SUNLU 3KG PLA+2.0 1.75mm Filament - Tough, Fast Printing

In this review of the SUNLU 3KG PLA+2.0 filament the bottom line is simple: this spool suits makers who want a tougher PLA that prints cleanly at higher speeds. The reviewer found it especially useful for projects requiring dimensional accuracy and faster turnaround, thanks to the filament's +/-0.02mm tolerance and improved flow. Beginners benefit from reliable feeding and vacuum packaging, while experienced users will appreciate the neat winding and compatibility with most 1.75mm FDM machines.

Key Features

• Upgraded PLA+: The PLA+2.0 formulation is more resistant to brittleness and cracking, which makes finished parts stronger for functional use.
• Fast printing: Improved melt and smooth flow let users print at speeds up to 300mm/s for quicker iteration without obvious quality loss.
• Dimensional accuracy: With a tolerance of +/-0.02mm the filament produces consistent layers and fits well for high-precision models.
• Neatly wound spool: The first neatly wound PLA design from the brand reduces tangles and the risk of clogs during long prints.
• Vacuum sealed: Airtight vacuum packaging keeps the filament dry and ready to print out of the box, lowering the chance of moisture-related issues.
• Wide application: Suitable for decorative parts, prototypes, and many functional prints across hobby and light industrial uses.

Who It's For

The SUNLU PLA+2.0 spool is well suited to hobbyists and small workshop users who need a balance of durability and speed; it performs reliably on a broad range of 1.75mm FDM printers and is a good option for those printing functional parts or finely detailed models. Its 3KG capacity is convenient for frequent printing or larger single projects where spool swaps would be disruptive.

Users who require exotic mechanical properties, high-temperature materials, or strict engineering-grade filament should look elsewhere, as this product is an enhanced PLA rather than a specialized engineering polymer. Also, anyone using printers tuned only for very slow, ultra-high-detail work may not need the speed advantages.

Pros & Cons

Pros

• Good overall strength and reduced brittleness compared with standard PLA+ formulations.
• Prints smoothly at a wide speed range and supports fast printing up to the stated 300mm/s on capable machines.
• Neatly wound spool and vacuum packaging reduce tangles and moisture problems out of the box.
• High dimensional accuracy (+/-0.02mm) gives consistent results across printers.

Cons

• Some users report occasional breakage or tangling, so careful spool handling is still recommended.
• Not a replacement for high-temperature engineering filaments when extreme strength or heat resistance is required.

Frequently Asked Questions

Will this filament work on most 1.75mm FDM printers?
Yes, the 1.75mm diameter and +/-0.02mm tolerance make it compatible with nearly all 1.75mm FDM machines.

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

How is the filament packaged?
Spools are vacuum sealed to keep the filament dry and reduce moisture-related print issues.
