3D Printer Filament Sunlu PLA+ 2.0 (Black) — PLA+ polymer for FDM printing

Sunlu PLA+ 2.0 is a black PLA+ filament for FDM 3D printers offering improved flow and dimensional stability compared with standard PLA. With a 1.75 mm diameter and ±0.02 mm tolerance, the material is formulated to reduce extrusion issues and warping while providing consistent layer adhesion for prototypes, models and household parts.

Advantages

Compared with standard PLA, Sunlu PLA+ 2.0 delivers up to 1.5× greater flow for a steadier feed and fewer nozzle clogs. The filament combines PLA ease-of-use with enhanced durability similar to Easy ABS, providing higher crack resistance and longer-lasting prints. It supports high printing speeds while maintaining quality thanks to stable material feed and low warping tendency.

Suitable for

• General-purpose prototyping and concept models
• Functional parts and household items requiring improved durability
• High-speed printing where stable extrusion is needed (up to 300 mm/s)
• Workshops and small-batch production with mixed-brand FDM printers

When it may not be suitable

Sunlu PLA+ 2.0 is not intended for high-temperature applications where continuous exposure above the material's heat deflection temperature is expected; parts used near or above ~53–54 °C may deform. It is also not a substitute for engineering-grade plastics when extreme mechanical or thermal performance is required.

How to use

Load the filament into a compatible FDM 3D printer designed for 1.75 mm filament. Use typical PLA+ printing temperatures near the material melting point and adjust nozzle and bed settings according to your printer and model geometry. The filament supports high-speed printing up to 300 mm/s; however, verify extrusion stability and layer adhesion at increased speeds and fine-tune retraction and cooling settings to avoid stringing or surface defects.

What to consider before purchase

• Ensure your printer accepts 1.75 mm filament with ±0.02 mm tolerance
• Consider the part’s operating temperature relative to the material’s Vicat/HDT (~54 °C)
• Verify spool moisture control or use a filament dryer if the environment is humid
• Confirm compatibility with your slicer profiles and intended printing speeds

Usage recommendations

For best results, store the filament dry, print initial calibration cubes to set extrusion multiplier and temperature, and start with moderate speeds before increasing toward 300 mm/s while monitoring print quality.
