eSUN PLA Filament 1.75mm 2x1KG Spools - Upgraded Tough PLA

In this review of the eSUN PLA Filament 1.75mm, the bottom line is simple: this two-spool pack is aimed at hobbyists and makers who want a user-friendly filament with better toughness than ordinary PLA without sacrificing printability. The reviewer found it easy to feed and print, with consistent diameter and good surface finish, making it a reliable choice for everyday FDM projects where durability and smooth appearance matter. Beginners will appreciate the low warping and low odor, while more advanced users will value the dimensional accuracy for repeatable parts.

Key Features

• Improved Toughness: Upgraded PLA formulation delivers higher strength and better toughness than standard PLA, reducing brittle failures during handling or in functional parts.
• Dimensional Accuracy: Each 1 kg spool maintains an accuracy of +/- 0.03 mm, which helps ensure consistent feeding and predictable layer lines across prints.
• Tangle Free Winding: The filament is wound with good roundness and tight diameter tolerance so it feeds smoothly without overlaps or tangles.
• Low Clogging Risk: Melt behavior and consistent diameter reduce nozzle clogs and help achieve a higher successful print rate with fewer interruptions.
• Eco-conscious Packaging: Filaments come vacuum sealed with a desiccant and use recyclable spool and box materials to keep filament dry and reduce waste.
• Wide Applications: Good layer adhesion and toughness makes it suitable for functional parts, decor, cosplay, and light mechanical components.

Who It's For

This eSUN upgrade is best for hobbyists, educators, and makers who want a dependable, easy-to-print PLA that tolerates faster printing and occasional functional use. Because it keeps PLA's low-warp characteristics, it works well on most 1.75 mm FDM printers and is friendly for users who are still dialing in print settings.

Those who need high-temperature performance, specialty engineering plastics, or absolute industrial-grade mechanical properties should look elsewhere. Also, if absolute bed adhesion is critical for very large flat parts, users may need an optimized bed surface or adhesive, since customer feedback on bed adhesion is mixed.

Pros & Cons

Pros

• Consistent diameter and +/- 0.03 mm accuracy reduce print variation and feeding issues.
• Improved toughness over ordinary PLA makes printed parts less brittle and more usable.
• Good winding and roundness prevent tangles and lower the chance of failed prints from snags.
• Eco-friendly packaging with vacuum seal and desiccant helps filament storage and longevity.

Cons

• Bed adhesion reports are mixed, so some surfaces may require glue, tape, or a textured build plate for best first-layer results.
• While tougher than standard PLA, it is not a substitute for ABS, PETG, or nylon when heat or extreme mechanical strength is required.

Our Verdict

The eSUN Upgraded PLA 1.75 mm two-spool pack is a practical, cost-effective filament for general-purpose 3D printing where ease of use and improved toughness are priorities. It offers consistent diameter, reliable winding, and recyclable packaging, making it good value for hobbyists and small workshops that need repeatable results without specialty materials.

Frequently Asked Questions

Will this filament work on my 1.75 mm FDM printer?
Yes, it is designed for standard 1.75 mm FDM printers and is produced with tight diameter tolerance for consistent feeding.

How should I store the spools?
Keep them in the sealed vacuum bag with the desiccant when not in use, or store in a dry box to maintain optimal filament condition.

Does it require a special bed surface?
Not usually; it has low warping, but some users report mixed bed adhesion so a heated bed or adhesive aid may be helpful for certain surfaces.
