Best PETG Filament Brands Tested in 2026

Not all PETG is created equal. I've had spools that print like butter on the first try and spools that string, blob, and clog no matter what settings I throw at them. After burning through too much money on mystery-brand PETG from Amazon, I decided to do an actual controlled test.

I printed the same five test models — a benchy, a calibration cube, a thin-wall vase, a mechanical hinge, and a bridging torture test — on each of five popular PETG brands. Same printer (Ender 3 V3, all-metal hotend), same slicer profile, same ambient temperature (22°C). The only thing I changed between brands was nozzle temperature, dialed in per the manufacturer's recommendation.

The Brands Tested

• Hatchbox PETG — $22/kg (Amazon)
• eSun PETG — $19/kg (Amazon)
• Overture PETG — $18/kg (Amazon)
• Polymaker PolyLite PETG — $26/kg (Polymaker.com)
• Prusament PETG — $30/kg (Prusa3D.com)

All tested in the same color (black or dark gray) to keep comparisons fair. Color additives can change flow characteristics, so comparing clear PETG to opaque isn't valid.

1. Hatchbox PETG — Best All-Rounder

Hatchbox has been a community staple for years, and the PETG holds up. At $22/kg, it sits in the middle of the price range and delivers consistently good results.

Optimal settings: 240°C nozzle, 80°C bed, 40 mm/s speed. Retraction at 5 mm, 35 mm/s.

The diameter tolerance was solid — I measured 1.74-1.76 mm across 10 random spots (advertised 1.75 mm ± 0.03 mm). Stringing was moderate — noticeable on the benchy chimney but easily cleaned up with a heat gun at 200°C for 3 seconds. Layer adhesion was excellent. The mechanical hinge survived 500+ cycles before I stopped counting.

The bridging performance surprised me. Clean bridges up to 40 mm with minimal sag. At 60 mm, some drooping appeared but the bridge still held structural integrity.

2. eSun PETG — Best Budget Pick

At $19/kg, eSun is the cheapest brand in this test. And for functional parts where cosmetics don't matter, it's genuinely hard to beat.

Optimal settings: 235°C nozzle, 80°C bed, 35 mm/s speed. Retraction at 5 mm, 30 mm/s.

eSun PETG runs slightly wetter than the others — I noticed more stringing at the same retraction settings. Dropping speed to 35 mm/s and lowering retraction speed helped. Surface finish was good but not as smooth as Hatchbox or Polymaker. Dimensional accuracy was within 0.15 mm on the calibration cube.

The standout was value. For bracket prints, tool organizers, and under-desk cable management — parts nobody sees — eSun gets the job done at the lowest cost per gram.

3. Overture PETG — Most Consistent

Overture ships on a nice resealable bag with a desiccant pack, and that attention to packaging translates to the filament itself. At $18/kg, this is actually the cheapest brand tested and arguably the best value.

Optimal settings: 238°C nozzle, 82°C bed, 40 mm/s speed. Retraction at 4.5 mm, 35 mm/s.

Diameter consistency was the best of the budget options — 1.74-1.75 mm across all measurement points. What impressed me most was batch consistency. I've now used four spools of Overture PETG over 6 months, and every spool printed identically with the same settings. That matters when you're doing production runs and don't want to re-tune every time you swap spools.

Stringing was low for PETG — comparable to Hatchbox with slightly less cleanup needed. Layer adhesion was strong. Bridging was acceptable at 30-35 mm.

4. Polymaker PolyLite PETG — Best Surface Finish

Polymaker charges a premium at $26/kg, and you're paying for surface quality. The prints from this filament look noticeably better than the budget brands — smoother surfaces, less visible layer lines, and almost no stringing with the right settings.

Optimal settings: 245°C nozzle, 85°C bed, 40 mm/s speed. Retraction at 4 mm, 40 mm/s.

The higher nozzle temp surprised me — most PETG brands print best at 235-240°C, but Polymaker's formulation clearly wants more heat. At 240°C, I got slight underextrusion. At 245°C, perfect flow. The vase mode print was the best of the five brands — translucent, smooth, no visible layer separation.

If you're printing parts that need to look good — customer-facing products, display items, or gifts — Polymaker is worth the extra cost.

5. Prusament PETG — Tightest Tolerances

At $30/kg plus shipping from the Czech Republic, Prusament is the most expensive PETG on this list by a wide margin. Is it worth it? For most people, no. For precision work, absolutely.

Optimal settings: 240°C nozzle, 85°C bed, 45 mm/s speed. Retraction at 3.5 mm, 40 mm/s.

Prusament's advertised tolerance is ± 0.02 mm. My measurements confirmed it — I got 1.747-1.753 mm across 20 measurement points. That's insanely consistent. This translates to dimensional accuracy on prints that's nearly impossible to achieve with wider-tolerance filaments. My calibration cube measured 20.02 x 20.01 x 19.98 mm — basically perfect.

Stringing was the lowest of all five brands. Bridging performance was excellent — clean bridges at 50 mm with no sag. The only downside besides price is color selection — Prusament offers fewer colors than competitors.

The Rankings

• Best overall: Hatchbox PETG ($22/kg) — best balance of price, quality, and reliability
• Best budget: Overture PETG ($18/kg) — cheapest and most batch-consistent
• Best surface quality: Polymaker PolyLite PETG ($26/kg) — smoothest prints, least stringing
• Best precision: Prusament PETG ($30/kg) — tightest diameter tolerance, best dimensional accuracy
• Best value for functional parts: eSun PETG ($19/kg) — cheap and strong, less pretty

Settings Baseline for Any PETG

If you're trying a new PETG brand and want a starting point, use these settings and adjust from there:

• Nozzle: 240°C (then adjust ± 5°C based on results)
• Bed: 80°C on glass, 85°C on PEI
• Speed: 40 mm/s (safer starting point than PLA's 50-60 mm/s)
• Retraction: 5 mm at 35 mm/s (Bowden) or 2 mm at 30 mm/s (direct drive)
• Fan: 30-50% (lower than PLA — PETG likes warmth)
• First layer: 235°C nozzle, 10 mm/s speed, 0 fan

To calculate the actual per-print cost with any of these brands, use our filament cost calculator — just enter the spool price and your model's estimated weight to see the real number.

At the end of the day, any of these five brands will serve you well. The differences show up at the margins — tighter tolerances, smoother surfaces, lower stringing. If you're printing functional parts, buy Overture or eSun and use the savings for more spools. If you're printing display pieces or precision parts, Polymaker or Prusament are worth every penny.
