Sunlu PLA+ Filament (Green) — Sunlu PLA+ G 1.75 mm compatible 3D printing filament

Sunlu PLA+ Filament (Green) is a 1.75 mm PLA+ material formulated to deliver improved toughness and a good surface finish for FDM/FFF 3D printing. It is intended for users who need prints with higher impact resistance and consistent color while maintaining ease of printing and dimensional accuracy.

Advantages

The filament offers enhanced mechanical properties with significantly higher impact resistance than many standard PLA grades, together with low shrinkage and good interlayer adhesion. Its tight diameter tolerance and even winding reduce feeding issues and support reliable, repeatable results across a range of printers and print settings.

Suitable for

• Functional prototypes and end-use parts requiring higher toughness
• Detailed models and decorative prints where surface finish matters
• Hobbyist and professional FDM/FFF printers using 1.75 mm filament

When it may not be suitable

This PLA+ has a moderate heat resistance (Vicat ~54 °C, HDT ~53 °C) and therefore is not recommended for applications exposed to continuous high temperatures or for parts that must withstand hot environments. It is also not intended for applications requiring very high elongation or extreme flexibility.

Key specifications

• Diameter: 1.75 mm (±0.02 mm)
• Density: 1.23 g/cm³

• Heat deflection temperature (HDT): 53 °C
• Melting temperature: 164 °C
• Melt flow rate: 6.3 g/10 min
• Tensile strength: 64 MPa
• Elongation at break: 17 %
• Flexural strength: 86 MPa
• Flexural modulus: 2907 MPa
• IZOD impact strength (X–Y): 3.5 kJ/m²; typical overall impact resistance up to 8 kJ/m²
• Colour: Green

How to use

Load the 1.75 mm filament onto any compatible FDM/FFF printer and use recommended print temperatures and speeds to achieve optimal results. Typical printing parameters are 195–205 °C at 50–100 mm/s or 205–220 °C at 100–300 mm/s; adjust cooling and retraction settings to minimise stringing and to suit your model and printer. Ensure the spool is mounted so the evenly wound filament unwinds smoothly to avoid tangles.

What to consider before purchase

• Confirm your printer supports 1.75 mm filament
• Check the required heat resistance for your application (Vicat ~54 °C)
• Plan printing temperatures and speeds according to your printer and nozzle size

Usage recommendations

For consistent prints, use moderate cooling and calibrate extrusion multiplier. Store the filament dry and spool-mounted to preserve dimensional stability and avoid moisture-related defects.
