eSun PLA+175B1 3D printing filament, Polylactic Acid plus (PLA+), Black, 1 kg

eSun PLA+175B1 is a 1 kg spool of black Polylactic Acid plus (PLA+) filament designed for FDM/FFF 3D printers. This PLA+ material offers improved toughness and reduced brittleness compared with standard PLA while maintaining easy printability and good dimensional stability. The filament is compatible with printers from any brand and is suitable for a wide range of applications including prototyping, hobby models, and functional parts that require a balance of strength and ease of use.

Advantages

PLA+ combines the user-friendly printing characteristics of standard PLA with enhanced mechanical properties: increased impact resistance, less tendency to crack, and improved interlayer adhesion. The filament prints at typical PLA temperatures and does not require a specialized high-temperature extrusion setup. Its consistent diameter and uniform extrusion help deliver reliable results across different FDM/FFF machines. Black color provides a neutral, finishing appearance for prototypes and end-use parts.

Suitable for

• Rapid prototyping and concept models
• Hobby and decorative models
• Functional parts with moderate mechanical stress
• Detail-oriented prints requiring good surface finish

Key specifications

• Material: Polylactic Acid plus (PLA+)
• Colour: Black
• Net weight: 1 kg spool
• Compatibility: FDM/FFF 3D printers, any brand
• Mechanical properties: improved toughness and reduced brittleness compared with standard PLA
• Dimensional behaviour: good stability suitable for accurate prints

How to use

Load the filament into any FDM/FFF printer according to the printer manufacturer's instructions. Use typical PLA print temperatures and settings as a starting point; calibrate nozzle temperature, bed temperature and print speed to match your specific printer and model geometry. Store the spool in a dry environment or sealed container with desiccant when not in use to maintain filament dryness and print consistency. Clean the nozzle and extruder path if switching from other materials to avoid contamination.

Usage recommendations

For best results, start with standard PLA temperature ranges and adjust incrementally: increase temperature slightly if layer adhesion is poor or reduce speed for finer details. Use a heated bed if available to improve first-layer adhesion and consider a brim or raft for small bases. Avoid prolonged exposure to humid conditions to prevent print quality degradation.
