PLA Filament Sunlu PLA Classic 1.75 mm 1 kg — White

Sunlu PLA Classic White filament is a 1.75 mm, 1 kg spool of PLA bioplastic designed for FDM/FFF 3D printers. It provides low-warp printing and reliable layer adhesion, making it suitable for prototypes, visual models and everyday household parts. The material prints at standard PLA temperatures and works with common slicer profiles and consumer printers.

Advantages

Sunlu PLA Classic offers an improved PLA formulation with higher mechanical strength and a matte surface finish. The filament is manufactured with a consistent diameter and careful winding to reduce clogs and feeding issues. It is easy to extrude and produces parts with good dimensional stability and straightforward support removal, which speeds up post-processing.

Suitable for

• Concept models and prototypes
• Visual and presentation prints with a matte white finish
• Household parts and fixtures with moderate mechanical demands
• Hobbyist and educational projects

When it may not be suitable

PLA is a brittle thermoplastic compared with engineering materials and may not be appropriate for parts that require high impact resistance, long-term outdoor exposure, or high-temperature performance. For functional components exposed to heat, chemicals or heavy mechanical stress, consider alternative materials.

Key specifications

• Material: PLA (polylactic acid)
• Diameter: 1.75 mm (tolerance ±0.02 mm)
• Spool weight: 1 kg
• Recommended nozzle temperature range: 190–230 °C
• Optimal print speed range: 60–150 mm/s (supports up to 600 mm/s)
• Density: 1.24 g/cm³
• Colour: White

How to use

Load the 1.75 mm filament into your FDM/FFF printer following the manufacturer’s filament-loading procedure. Set the nozzle temperature within the recommended 190–230 °C range and use standard PLA print settings in your slicer (moderate print speed, cooling enabled). Start with the optimal speed range of 60–150 mm/s for a balance of detail and productivity, and adjust retraction and cooling settings to minimise stringing and improve surface quality. Remove supports carefully after cooling to simplify post-processing.

What to consider before purchase

• Ensure your printer supports 1.75 mm filament and the stated nozzle temperature range
• Consider whether PLA’s mechanical properties meet the requirements of your application
• Check spool weight and storage conditions to prevent moisture absorption

Usage recommendations

Use cooling fans for best surface quality, store the spool sealed with desiccant to preserve filament properties, and print test samples when changing slicer profiles or temperature to dial in optimal settings for your printer.
