Best PLA Filament Brands for 3D Printing: Six Options Tested

Introduction

Choosing the right PLA filament brand can feel overwhelming when dozens of manufacturers offer similar-looking products. This review compares six popular PLA filament brands across print quality, color selection, pricing, and availability to help you make an informed choice for your 3D printer.

The six brands tested are Bambu Lab, Polymaker, Sunlu, Elegoo, Deeplee, and eSun. Each brand offers variations including Basic PLA, PLA Plus (a stronger modified version), and High-speed PLA (suitable for printers reaching 600 mm per minute velocity). All prints were made on a Bambu Lab X1C using a calibration test design, with each print taking between 1 hour 45 minutes and 2 hours to complete.

Print Quality and Calibration Results

All six filaments produced excellent overhang results, successfully printing all the way to 80 degrees. Dimensional accuracy across cylinder diameters and rectangle lengths showed minimal variation between brands, with all measurements falling within a small range of the design specifications.

Bambu Lab pink Basic PLA delivered excellent overhang performance and clean bridging with only a few stringers. Sunlu orange High-speed PLA matched the overhang results but showed slightly more stringing and one sagging strand during bridging. eSun yellow PLA Plus achieved the same 80-degree overhang success with bridging quality similar to Sunlu, including one sagging strand and comparable stringing.

Polymaker blue Polylite PLA excelled in bridging quality, matching Bambu Lab’s clean results with minimal stringing, though it did show one loose strand at 60 degrees. Elegoo black PLA Plus reached 80 degrees on overhangs with excellent bridging similar to Polymaker and Bambu Lab, but produced more stringers than other filaments tested. Deeplee sky blue PLA achieved the same overhang success with bridging quality comparable to Polymaker, Bambu Lab, and Elegoo, with stringing levels similar to the Elegoo filament.

Bridging and Stringing Performance

Bridging performance revealed subtle differences between brands. Bambu Lab and Polymaker produced the cleanest bridging with minimal sagging and few stringers. Sunlu and eSun both showed one sagging strand but otherwise acceptable results. Elegoo and Deeplee produced more stringers overall, though bridging quality remained acceptable for both.

These differences are minor enough that they would not significantly impact most printing projects. The variation likely reflects normal batch-to-batch tolerances rather than fundamental quality differences between brands.

Color Options and Availability

Color selection varies considerably across brands. For Basic PLA, most brands offer 28 to 30 colors, with Deeplee offering 19 and eSun offering 11. Polymaker leads in PLA Plus options with 33 colors, followed by Sunlu at 26. For High-speed PLA, eSun offers the most at 14 colors. Bambu Lab does not currently offer PLA Plus or High-speed PLA variants.

When combining all single-color options across Basic PLA, PLA Plus, and High-speed PLA, Polymaker leads with 72 total options, followed by Sunlu at 65, Elegoo at 59, Deeplee at 45, eSun at 43, and Bambu Lab at 30. These numbers reflect the market as of March 2025 and change regularly as brands update their offerings.

Availability differs by region and retailer. Amazon carries all brands except Bambu Lab, with Prime shipping typically arriving within one to two days. Bambu Lab filaments are available directly from their website with free shipping on orders over $49, typically arriving within a week in the US.

Pricing and Spool Material

Polymaker commands the highest price across all variants at $23 to $25 per spool. Bambu Lab Basic PLA costs $20 per spool. Sunlu, eSun, and Elegoo fall in the middle range at $16 to $20 depending on the variant. Deeplee offers the lowest pricing at $11 to $13 per spool, though certain colors may cost $18 to $19.

All brands offer volume discounts for multiple spools, which can reduce per-spool costs significantly.

Spool Material and Reusability

Spool material differs between brands. Polymaker, eSun, and Deeplee use cardboard spools, while Sunlu, Elegoo, and Bambu Lab provide plastic spools. Bambu Lab spools are reusable by twisting the two halves apart and inserting a new refill. Bambu Lab spools also include RFID tags for use with the Bambu Lab AMS (Automated Material System), adding convenience for users of that ecosystem.

Conclusion

All six brands tested produced high-quality prints with no significant differences in dimensional accuracy or overhang performance. The choice between them depends more on your specific needs: color selection preferences, budget constraints, printer compatibility, and spool reusability features.

For maximum color options and willingness to pay premium prices, Polymaker and Sunlu offer the broadest selections. For budget-conscious printing, Deeplee provides the lowest entry cost. For Bambu Lab printer owners seeking ecosystem integration and reusable spools, Bambu Lab filaments offer practical advantages. Elegoo and eSun occupy the middle ground with solid quality, reasonable pricing, and good availability through Amazon.
