Overture PETG vs eSUN PETG

Who this comparison is for

This page is for anyone choosing between these two specific spools: Overture PETG in Black and eSUN PETG in Black, both 1.75 mm and 1 kg. Overture's store calls this product "Overture High Speed PETG" and lists Black, 1.75 mm, 1 kg as SKU VFEBLK17511, while its data sheet and wiki call it "OVERTURE PETG." eSUN's product page lists the 1.75 mm diameter and a "Net Weight" of "1KG/Spool," and sells PETG in solid and translucent colors. The Amazon listings we link report model OVPETG175 for Overture and PETG175SB1A for eSUN. That's our listing data, not something either maker's page shows, so check the color and weight on the listing before you buy. If you're still deciding on a material, start with PLA vs PETG or PETG vs ABS.

How we compared them

This is a research-based comparison. Every figure below comes from the makers' own product pages, data sheets, wiki, and FAQ, listed in the sources. We haven't tested either filament, so nothing here is a measured result of ours. Where a maker describes its own product, such as Overture's "Odorless" or eSUN's "free from warping or cracking," we label it as the maker's claim.

We only put numbers side by side where both makers publish the same kind of value under the same test conditions. Print settings such as nozzle and bed temperature are each maker's guidance, so they sit in the table. The test figures don't qualify. The two makers printed their test bars under different settings, used different heat tests, and used different impact tests, so we list each maker's figures separately.

Side-by-side specs

Temperatures, bed, and fan

The nozzle ranges match on the data sheets, at 230–260 °C, though eSUN's product page starts higher, at 240 °C. The beds don't overlap at all. Overture's 65–70 °C range ends 5 °C below where eSUN's 75–90 °C range starts. If you switch between the two, change the bed temperature, not just the filament profile.

• Overture PETG. The data sheet recommends "OVERTURE Build Surface, Textured PEI," and lists the surface treatment as "None, Applying PVA glue to the build surface," without saying when to use glue. The FAQ on the product page says that if PETG warps or won't stick, "try using a suitable bed surface like glass or PEI, possibly applying a light adhesive like glue stick or hairspray," and print the first layers slower. On cooling, the same FAQ says a fan reduces stringing "but be aware that it may weaken layer adhesion," and that "the initial layer should have minimal cooling (around 0% or very low)."
• eSUN PETG. The data sheet lists a PEI build platform at 75–90 °C and the fan at 100%. The product page lists a heated bed as "Required." eSUN says its PETG "requires no heated enclosure, and is free from warping or cracking," which is eSUN's claim, with no warping test published.

Overture's FAQ also warns about Bambu Studio's Generic PETG-HF profile, saying failures "often occur due to a mismatch" with what Overture PETG needs, and that "Generic profiles may run too cool or use suboptimal cooling for PETG." If you print on a Bambu Lab machine, set the nozzle within Overture's 230–260 °C range rather than relying on that profile.

Speed: four figures, none a measured race

The two makers each publish more than one speed figure.

• Overture PETG. The data sheet, the spec panel, and the FAQ give a printing speed below 300 mm/s, and the data sheet says its settings are "Based on 0.4 mm nozzle." The wiki's recommended settings give 90 mm/s. Overture doesn't explain the difference.
• eSUN PETG. The data sheet gives below 150 mm/s, and the product page gives the same figure as a "high-speed printing parameter." The data sheet's printing tips also suggest you "appropriately reduce the printing speed to achieve the best printing effect."

Neither maker says what layer height or line width its figure assumes, so these are each maker's guidance, not a speed test. Overture's own test bars were printed at 45 mm/s. Our stringing guide covers what to change if faster PETG starts to string.

Heat and strength figures: listed separately

These can't be set side by side. Both makers tested printed bars at 100% infill, but under different settings. Overture printed its bars at a 240 °C nozzle, 45 mm/s, and an 80 °C bed, and conditioned them for 24 hours. That bed is above Overture's own recommended 65–70 °C, and Overture doesn't explain why. eSUN printed its bars on a Bambu Lab P1S with a 0.4 mm nozzle at a 260 °C nozzle, an 80 °C bed, and the fan at 100%. Overture tested to ISO and GB/T standards, and eSUN to GB/T standards only. The heat tests differ too: Vicat softening for Overture and heat distortion for eSUN. The impact tests differ as well: Charpy for Overture and Izod for eSUN.

Overture PETG (TDS V5.2, printed bars at 100% infill)

• Vicat softening temperature: 75 °C (ISO 306, GB/T 1633)
• Young's modulus: 2311.1 ± 92.4 MPa X-Y (ISO 527, GB/T 1040)
• Tensile strength: 47.9 ± 4.8 MPa X-Y, 45.7 ± 1.7 MPa Z (ISO 527, GB/T 1040)
• Elongation at break: 9.3 ± 6.5% X-Y, 3.5 ± 2.2% Z (ISO 527, GB/T 1040)
• Bending strength: 80.1 ± 3.5 MPa X-Y, 57.6 ± 5.6 MPa Z (ISO 178, GB/T 9341)
• Bending modulus: 2277.3 ± 198 MPa X-Y, 1958.72 ± 126.4 MPa Z (ISO 178, GB/T 9341)
• Charpy impact strength: 20.2 ± 3.4 kJ/m² X-Y, 15.7 ± 3.9 kJ/m² Z; notched 4.85 ± 0.35 kJ/m² X-Y (ISO 179, GB/T 1043)
• Density: 1.3 g/cm³ at 20.7 °C (ISO 1183, GB/T 1033)
• Melt index: 8.8 g/10 min at 240 °C and 2.16 kg

eSUN PETG (TDS V2.0, July 2025, printed bars at 100% infill)

• Heat distortion temperature: 64 at 0.45 MPa, unit not stated (GB/T 1634); the product page lists it as 64 °C
• Tensile strength: 34.77 MPa X-Y, 28.65 MPa Z (GB/T 1040)
• Elongation at break: 5.15% X-Y, 3.91% Z (GB/T 1040)
• Flexural strength: 41.9 MPa X-Y, 39.9 MPa Z (GB/T 9341)
• Flexural modulus: 1228.33 MPa X-Y, 1276.45 MPa Z (GB/T 9341)
• Izod impact strength: 4.86 kJ/m² X-Y, 1.78 kJ/m² Z (GB/T 1843), notched or unnotched not stated
• Density: 1.27 g/cm³ (GB/T 1033)
• Melt flow index: 20, at 250 °C and 2.16 kg (GB/T 3682)

Overture's heat figure needs care, because its own documents disagree:

The wiki also gives a density of 1.25 g/cm³ against the data sheet's 1.3. Overture doesn't explain either difference. eSUN's 64 °C is a heat distortion figure at the lighter 0.45 MPa load, a different test from Vicat softening, so the gap between the two makers doesn't show which spool handles heat better. For a part that will sit near heat, plan around the lowest figure each maker publishes. Our parts deforming in heat guide covers what to try instead.

Drying and storage

Both makers say to dry PETG at 60 °C before printing, and they differ on the time.

• Overture PETG. The spec panel says "60°C for 5 hours (Do not exceed recommended time; over-drying can cause filament brittleness)." The FAQ on the product page says "PETG is sensitive to moisture," and to store it "in a sealed container with desiccants." Overture's drying guide rates PETG's moisture sensitivity "High." Its product page gives "a 1-year shelf life for unopened spools (proper storage required)."
• eSUN PETG. The data sheet lists drying at 60 °C for more than 8 hours, and the product page says "Dry at60℃/>8h." A note on the product page says "To prevent stringing, oozing, and nozzle buildup, PETG should be dried at 60°C for 8 hours." eSUN doesn't warn against over-drying.

Use the setting for your own spool, and check that the spool can take the heat before drying on it, since neither maker publishes a temperature rating for its spool. Our wet filament guide and filament dryer vs dry box guide cover the options.

Spools and multi-material feeders

Overture's site-wide FAQ says it "uses cardboard spools as part of our environmental protection efforts," and suggests "a reusable spool adapter designed for cardboard spools" if you prefer plastic. Its PETG wiki page gives the spool as 200 mm across and 65.6 mm high, with a 55 mm hub and an empty weight of about 147 g.

eSUN doesn't state the spool's material or size on its PETG product page or data sheet. The Amazon listing we link describes a black spool about 8 in across and 2.5 in wide, with a 2.05 in hub hole. That's our listing data, not eSUN's. Neither maker mentions the AMS or any other feeder on the pages we checked, so we make no compatibility claim for either. Our AMS filament compatibility guide covers spool sizes and adapters.

What each maker says it's for

• Overture PETG. Overture says it "combines the ease of PLA with the strength and impact resistance of ABS," and lists "garden fixtures, automotive components, and functional prototypes" among outdoor uses, citing "excellent weather-resistance and water-resistant properties." Its wiki rates print difficulty "Low. Great for beginners," lists odor as "Odorless," and lists cosplay props, garden tools, toys, brackets, and enclosures. Those are Overture's claims.
• eSUN PETG. eSUN says it "combines PLA's easy printing with ABS's toughness," and that its "new formula handles outdoor conditions with ease." The data sheet lists UV resistance as "YES," and the product page says "Retains Color Without Fading." eSUN lists prototyping, outdoor decoration, and household items. Those are eSUN's claims, with no weathering test published.

• You want the UV resistance eSUN lists on its data sheet, knowing it publishes no weathering test.

Safety and limits

How this page was checked

Every temperature, speed, drying setting, spool detail, and test figure above comes from the manufacturer documents in the sources section, retrieved on 2026-10-13. We haven't printed with either filament for this page, so nothing here is a measured result of ours. Both makers disagree with themselves in places. Overture's data sheet gives a 75 °C Vicat figure and a 1.3 g/cm³ density, while its FAQ and wiki give 85.1 °C and its wiki gives 1.25 g/cm³; its wiki's 90 mm/s speed differs from the below-300 mm/s figure elsewhere; and its test bars were printed on an 80 °C bed, above its own recommended range. eSUN's product page starts its nozzle range at 240 °C against the data sheet's 230 °C. We've reported each figure with where it appears. eSUN's product page labels its density figure "(unit to be confirmed)," so we've used the data sheet's g/cm³. We found no spool specification, diameter tolerance, or retraction settings for eSUN PETG on its product page or data sheet. Values vary by color and revision, so check the current data sheet for your spool. Read more in our editorial standards and affiliate disclosure.
