eSUN PLA+ 1,75mm giallo 1kg Refill filamento 3D (PLA+175Y1R1)

Makers prototyping functional parts or printing vibrant display models on open-frame FDM printers will appreciate this eSUN PLA+ refill. The 1 kg yellow filament comes on a master-spool-compatible refill, so you can reuse your existing spool and reduce plastic waste. With a diameter of 1.75 mm and a tight tolerance of ±0.03 mm, it feeds smoothly through Bowden and direct-drive extruders alike.

Why choose it

PLA+ offers higher toughness and less brittleness than standard PLA, making it ideal for parts that need to withstand occasional drops or flexing. The yellow colour is vivid and consistent, and the low-odour formulation keeps your workspace comfortable during long prints. Because it is a refill, you cut down on single-use spools and save storage space.

Ideal use cases

• Functional prototypes that require better impact resistance
• Decorative models, toys, and visual aids in bright yellow
• Educational projects and STEM workshops
• Printing with reusable master spools to minimise waste

Good to know

Store the filament in a dry box or resealable bag with desiccant when not in use. The refill fits standard master spools; simply slide it onto your spool and secure the sides. No heated bed is strictly required, but a bed temperature up to 60 °C improves adhesion on glass or PEI surfaces.
