Prusament PETG
Manufactured by Prusa Polymers
Quick Summary
This Prusament PETG review carries over the same headline as its PLA sibling: ±0.02 mm diameter tolerance and a scannable QR code linking to each spool’s measured batch data. PETG is inherently fussier than PLA, and the consistency here is exactly what takes the frustration out of it.
Print Settings
Prusa specifies 250 ± 10 °C nozzle and 80 ± 10 °C bed, with cooling around 50% on a satin or powder-coated sheet. Start at 250 °C / 85 °C. The modest fan speed is deliberate — too much cooling weakens PETG layer bonds, and Prusament’s flow consistency makes it easy to find a clean retraction setting.
Print Quality
Layer and bed adhesion are excellent, producing strong, watertight functional parts. Because diameter barely varies, walls come out uniform and dimensional accuracy is good for a PETG. Stringing, the usual PETG complaint, is well controlled once tuned — and easier to tune than with inconsistent budget spools.
Where It Falls Short
It is expensive for PETG, and like all PETG it is hygroscopic — leave it out and stringing returns until you dry it at ~65 °C. The strong bed adhesion also means you want a release agent on smooth sheets to avoid chipping.
Verdict
When a PETG part has to be both tough and dimensionally right, Prusament PETG is the safe choice. For bulk or non-critical prints, cheaper PETG stretches your budget further.
- Prusament PETG vs overture petg — Overture PETG is far cheaper and perfectly capable once tuned; Prusament's tighter tolerance and traceability justify the premium for accuracy-critical functional parts.
- Prusament PETG vs esun petg — eSUN PETG is a solid budget option; Prusament prints more consistently spool-to-spool and strings less after tuning.
What temperature should I print Prusament PETG at?
Prusa specifies 250 ± 10 °C at the nozzle with an 80 ± 10 °C bed and the cooling fan around 50%. 250 °C / 85 °C on a textured or satin sheet is a reliable starting point.
Is Prusament PETG less stringy than cheaper PETG?
Generally yes. The tight diameter control and consistent formulation make retraction tuning easier, so once dialed in it strings less than most budget PETG — though, like all PETG, it benefits from drying.
What is the QR code on the spool for?
Each Prusament spool has a QR code linking to the exact measured data for that batch — diameter readings and roundness — so you know precisely what you are printing.
