1 / 7SUNLU PETG 2.0 Red 3D Printer Filament, 1.75 mm
SUNLU PETG 2.0 is a red 3D printer filament for buyers seeking a PETG material with manufacturer-claimed reduced moisture uptake and stringing. Its listed 1.75 mm diameter and 1KG spool make it relevant for compatible FDM printing, while the claimed toughness and print behaviour are not independently verified here.
At a glance
- The listing describes a PETG 2.0 reformulation intended to reduce moisture sensitivity, stringing and fuzzy surfaces.
- SUNLU claims the filament can remain printable after three days open at room temperature without emergency drying.
- The listing claims a notched impact strength of 5.196 KJ/m², compared with 3 KJ/m² for classic PETG.
- Each spool is claimed to be vacuum-sealed with desiccant.

Pros
- The stated 1.75 mm diameter and ±0.03mm tolerance provide useful compatibility and dimensional details for printer setup.
- A 1KG red spool suits buyers planning larger batches or multiple prints in one colour.
- The lower moisture-uptake claim may be useful for users who do not routinely store filament in a dry box.

What to know before buying
- The claimed moisture tolerance, reduced stringing, impact strength and printability are manufacturer statements, not independently verified performance results. Confirm that 1.75 mm filament is compatible with your printer and follow the printer's PETG settings.
Who is it for?
A good fit for
- FDM 3D printer owners who need red PETG filament with a listed 1.75 mm diameter.
- Buyers printing functional parts who are interested in the manufacturer's higher-impact-strength claim.
- Users who want a 1KG spool and prefer a filament claimed to be less sensitive to room humidity.
Less suited to
- Anyone needing independently verified print-quality or impact-test results.
- Users whose printer requires a different filament diameter or material.

Aggregate ratings are mostly in the five-star category, with some lower ratings also present. This offers a broadly favourable but not unanimous signal for the filament, without showing what buyers liked or disliked. The ratings do not verify the listing's claims about moisture resistance, stringing or impact strength.
Frequently asked questions
What material is this filament?
The listing identifies it as SUNLU PETG2.0 Filament, a PETG material for 3D printing.
What is the listed filament diameter?
The listed diameter is 1.75 Millimetres. Check that your printer accepts this size.
Does the listing say it needs drying before printing?
SUNLU claims lower water uptake and says it can print cleanly after three days open at room temperature without emergency drying. This performance claim is not independently verified.
How strong is the filament?
The listing claims a notched impact strength of 5.196 KJ/m² and compares it with 3 KJ/m² for classic PETG. Treat those as manufacturer claims rather than verified test results.
