Prusament PETG 1.75mm 1kg vs Polymaker PolyLite PETG Filament

Both are 1.75 mm PETG on 1 kg spools, but they target different printers. Prusament PETG is the tighter, more consistent spool: ±0.015 mm tolerance, low ovality and a documented standard deviation, which matters on slower, precise machines and for parts that must fit. PolyLite PETG is the faster formula, rated to 300 mm/s and over 500 mm/s with high-flow nozzles, with strong layer adhesion and low warping. Owners of both report reliable feeding; Prusament is known for spool-to-spool consistency, while PolyLite is known for speed and a wide color range.

  • Choose the Prusament PETG if you print at moderate speeds on a stock machine and want the most dimensionally consistent filament, with published tolerance data and a slightly heavier net spool.
  • Choose the PolyLite PETG if you run a fast or high-flow printer and want a formula built for speed, broad color choice and easy AMS feeding.

What reviewers say

Prusament PETG 1.75mm 1kg

Owners of Prusament PETG generally report consistent diameter, reliable extrusion and strong, durable prints. Complaints center on stringing, bed adhesion that is sometimes too strong on smooth PEI, and the need to dry the spool.

What people mention
  • Diameter consistencyPraisedUsers say the filament measures close to 1.75 mm and extrudes evenly.
  • StringingCriticisedReviewers report hairs and blobs unless retraction and temperature are tuned.
  • Bed adhesionMixedPrints stick well, but some say they stick too hard to smooth PEI.
  • StrengthPraisedOwners describe tough, durable parts with good layer bonding.

Polymaker PolyLite PETG Filament

Owners of PolyLite PETG generally report clean prints, good layer adhesion and low warping once settings are dialed in. The recurring complaint is moisture: filament that has sat open strings heavily and needs drying.

What people mention
  • StrengthPraisedOwners say parts come out tough and hold up in functional use better than PLA.
  • WarpingPraisedReviewers report little lifting on large flat prints compared with ABS.
  • StringingCriticisedMany say the filament strings and oozes, especially after it has been left out.
  • MoistureCriticisedBuyers note it absorbs water quickly and needs drying to print cleanly.

Questions and answers

Which is better for fast printing?
PolyLite PETG. It is formulated for high flow and rated to 300 mm/s, or over 500 mm/s with a high-flow nozzle. Prusament PETG is not rated for those speeds.
Which has more consistent diameter?
Prusament PETG. It publishes ±0.015 mm tolerance, 4.3553 µm standard deviation and 1.9% ovality. Polymaker does not publish comparable figures for PolyLite.
Is Prusament worth stepping up to over PolyLite?
If your prints are slow and fit matters, yes: the tighter tolerance and extra 53 g help. If you print fast or want color choice, PolyLite gives more for the job.
Which handles heat better?
PolyLite PETG lists about 70 °C heat deflection, and its page cites 80 °C heat resistance. Prusament does not publish an HDT, so treat both as PETG-level, not for hot environments.
Do either need drying?
Both benefit from dry storage. Polymaker explicitly warns PolyLite is very hygroscopic and ships it with a desiccant bag; dry Prusament too if you see stringing or popping.
Will both work in an AMS or multi-material setup?
Polymaker states PolyLite works with AMS and multi-material systems. Prusament is a standard 1.75 mm spool and generally feeds fine, but Polymaker makes the compatibility claim explicitly.
