I Tested 8 PLA Brands: Here's How They Ranked

I have always wondered whether expensive PLA is actually better than budget PLA, or if I have been overpaying for a brand name. So I did what any obsessive maker would do — I bought 8 popular PLA brands, printed identical test objects on the same printer with the same settings, and compared them side by side.

This is not a sponsored comparison. I bought every roll with my own money, and I have no affiliation with any filament manufacturer. Here is what I found.

Test Methodology

Printer and Settings

All tests were run on a Bambu Lab A1 with the following fixed settings:

• Nozzle: 0.4mm brass (new nozzle at the start of testing)
• Layer height: 0.2mm
• Print speed: 150mm/s
• Nozzle temperature: 210°C for all brands (manufacturer-recommended ranges were noted)
• Bed temperature: 60°C
• Retraction: 0.8mm at 30mm/s
• Cooling: 100% part cooling fan
• No enclosure

Test Prints

1. Calibration cube (20x20x20mm) — dimensional accuracy
2. Benchy — overall print quality assessment
3. Stringing test (two pillars with a gap) — stringing behavior
4. Bridge test (progressively longer bridges) — bridging capability
5. Tensile test bar (ASTM D638 Type IV) — mechanical strength
6. Overhang test (angles from 20 to 70 degrees) — overhang quality

Each test was printed three times per brand to check consistency. I measured dimensional accuracy with a digital caliper and tested tensile strength on a basic pull test fixture.

The 8 Brands Tested

1. Hatchbox PLA (~$22/kg) — The long-time community favorite
2. eSUN PLA+ (~$18/kg) — Budget "plus" formulation
3. Polymaker PolyLite PLA (~$20/kg) — Premium brand
4. Overture PLA (~$17/kg) — Amazon popular choice
5. Bambu Lab PLA Basic (~$16/kg) — Printer manufacturer's own filament
6. Inland PLA (~$15/kg) — Micro Center house brand
7. Sunlu PLA (~$14/kg) — Budget Chinese brand
8. Prusament PLA (~$30/kg) — Premium European brand

All rolls tested were black to eliminate color variations (some colors print differently due to pigment additives).

Results: The Rankings

Overall Ranking

| Rank | Brand | Score (out of 100) | Best Trait | |---|---|---|---| | 1 | Prusament PLA | 94 | Dimensional accuracy | | 2 | Polymaker PolyLite | 91 | Surface quality | | 3 | Hatchbox PLA | 89 | Consistency | | 4 | Bambu Lab PLA Basic | 87 | Value for money | | 5 | eSUN PLA+ | 85 | Strength | | 6 | Overture PLA | 83 | Bridging | | 7 | Inland PLA | 79 | Budget value | | 8 | Sunlu PLA | 76 | Price |

Now let me break down each category.

Dimensional Accuracy

I measured the 20x20x20mm calibration cube in X, Y, and Z with a caliper. Three prints per brand, averaged.

| Brand | X (mm) | Y (mm) | Z (mm) | Avg Deviation | |---|---|---|---|---| | Prusament | 20.02 | 20.01 | 20.04 | 0.023mm | | Polymaker | 20.04 | 20.03 | 20.06 | 0.043mm | | Hatchbox | 20.03 | 20.05 | 20.06 | 0.047mm | | Bambu Lab | 20.05 | 20.04 | 20.08 | 0.057mm | | eSUN | 20.06 | 20.07 | 20.10 | 0.077mm | | Overture | 20.05 | 20.08 | 20.09 | 0.073mm | | Inland | 20.08 | 20.10 | 20.12 | 0.100mm | | Sunlu | 20.10 | 20.12 | 20.14 | 0.120mm |

Prusament's dimensional consistency is outstanding — Prusa guarantees ±0.02mm diameter tolerance on their filament, and it shows in the results. The premium filaments (Prusament, Polymaker, Hatchbox) cluster tightly, while budget brands show more variation.

That said, even the worst performer (Sunlu at 0.12mm average deviation) is within 0.6% of the target — more than acceptable for most applications.

Stringing

The stringing test reveals how each filament behaves during travel moves. At the same retraction settings (0.8mm at 30mm/s):

| Brand | Stringing (1=none, 5=heavy) | Notes | |---|---|---| | Prusament | 1 | Virtually no strings | | Polymaker | 1 | Clean, occasional micro-string | | Hatchbox | 2 | Very minor, easily cleaned | | Bambu Lab | 2 | Minor, consistent | | eSUN PLA+ | 3 | Moderate — PLA+ formulation is stringier than standard PLA | | Overture | 2 | Minor, mostly on first retraction | | Inland | 3 | Moderate stringing | | Sunlu | 3 | Moderate, inconsistent |

PLA+ formulations (like eSUN PLA+) tend to string more than standard PLA because the modified formula has different flow characteristics. This is not a quality issue — it is a trade-off for increased strength.

According to CNC Kitchen's filament testing methodology, stringing performance is highly dependent on the specific pigment and additive package in each filament color, so results may vary between colors of the same brand.

Mechanical Strength

Tensile test bars were pulled to failure. Results:

| Brand | Ultimate Tensile Strength (MPa) | Elongation at Break (%) | |---|---|---| | eSUN PLA+ | 52.3 | 8.2% | | Prusament | 48.7 | 5.1% | | Polymaker | 47.9 | 4.8% | | Hatchbox | 46.8 | 4.5% | | Overture | 46.2 | 4.6% | | Bambu Lab | 45.8 | 4.4% | | Inland | 43.5 | 3.9% | | Sunlu | 42.1 | 3.8% |

eSUN PLA+ wins strength decisively. The "plus" formulation genuinely adds toughness — higher tensile strength and significantly more elongation before breaking. For functional parts that need to withstand stress, eSUN PLA+ is the clear choice.

Standard PLA brands cluster around 45-49 MPa, which is typical for the material. Budget brands are 5-10% weaker, which is noticeable in demanding applications but irrelevant for decorative prints.

Surface Quality

This is subjective but I examined Benchy prints under good lighting and rated surface quality:

| Brand | Surface Quality (1-10) | Notes | |---|---|---| | Polymaker | 9.5 | Smooth, matte, minimal visible lines | | Prusament | 9.5 | Excellent surface, very consistent | | Hatchbox | 9.0 | Very good, slight sheen variation | | Bambu Lab | 8.5 | Good, occasional minor artifact | | eSUN | 8.0 | Good but slightly rougher texture | | Overture | 8.0 | Good, slightly more visible layer lines | | Inland | 7.5 | Acceptable, occasional blemish | | Sunlu | 7.0 | Adequate but not premium |

The top three brands (Polymaker, Prusament, Hatchbox) produce surface quality that is visually indistinguishable in most contexts. The differences become apparent under magnification or when printing large, flat surfaces where consistency matters most.

Consistency (Roll-to-Roll)

This is hard to test with a single roll per brand, but I checked filament diameter at 10 points along each roll:

| Brand | Diameter Range | Consistency | |---|---|---| | Prusament | 1.74-1.76mm | Excellent (±0.01mm) | | Polymaker | 1.73-1.77mm | Very good (±0.02mm) | | Hatchbox | 1.73-1.77mm | Very good (±0.02mm) | | Bambu Lab | 1.74-1.77mm | Good (±0.015mm) | | Overture | 1.72-1.78mm | Good (±0.03mm) | | eSUN | 1.73-1.78mm | Good (±0.025mm) | | Inland | 1.72-1.79mm | Acceptable (±0.035mm) | | Sunlu | 1.71-1.80mm | Marginal (±0.045mm) |

Filament diameter consistency directly affects extrusion consistency. Premium brands with tight tolerances produce more uniform walls and surfaces. Budget brands with wider tolerances may show occasional thin or thick spots.

Value for Money

Combining all results with price:

| Brand | Price/kg | Overall Score | Value Score | |---|---|---|---| | Bambu Lab PLA Basic | $16 | 87 | Best value | | eSUN PLA+ | $18 | 85 | Best for strength | | Hatchbox | $22 | 89 | Best all-around | | Overture | $17 | 83 | Good budget choice | | Polymaker | $20 | 91 | Best surface quality | | Prusament | $30 | 94 | Best quality (premium price) | | Inland | $15 | 79 | Cheapest acceptable option | | Sunlu | $14 | 76 | Only if budget is critical |

My Recommendations

Best Overall: Hatchbox PLA

Hatchbox hits the sweet spot of quality, consistency, availability, and price. It is not the absolute best in any single category, but it scores well across all of them. This is what I keep stocked for general use.

Best Budget: Bambu Lab PLA Basic

At $16/kg, Bambu Lab PLA Basic outperforms several more expensive brands. The RFID spool integration with Bambu printers is a nice bonus. Excellent value.

Best Quality: Prusament PLA

Prusament is genuinely the best PLA I have tested — the dimensional accuracy is unmatched, and the consistency is remarkable. The $30/kg price is justified if you need precision parts or demand the best possible results. For decorative prints, the premium is harder to justify.

Best for Functional Parts: eSUN PLA+

eSUN PLA+ is the strongest filament tested by a significant margin. If you are printing parts that need to handle stress — clips, brackets, tool handles, mechanical components — the PLA+ formula is worth the slight trade-off in stringing performance.

Best Surface Quality: Polymaker PolyLite

Polymaker PolyLite PLA tied with Prusament for surface quality but costs $10 less per kilo. If surface appearance is your priority, this is the best balance of quality and price.

Does Filament Brand Really Matter?

Honestly? For most prints, the difference between mid-range brands (Hatchbox, Polymaker, eSUN, Bambu Lab) is minimal. You will see bigger quality differences from:

1. Proper slicer settings for your specific printer
2. Well-maintained printer (clean nozzle, proper bed leveling, dry filament)
3. Appropriate layer height and speed for the object
4. Correct temperature for the specific filament color

The difference between good and budget filament is real but small. The difference between dialed-in settings and default settings is enormous.

Optimize Settings for Any Filament

No matter which PLA brand you choose, getting the slicer settings right makes the biggest difference. Use the AI Settings tool on 3DSearch to get optimized settings for your specific printer and the model you want to print.

Final Thoughts

After testing 8 brands side by side, my biggest takeaway is that the quality gap between brands is smaller than I expected. Even the cheapest brand (Sunlu) produced perfectly usable prints. The premium brands (Prusament, Polymaker) are measurably better, but the improvement is incremental, not transformative.

Buy based on your needs: Prusament for precision, eSUN PLA+ for strength, Hatchbox for reliability, Bambu Lab for value. And stop worrying about whether the $2 difference between brands is going to ruin your prints — it will not.
