3D Printer Filament eSun PLA 1.75 mm Light Grey 1 kg

eSun PLA 1.75 mm Light Grey 1 kg is a general-purpose biodegradable thermoplastic filament designed for FDM 3D printing. The 1.75 mm diameter spool provides consistent feeding through most common hotend setups and is formulated to offer easy extrusion, low warp and reliable dimensional stability. The light grey color produces neutral-toned prints suitable for prototypes, functional prototypes, household items and decorative parts where a muted finish is preferred.

Advantages

This PLA filament is engineered for user-friendly printing with predictable flow characteristics and reduced stringing. It has good layer adhesion and cooling response, which supports fine detail and consistent surface quality without requiring specialized heated chambers. The biodegradable base polymer simplifies disposal compared with many petroleum-based plastics, while the light grey pigment helps mask small surface imperfections and is well suited for post-processing such as sanding and painting.

Suitable for

• Rapid prototyping and concept models
• Household items and organizers
• Decorative parts, figurines and display models
• Functional prototypes that do not require high heat resistance
• Educational projects and beginner 3D printing

Key specifications

• Material type: Polylactic Acid (PLA), biodegradable thermoplastic
• Diameter: 1.75 mm nominal filament thickness for FDM printers
• Spool weight: 1 kg usable filament per spool
• Color: Light grey, neutral tone suitable for finishing
• Compatibility: Designed for standard 1.75 mm hotend setups and common FDM extruders
• Print characteristics: Low warping, good dimensional stability, suitable for layer detail

How to use

Load the filament into a compatible 1.75 mm extruder according to your printer manufacturer instructions. Typical printing temperatures for this PLA are in the range recommended by the printer or filament manufacturer; start with a moderate nozzle temperature and adjust based on extrusion consistency and layer bonding. Use a heated bed if available to improve first-layer adhesion, or employ adhesives such as glue stick or blue painter's tape on a cold bed. Allow parts to cool gradually for best dimensional accuracy and to reduce deformation.

Usage recommendations

Store the filament in a dry environment away from direct sunlight and moisture. For long-term storage, keep the spool in a sealed bag with desiccant. When changing colors or materials, purge the hotend to prevent contamination. For improved surface finish, adjust print speed and cooling settings and consider post-processing such as sanding, priming and painting.
