up to 300mm/s for quicker project turnaround.
• Dimensional Accuracy: Manufactured to +/-0.02mm tolerance, the 1.75mm filament delivers consistent extrusion for reliable layer adhesion and detail.
• Neatly Wound Spool: A consistent, tangle-reducing winding minimizes the risk of snags and clogging during longer prints.
• Vacuum Packaging: Each spool is vacuum sealed to keep the filament moisture-free until first use, preserving print quality.
• Wide Application: Suitable for high-precision models, functional parts, and decorative items where a tougher PLA is preferred.

Who It's For

The SUNLU 3KG PLA+ 1.75mm spool is ideal for makers who run frequent prints and prefer fewer spool changes, including hobbyists, educators, and small fabrication shops printing functional prototypes or larger assemblies. Its toughness and neat winding make it a practical choice when durability and reliable feeding are important.

Those who need highly specialized engineering plastics, very high-temperature performance, or absolute brittleness-free industrial materials should look elsewhere; this filament excels as a versatile PLA+ rather than a substitute for engineering-grade filaments.

Pros & Cons

Pros

• Good balance of toughness and printability for functional parts and models.
• Neatly wound 3KG spool reduces tangles and feeding interruptions during long prints.
• Fast melting and smooth flow support higher print speeds up to 300mm/s when dialed in.
• Vacuum packaging helps prevent moisture-related print issues out of the box.

Cons

• Some users report occasional breakage or tangling, so careful spool handling is still necessary.
• Not a replacement for high-temperature engineering filaments when extreme mechanical properties are required.

Specifications

Our Verdict

The SUNLU 3KG PLA+ 1.75mm spool is a sensible choice for users who want a large-capacity, better-than-standard PLA for faster, more durable prints. It delivers good value with neat winding, vacuum packaging, and reliable dimensional accuracy, making it a practical option for hobbyists and small shops that prioritize throughput and fewer interruptions.

Frequently Asked Questions

Can I use this filament on most 1.75mm FDM printers?
Yes; the 1.75mm diameter and +/-0.02mm tolerance make it compatible with nearly all 1.75mm FDM 3D printers when standard settings are used.

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

How is the spool packaged to prevent moisture?
The spool is vacuum sealed to keep the filament dry until you open it, reducing the need for immediate drying.
