Best PETG Filament in 2026: 8 Brands Tested and Ranked

PETG is the filament I reach for when a part needs to survive the real world. It is stronger than PLA, more heat-resistant, has some flexibility so it does not shatter on impact, and it is food-safe when printed correctly. But PETG is also pickier than PLA — it strings more, sticks harder to build plates, and requires tighter temperature control. Choosing the right brand makes a significant difference in your results.

After printing with dozens of different PETG brands over the past year, I noticed meaningful differences in stringing behavior, layer adhesion, and overall print quality that prompted me to run a proper side-by-side test. I tested eight popular PETG filaments to find the best options for 2026.

Why Choose PETG Over PLA

Before diving into specific brands, let me quickly explain when PETG is the right choice. PLA starts softening around 55-60°C, which means anything left in a car, near a window in summer, or used in an outdoor application will deform. PETG handles temperatures up to about 80°C before softening. It also has better impact resistance — where PLA will crack and shatter, PETG will flex and absorb energy.

The trade-off is printability. PETG strings more than PLA, adheres to build plates almost too well (it can damage glass beds), and requires higher temperatures. But with the right settings and a good filament brand, these challenges are manageable. The Prusa material guide is an excellent technical reference for PETG printing.

Test Setup

Printer and Settings

All tests on a Bambu Lab A1 with a textured PEI plate:

• Nozzle: 0.4mm brass (new nozzle at start of testing)
• Layer height: 0.2mm
• Print speed: 100mm/s (slower than PLA to account for PETG's characteristics)
• Nozzle temperature: 240°C for all brands (fine-tuned per brand via temperature tower)
• Bed temperature: 80°C
• Retraction: 0.8mm at 25mm/s
• Part cooling fan: 50%
• No enclosure

Test Prints

1. Calibration cube — dimensional accuracy
2. Stringing torture test — multiple towers with varying gaps
3. Tensile test bar (ASTM D638) — mechanical properties
4. Overhang test — quality without supports at various angles
5. Bridging test — progressively longer unsupported spans
6. Water container test — waterproofness of printed vessel after 24 hours
7. Functional parts — a wrench and a carabiner clip

Each test was printed twice per brand. All filament was dried for 4 hours at 65°C in a Sunlu S2 filament dryer before testing to eliminate moisture as a variable. All rolls tested in black to minimize color-dependent variation.

Results

Overall Rankings

| Rank | Brand | Score (out of 100) | Price/kg | Standout Quality | |---|---|---|---|---| | 1 | Overture PETG | 91 | $19 | Best all-rounder value | | 2 | Polymaker PolyLite | 90 | $24 | Surface quality | | 3 | Prusament PETG | 93 | $32 | Layer adhesion and consistency | | 4 | eSUN PETG | 84 | $20 | Strength and beginner-friendly | | 5 | Hatchbox PETG | 87 | $24 | Reliability | | 6 | Sunlu PETG | 78 | $18 | Transparent options | | 7 | Inland PETG | 76 | $17 | Budget functional printing | | 8 | Amazon Basics PETG | 72 | $16 | Cheapest option |

Stringing: The PETG Challenge

PETG strings. That is the nature of the material. But some brands handle it better than others.

| Brand | Stringing Level (1=minimal, 5=extreme) | Notes | |---|---|---| | Prusament | 2 | Best in class — surprisingly clean | | Polymaker | 2 | Very good, thin easily-removable whiskers | | Hatchbox | 3 | Moderate, typical for PETG | | eSUN | 3 | Moderate, slightly thick strings | | Overture | 3 | Moderate, consistent | | Sunlu | 4 | Heavy stringing, required significant post-cleanup | | Inland | 3-4 | Above average stringing | | Amazon Basics | 4 | Above average, inconsistent |

Prusament and Polymaker both string noticeably less than the other brands at the same settings. This likely comes down to the specific polymer blend and additives that control melt viscosity.

For context, even the "level 2" PETG brands string more than most PLA. If you are coming from PLA and expecting clean travel moves, PETG will always require some adjustment — lower temperatures, Z-hop, and combing mode all help. See my stringing troubleshooting guide for specific PETG fixes.

Mechanical Strength

PETG is chosen for functional parts, so strength matters. Tensile test results:

| Brand | Tensile Strength (MPa) | Elongation at Break (%) | Layer Adhesion (qualitative) | |---|---|---|---| | eSUN | 47.8 | 12.4% | Good | | Prusament | 46.5 | 11.8% | Excellent | | Polymaker | 45.9 | 11.2% | Very good | | Hatchbox | 44.7 | 10.5% | Good | | Overture | 43.8 | 9.8% | Good | | Sunlu | 41.2 | 8.5% | Adequate |

eSUN edges out Prusament on raw tensile strength, but Prusament has noticeably better layer adhesion — parts are harder to split along layer lines. For parts where inter-layer strength matters (which is most functional applications), Prusament's superior layer adhesion makes it the stronger choice in practice.

According to CNC Kitchen's PETG testing, layer adhesion is often more important than raw tensile strength for 3D printed parts because the weakest point is almost always the layer interface, not the bulk material.

Surface Quality

Examining Benchy and calibration cube surfaces under good lighting:

| Brand | Surface Quality (1-10) | Notes | |---|---|---| | Polymaker | 9.0 | Smooth, consistent, attractive matte sheen | | Prusament | 9.0 | Excellent, very uniform | | Hatchbox | 8.5 | Very good, slight variation on large surfaces | | eSUN | 8.0 | Good, slightly more textured | | Overture | 7.5 | Decent, visible layer lines slightly more prominent | | Sunlu | 7.0 | Adequate, occasional surface blemish |

Polymaker and Prusament tie for best surface finish. Both produce a smooth, slightly glossy surface that looks professional. Budget brands show more visible layer lines and occasional inconsistencies.

Moisture Sensitivity

PETG is hygroscopic — it absorbs moisture from the air. But some formulations are more sensitive than others. I exposed each brand to ambient conditions (no sealed storage) for 7 days, then reprinted the stringing test:

| Brand | Stringing After 7 Days (1-5) | Quality Degradation | |---|---|---| | Prusament | 3 (from 2) | Minimal | | Polymaker | 3 (from 2) | Minor | | Hatchbox | 4 (from 3) | Moderate | | eSUN | 4 (from 3) | Moderate | | Overture | 4 (from 3) | Moderate | | Sunlu | 5 (from 4) | Significant |

All brands degraded after moisture exposure, but the premium brands (Prusament, Polymaker) were less affected. This suggests either a more moisture-resistant formulation or better initial drying.

The takeaway: always dry PETG before printing, regardless of brand. A filament dryer is not optional for PETG — it is essential.

Bridging Performance

PETG bridges well because of its viscosity and slow cooling. Test results for maximum clean bridge length:

| Brand | Max Clean Bridge (mm) | Notes | |---|---|---| | Overture | 45mm | Surprisingly good — best bridging | | Hatchbox | 42mm | Very good | | eSUN | 40mm | Good | | Polymaker | 38mm | Good, slight droop at longer spans | | Prusament | 38mm | Good | | Sunlu | 32mm | Moderate, sags earlier |

Overture wins bridging despite not topping other categories. This suggests good viscosity characteristics at the tested temperature.

Waterproofness

I printed thin-walled containers (1mm wall, 3 perimeters) and filled them with water for 24 hours:

| Brand | Water Retention After 24hrs | |---|---| | Prusament | No leakage | | Polymaker | No leakage | | Hatchbox | Minimal seepage | | eSUN | Minimal seepage | | Overture | Minor seepage | | Sunlu | Noticeable seepage |

The premium brands produced effectively waterproof vessels without any post-processing. Budget brands showed some water permeation through layer interfaces. For waterproof applications, use premium PETG with 5+ walls and consider sealing with epoxy for absolute certainty.

Brand-by-Brand Breakdown

1. Overture PETG — Best Overall Value

Overture PETG has been my go-to PETG for over a year, and this round of testing reinforced why. It prints cleanly at 235°C with moderate stringing that is easily controlled with proper retraction settings. Layer adhesion is strong — my tensile bars required significant force to break, and they failed in the wall, not between layers. It also won the bridging test outright.

Dimensional accuracy was plus or minus 0.08mm, which is good for PETG. The color range is solid with true blacks, clean whites, and transparent options. The spool comes vacuum sealed with desiccant, which matters more for PETG than PLA.

Optimal settings: 235°C nozzle, 80°C bed, 40mm/s, 50% fan, 4mm retraction. Price: ~$19 per kg.

For the money, Overture PETG is hard to beat. It is not the absolute best in any single metric, but it is good in everything and the price is right.

2. Polymaker PolyLite PETG — Best Print Quality

Polymaker PolyLite PETG produces the cleanest surface finish of any PETG I have tested. Walls are smooth, layer lines are minimal, and the overall appearance is a step above typical PETG. The formulation seems optimized for printability, with less stringing than most competitors.

Diameter consistency was plus or minus 0.02mm — the tightest tolerance in this group. Color accuracy is excellent, with their transparent blue being particularly beautiful when printed in vase mode.

Optimal settings: 240°C nozzle, 80°C bed, 45mm/s, 60% fan, 3.5mm retraction. Price: ~$24 per kg.

The premium price is justified if surface quality matters for your application. For functional parts where appearance is secondary, the extra cost over Overture is harder to justify.

3. eSUN PETG — Best for Beginners and Strength

eSUN PETG is the most forgiving PETG I tested. It has a wider printable temperature range (225-245°C) and tolerates imperfect settings better than more finicky brands. It also posted the highest raw tensile strength (47.8 MPa) in testing.

The formulation produces less stringing than average, which is PETG's biggest headache for beginners. Dimensional accuracy was plus or minus 0.1mm, which is acceptable for functional parts. eSUN also provides good documentation for their filaments, and the community knowledge base around eSUN materials is extensive.

Optimal settings: 235°C nozzle, 80°C bed, 40mm/s, 50% fan, 4mm retraction. Price: ~$20 per kg.

If you are new to PETG or need the strongest possible parts, this is where I would start.

4. Prusament PETG — Best Consistency and Quality

Prusament PETG lives up to Prusa's manufacturing reputation. The plus or minus 0.02mm diameter guarantee with published inspection data means you know exactly what you are getting. Every roll prints identically.

Quality is excellent across the board. Smooth surfaces, minimal stringing with proper settings, the best layer adhesion in testing, the best moisture resistance, and waterproof parts without post-processing. The material has a slight gloss that looks professional. Prusa's spool tracking system lets you verify quality control data for your specific spool, which is a unique feature no other brand offers.

Optimal settings: 240°C nozzle, 85°C bed, 40mm/s, 50% fan, 3.5mm retraction. Price: ~$32 per kg.

The price is the highest in this roundup, and availability can be limited for popular colors. But if consistency is critical for your workflow, Prusament PETG is worth the premium.

5. Hatchbox PETG — Most Reliable

Hatchbox PETG delivers the same reliability that makes their PLA popular. You know what you are getting with every roll, and it just works. Print quality is good without being exceptional, and the material handles well across a range of printers and settings.

I have been buying Hatchbox PETG for years and have never received a bad roll. That consistency is valuable when you are printing functional parts that need to be repeatable. Diameter tolerance is plus or minus 0.03mm.

Optimal settings: 235°C nozzle, 80°C bed, 40mm/s, 50% fan, 4mm retraction. Price: ~$24 per kg.

The price is mid-range and the color selection is more limited than some competitors. But for a worry-free PETG experience, Hatchbox delivers.

6. Sunlu PETG — Best Transparent

Sunlu PETG offers something interesting — their transparent and translucent PETG colors are genuinely impressive. PETG's natural clarity means you can print light covers, lampshades, and decorative pieces that diffuse light beautifully.

Standard opaque colors print well too, with decent surface quality and adequate stringing control. However, Sunlu showed the most stringing, weakest strength, worst moisture sensitivity, and lowest surface quality among the established brands in my detailed testing.

Optimal settings: 235°C nozzle, 80°C bed, 35mm/s, 50% fan, 4mm retraction. Price: ~$18 per kg.

Printing transparent PETG at lower speeds (35mm/s) and higher temps (240°C) maximizes the optical clarity. The results are surprisingly close to actual clear plastic when printed in single-wall vase mode. For transparent or translucent parts, Sunlu is the pick. For functional opaque parts, spend a few dollars more on a higher-ranked brand.

7. Inland PETG — Budget Option

Inland PETG provides serviceable PETG at a budget price. Print quality is acceptable, with slightly more stringing than the top-tier options and marginally less consistent diameter (plus or minus 0.04mm). For functional parts where appearance is not critical, it gets the job done.

Optimal settings: 235°C nozzle, 80°C bed, 40mm/s, 50% fan, 5mm retraction. Price: ~$17 per kg.

The lower price makes it a good choice for prototyping or parts that will be painted or enclosed. I would not recommend it for visible or aesthetic applications.

8. Amazon Basics PETG — Budget with Caveats

Amazon Basics PETG is the cheapest PETG I tested, and the results reflect the price. It prints but requires more effort to get good results. Stringing is above average, diameter consistency is plus or minus 0.05mm (the widest in this group), and surface quality is rougher than dedicated filament brands.

Optimal settings: 235°C nozzle, 80°C bed, 35mm/s, 50% fan, 5mm retraction. Price: ~$16 per kg.

For non-critical prototyping, it is adequate. I would not use it for parts that need to look good or perform reliably.

PETG Printing Tips (Any Brand)

These apply regardless of brand:

1. Dry your filament. Every time. No exceptions. Four hours at 65°C minimum. PETG absorbs moisture faster than PLA. Popping sounds during printing and rough surface texture are signs of wet filament. A filament dryer is practically essential for PETG.

2. Use a textured PEI bed. PETG bonds too aggressively to smooth PEI and can damage the surface. A textured PEI spring steel sheet releases cleanly. Apply a thin layer of glue stick as a release agent if needed.

3. Reduce fan speed. PETG needs less cooling than PLA — typically 40-60% fan speed. Too much cooling causes poor layer adhesion and weak parts. The 3D Printing Nerd's PETG guide covers cooling strategies well.

4. Lower the temperature if stringing is bad. Drop 5°C at a time until stringing is manageable.

5. Reduce retraction speed. 25mm/s works better than 40mm/s for PETG.

6. Enable Z-hop. 0.3-0.5mm prevents the nozzle from dragging through existing layers and creating blobs.

7. Slow down. PETG benefits from slower speeds than PLA. 40-50mm/s produces much better results than trying to print PETG at PLA speeds.

8. Get AI-tuned settings. For specific models, 3DSearch generates slicer settings that account for PETG's unique requirements based on the model geometry. This is especially helpful for parts with overhangs or bridges where PETG's reduced cooling creates challenges.

Final Rankings

1. Overture PETG — Best value, great all-rounder
2. Polymaker PolyLite PETG — Best surface quality
3. eSUN PETG — Most beginner-friendly, strongest raw tensile
4. Prusament PETG — Best consistency, layer adhesion, and QC
5. Hatchbox PETG — Reliable and predictable
6. Sunlu PETG — Best transparent options
7. Inland PETG — Budget functional printing
8. Amazon Basics PETG — Cheapest with trade-offs

Final Thoughts

PETG brand selection matters more than PLA brand selection because the material is more demanding and the differences between formulations are more pronounced. Premium PETG (Prusament, Polymaker) strings less, adheres better between layers, resists moisture degradation longer, and produces cleaner surfaces.

That said, even budget PETG produces strong, functional parts when properly dried and printed with optimized settings. The brand you use matters, but your settings and filament storage practices matter more. Dry your filament, use a textured bed, and tune your temperature — those three things improve PETG print quality more than any brand upgrade.

For most users, Overture PETG hits the ideal balance of quality, reliability, and price. Grab a roll, dry it properly, and you will have strong, heat-resistant parts that PLA simply cannot deliver.

Happy printing!
