eSUN PETG Filament 1.75mm 1kg vs Prusament PETG 1.75mm 1kg

Buy the Prusament PETG if print consistency matters most: its ±0.015 mm tolerance, published standard deviation and ovality figures, and 1053 g of filament are the tightest specs in this pair, and owners and reviewers consistently rate it among the most reliable PETG spools. Buy the eSUN PETG if you want a proven, widely used PETG in a broad color range and don't need the tighter diameter control. Both are tough, weather-resistant PETG with similar temperature needs; Prusament's edge is dimensional accuracy and documentation, eSUN's is availability and color choice.

  • Choose the eSUN PETG if you want a dependable everyday PETG in a wide range of colors and easy sourcing.
  • Choose the Prusament PETG if tight diameter tolerance and published quality data matter for consistent, repeatable prints.

What reviewers say

eSUN PETG Filament 1.75mm 1kg

Owners of eSUN PETG mostly praise consistent diameter, tidy winding and strong, well-bonded prints. Complaints center on stringing, oozing and bed adhesion that is sometimes too strong, plus the tuning PETG always demands.

What people mention
  • StringingCriticisedOwners report stringing and fine wisps between parts unless retraction and temperature are dialed in.
  • Print strengthPraisedParts are described as tough and impact-resistant, with layers that hold together well.
  • WindingPraisedThe spool is reported as evenly wound with no tangles or overlaps during long prints.
  • Bed adhesionMixedFirst layers stick reliably, but some users say prints can fuse to smooth PEI or glass and need a release agent.

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.

Questions and answers

Which is better for detailed, functional parts?
Prusament PETG. Its ±0.015 mm tolerance and published ovality and standard deviation figures give more consistent extrusion, which shows on fine features and mating parts.
Does tighter tolerance really matter?
For most toys and containers, no. For multi-part assemblies, repeated production runs or fine detail, yes. Prusament's tighter spec reduces flow variation between spools.
Which has more color choices?
eSUN. It ships in a broad color range, while Prusament's PETG lineup is smaller and rotates.
Do they print at the same settings?
Close but not identical. Prusament specifies 240-260 °C extruder and 70-90 °C bed. eSUN prints well in the usual PETG range, around 230-250 °C, with a heated bed.
Is Prusament worth stepping up to?
If you print functional parts or sell prints, yes: the tighter tolerance and published QC data reduce failed spools. For casual printing, eSUN covers the same material properties.
Which lasts longer on the spool?
Both are PETG and absorb moisture similarly. eSUN ships with a desiccant bag; store either sealed and dry. Prusament gives slightly more filament per spool.
