Filament spool eSun PLA-BASIC 1.75 mm — PLA 1 kg refill, blue

eSun PLA-BASIC 1.75 mm is a 1 kg refill spool of blue PLA filament designed for FDM/FFF 3D printers that accept 1.75 mm filament. This standard PLA material offers straightforward printability and is intended for general-purpose prototyping, model making and household parts where a biodegradable thermoplastic is suitable. The spool provides a consistent diameter and a smooth surface finish that helps maintain reliable extrusion during routine printing tasks.

Advantages

The filament combines ease of use with dimensional stability, making it suitable for users who need predictable layer adhesion and low warping in everyday prints. Its 1.75 mm diameter is widely supported by consumer and prosumer 3D printers, while the 1 kg spool size balances usage length and storage convenience. The blue color delivers uniform pigmentation for visible prototypes and functional parts.

Suitable for

• Prototyping and concept models
• Hobbyist and educational projects
• Household items and functional parts
• Visual models and display pieces

Key specifications

• Material: polylactic acid (PLA)
• Filament diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Colour: blue
• Recommended printing technology: FDM/FFF

How to use

Load the spool onto the printer’s filament holder and thread the filament into the extruder according to your printer manufacturer’s instructions. Set the nozzle temperature and print bed conditions to values suitable for PLA on your specific printer — typical nozzle temperatures range around 190–220 °C and a non-heated or mildly heated bed is usually sufficient. Calibrate extrusion settings, bed leveling and first-layer height before starting the print to ensure consistent results.

Usage recommendations

Store the spool in a dry environment or sealed container with desiccant to reduce moisture absorption. If filament shows signs of moisture (brittleness, poor extrusion, stringing), consider drying it according to recommended PLA drying procedures. Use standard print cooling settings and moderate print speeds for best surface quality.
