Filament eSun PLA+ 1.75 mm White 1 kg — Polylactic Acid Plus (PLA+)

eSun PLA+ 1.75 mm White is a 1 kg spool of polylactic acid plus (PLA+) filament for FDM/FFF 3D printers. Based on PLA, this modified material is formulated to print easily while offering improved toughness and better layer adhesion compared with standard PLA. It produces smooth surfaces and is suitable for conceptual models, rapid prototyping and functional parts that require higher impact resistance. PLA+ is an environment-friendly thermoplastic and the filament stated here is compatible with printers that accept 1.75 mm filament.

Advantages

PLA+ combines good strength, rigidity and enhanced toughness to reduce brittleness and increase impact resistance. The material is easy to print, yields smooth printed surfaces and supports higher printing speeds. Its balanced mechanical properties make it suitable for parts that need improved durability compared with standard PLA. The filament is intended for general compatibility with any brand accepting 1.75 mm filament.

Suitable for

• Conceptual models and visual prototypes
• Rapid prototyping and iterative design
• Functional parts with moderate impact requirements
• Hobby prints and decorative objects requiring smooth surface finish

When it may not be suitable

PLA+ improves toughness over standard PLA but is not as heat-resistant as engineering plastics such as ABS or PETG; it may deform under sustained high temperatures. For parts requiring very high chemical resistance, extreme mechanical loads, or prolonged outdoor exposure, consider alternative materials.

Key specifications

• Material: Polylactic Acid Plus (PLA+)
• Diameter: 1.75 mm
• Net weight: 1 kg
• Colour: White
• Impact strength: approximately 9 kJ/m²
• Tensile modulus: approximately 1973 MPa

How to use

Load the 1.75 mm filament spool into a compatible FDM/FFF 3D printer and set printing parameters according to your printer and nozzle. Start with typical PLA settings and adjust nozzle temperature, print speed and retraction to optimise surface quality and layer adhesion. Ensure the build surface is prepared for good first-layer adhesion and store the filament in a dry place to avoid moisture absorption.

What to consider before purchase

• Printer compatibility with 1.75 mm filament
• Required mechanical properties: toughness vs. heat resistance
• Desired surface finish and post-processing needs
• Storage conditions to prevent moisture uptake

Usage recommendations

For best results, print PLA+ with a nozzle temperature and bed settings similar to PLA, tune print speed and cooling for smoother surfaces, and keep filament dry. Use this filament for prototypes and functional parts that benefit from improved impact resistance compared with standard PLA.
