## Summary description

Sunlu PLA+ Filament (Black) is a PLA+ 3D printing filament by Sunlu, model PLA+ B, supplied on a 1 kg spool with 1.75 mm diameter. Designed for general-purpose FDM/FFF printing, PLA+ offers improved toughness and reduced brittleness compared to standard PLA. Suitable for prototypes, functional parts and decorative prints that require finer layer bonding and easier post-processing.

## Long description

Sunlu PLA+ Filament (Black) is a 1.75 mm, 1 kg spool of PLA+ 3D printing material designed for general-purpose FDM/FFF printers. The filament targets users who need a balance of aesthetic surface finish and improved mechanical performance compared to standard PLA, delivering higher impact resistance and stable feeding for consistent prints.
Advantages
Sunlu PLA+ offers increased toughness and reduced brittleness compared with ordinary PLA, with improved impact resistance and strong interlayer adhesion. The filament is manufactured to tight diameter tolerances and low shrinkage for stable extrusion, and it is wound evenly on the spool to minimise tangles and feeding issues. These properties contribute to reliable printing, good surface quality and fewer common print problems such as warping or excessive stringing.
Suitable for
Prototypes and functional parts requiring better durability than standard PLA
Decorative prints and models where surface finish and colour depth are important
Everyday FDM/FFF printing on 1.75 mm systems (hobby and professional use)
When it may not be suitable
This PLA+ is not intended for high-temperature applications that require long-term thermal resistance above its Vicat and heat deflection range. It is also not suitable where flexible or rubber-like properties are needed, since PLA+ remains a relatively rigid thermoplastic. For applications demanding extreme elongation or continuous exposure to temperatures above its softening point, alternative materials should be considered.

How to use
Load the 1.75 mm Sunlu PLA+ filament into any compatible FDM/FFF printer and set the nozzle temperature according to the recommended range for your printing speed and model complexity. Use a heated bed if available or apply appropriate adhesion aid; typical bed temperatures are low for PLA but follow your printer and model needs. Adjust retraction, cooling and print speed to reduce stringing and ensure good layer bonding. Allow printed parts to cool before removing them from the build plate to avoid deformation.
What to consider before purchase
Ensure your printer supports 1.75 mm filament
Confirm the recommended temperature range matches your printer’s capabilities
Consider the part’s thermal requirements given the filament’s Vicat and HDT values
Usage recommendations
For reliable results with Sunlu PLA+ Filament (Black), start printing at 200 °C and 60–80 mm/s, enable active part cooling, and fine-tune retraction settings to your hotend to minimise stringing. Use a well-leveled bed and appropriate adhesion (glue stick, blue tape or PEI) for best first-layer results.
