eSUN PLA+ 1.75mm Fire Engine Red 1kg Refill 3D Filament PLA+175O-FR1R1

3D printing enthusiasts often struggle with brittle filaments that snap mid-print or produce weak, fragile parts. The eSUN PLA+ Fire Engine Red solves this by offering enhanced toughness and reliability, making it ideal for functional prototypes and everyday prints that need to withstand real-world use. This 1kg refill spool is designed for users who already have a reusable spool, reducing plastic waste and cost.

Who is it for

This filament is perfect for hobbyists, educators, and professionals who demand more from their PLA. If you need parts with higher impact resistance, better layer adhesion, and a vibrant, eye-catching red finish, PLA+ is the upgrade you've been looking for. It's compatible with most FDM 3D printers that accept 1.75mm filament.

Main features

• Enhanced PLA+ formula: up to 10x more impact strength than standard PLA
• Vibrant fire engine red color with excellent opacity and consistent finish
• Precision diameter: 1.75mm ±0.03mm for reliable extrusion and minimal clogs
• Tangle-free winding and vacuum-sealed with desiccant for moisture-free printing
• Eco-friendly refill format: use with eSUN reusable spools or your own
• Low odor and low warping, prints easily on open-frame printers

Tips

For best results, print a temperature tower to fine-tune your settings. Store unused filament in a sealed container with desiccant to prevent moisture absorption, which can cause brittleness and poor print quality. If you're new to refill spools, carefully transfer the filament onto a compatible spool, ensuring the winding remains tight and tangle-free.
