Heat, strength and drying, as each maker states them

X-Y figures come from specimens printed flat. Z figures measure the bond between layers, which Polymaker labels layer adhesion.

1. Polymaker PETG: best overall

Polymaker PETG is the successor to PolyLite PETG, which Polymaker says will be discontinued. It is the most thoroughly documented spool in this list. Polymaker’s product page lists ISO-method results for density, tensile and bending strength, impact, glass transition, Vicat softening and heat deflection, all on 100% infill specimens.

The figure that matters most for functional parts is layer strength. Polymaker lists 45.71 MPa tensile strength between layers (Z) against 47.96 MPa along them (X-Y), so its published layer bond is close to its in-plane strength. Its heat deflection temperature is 69 °C at 0.45 MPa.

Polymaker gives a 240–260 °C nozzle range, a 60–70 °C bed and up to 300 mm/s on a standard nozzle (500 mm/s or more with a high-flow nozzle). It says an enclosure is not needed. It also says the filament works with AMS and other multi-material systems. Polymaker calls the material “very hygroscopic” and packs it in resealable vacuum barrier bags. Its product page gives two different drying settings (60 °C for 6 hours in one place, 65 °C for 4 hours in another), so check the label on your spool.

Choose it if you want one PETG for brackets, fixtures and enclosures on a modern printer. Skip it if your printer runs near Elegoo’s 600 mm/s rating and you want a spool rated that high.

2. Elegoo Rapid PETG: best for fast printers

Elegoo Rapid PETG has the highest speed figure here: Elegoo says it supports 30 to 600 mm/s. It also has the tightest published diameter tolerance, ±0.02 mm, matched only by SUNLU in this list.

Elegoo’s spec table lists a 240–270 °C nozzle range, a 65–75 °C bed, a nozzle of 0.2 mm or larger, and no enclosure requirement. It recommends glue on the build plate and lists a 72 °C heat deflection temperature at 0.45 MPa. Its published layer (Z) tensile strength is 28 ± 3 MPa against 42 ± 2 MPa along the layers, a wider gap than Polymaker’s.

Elegoo is strict about moisture. It lists drying before use as required, at 60 ± 5 °C for 8 hours, and gives a printing and storage humidity of 20% RH or lower, sealed with desiccant. Each spool ships vacuum-sealed with desiccant.

Choose it if your printer and profile actually run at high speed. Our Elegoo Rapid PETG review covers where that speed helps. Skip it if you have no dryer or sealed storage.

3. eSUN PETG: best for outdoor parts

eSUN PETG is the pick for weather-exposed parts. eSUN’s data sheet answers “YES” for both UV resistance and water repellency, and eSUN’s own store lists weather resistance and waterproofing among its features. The store offers it in solid and translucent colors.

It is a standard-speed PETG. eSUN’s July 2025 data sheet gives a print speed under 150 mm/s, a 230–260 °C nozzle range, a 75–90 °C bed and drying at 60 °C for more than 8 hours; if your spool’s label differs, follow the label. eSUN’s store lists a ±0.05 mm diameter tolerance. The data sheet also lists a heat deflection temperature of 64 °C at 0.45 MPa (GB/T 1634), the lowest published figure in this list.

Choose it if the part lives outdoors or near water and your printer runs at ordinary speeds. More detail is in our eSUN PETG review . Skip it if the part sits close to warm motors or electronics.

4. SUNLU PETG: best for 2.85 mm printers and spool sizes

SUNLU PETG is the only pick here whose maker lists 2.85 mm and 3.00 mm versions alongside 1.75 mm. SUNLU also lists 0.25, 0.5, 1, 2, 3 and 5 kg weights, which helps if you want a small sample spool or a large refill for a long production run. The linked Amazon listing is the 1.75 mm, 1 kg black spool, so check diameter and weight before you buy a different size.

SUNLU publishes a 1.75 ± 0.02 mm diameter tolerance, a 240–260 °C nozzle range at up to 300 mm/s, and a 60–70 °C bed. It also gives 0.8–1.2 mm retraction at 30–40 mm/s. Its 70 ± 5 °C heat deflection figure is given without a test load, so it does not compare directly with the others.

Choose it if you run a 2.85 mm machine or want one PETG line in several spool sizes. Skip it if you want the fullest published test data, which Polymaker gives.

5. Overture High Speed PETG: best for color choice

Overture High Speed PETG is listed in 24 colors on Overture’s store, including transparent, transparent red, transparent green and transparent blue. That makes it the easiest pick here for matching a color or printing light-transmitting parts. The linked Amazon listing is the 1 kg Light Gray spool.

Overture gives a 230–260 °C nozzle range and a 65–70 °C bed, with the cooling fan on. Its drying advice is 60 °C for 5 hours, and it warns that drying longer can make the filament brittle. Unopened spools have a 1-year shelf life with proper storage. Overture does not publish a speed figure or diameter tolerance on the product page.

Choose it if color matters as much as toughness. Our Overture PETG review covers where it fits. Skip it if you need published heat-deflection data for a load-bearing part.

PETG pros and cons

The makers above agree on the main trade-off.

• Tough and water resistant. eSUN’s store lists its PETG as waterproof, high-toughness and chemical-resistant. Polymaker says its PETG is less brittle and more impact-resistant than PLA.
• Moderate heat resistance. Published heat deflection figures sit between 64 and 72 °C at 0.45 MPa. That is enough for many indoor functional parts, but not for parts that run hot. For those, compare PETG vs ASA and PETG vs ABS .
• No enclosure needed. Polymaker and Elegoo both say their PETG prints without an enclosure.
• Moisture-sensitive. Polymaker warns that wet PETG causes stringing and poor surfaces, and four of the five makers here publish a drying setting.
• Sticks hard to smooth plates. Polymaker recommends a glue-stick release layer on smooth PEI or glass.

If your parts are decorative or quick prototypes, PLA is still the simpler material. See PLA vs ABS vs PETG for the side-by-side.

How to choose PETG filament

Match the speed rating to your printer. PETG now comes in standard and high-speed versions. eSUN rates its PETG under 150 mm/s, Polymaker (on a standard nozzle) and SUNLU go to 300 mm/s, and Elegoo goes to 600 mm/s. On a fast printer, a spool rated under 150 mm/s means slowing your profile to the maker’s limit.

Use the maker’s temperature range, not a generic profile. Published nozzle ranges here run from 230 °C (Overture, eSUN) to 270 °C (Elegoo), and bed ranges from 60 °C (Polymaker, SUNLU) to 90 °C (eSUN). Overture says generic PETG-HF profiles in Bambu Studio can cause adhesion, stringing and layer-bonding failures with its filament. Start from the brand’s own preset or label.

Plan drying by brand. Drying advice differs: 60 °C for 5 hours with a warning not to go longer (Overture), 60 °C for more than 8 hours (eSUN), and 60 ± 5 °C for 8 hours (Elegoo). A dryer that holds 60 °C covers all three. Our filament dryer roundup compares options.

Check heat and layer strength for load-bearing parts. For a bracket that takes load across its layers, compare the Z (between-layer) figures where the maker publishes them. For parts near warm electronics, compare heat deflection at the same 0.45 MPa load.

Check diameter and spool fit. Confirm 1.75 mm or 2.85 mm before ordering, and confirm the spool fits your holder, AMS or dry box.

Stringing, warping and moisture claims

Stringing and webbing. PETG leaves more ooze than PLA during travel moves, so webbing shows first on text, small islands and open cutouts. Moisture makes it worse, so keep opened spools sealed or dried per the maker’s instructions. Bowden machines have a longer filament path and tolerate retraction error less than direct drive, a brand change can need a retune, and too much cooling can weaken layer bonding while too little leaves soft strings. Polymaker’s advice for stringing is to dry the filament first, then lower the nozzle temperature within its range, then tune retraction. An unchanged PLA profile, or fixing everything with fan speed, is a common mistake.

Warping in an enclosure. An enclosure changes the failure mode rather than removing it: it reduces drafts, but a hot closed chamber can keep wide, flat parts soft while they contract. Large flat or fit-critical parts benefit from chamfers, fillets or a brim, and from a printer that shows or vents chamber temperature.

Moisture claims. Look for a moisture-absorption figure with the test standard named, such as ISO 62 or ASTM D570; a claim with no test method does not compare between brands. Batch or lot identification helps if you reorder a color. Specialty and filled blends can change finish and feel but do not remove the need for dry storage and tuning, and carbon-fiber or glass-filled PETG is not the most forgiving starting point. If a listing omits temperature, drying, cooling or storage guidance, that tuning burden lands on you. For fine decorative detail, PLA or PLA+ is the lower-risk choice.

Who should skip PETG

Skip PETG if your printer still fights first layers. PETG adds a hotter nozzle, a stickier bed and moisture control to the problems you already have, and PLA does most beginner jobs with less setup.

Skip it for display models that never leave a shelf, where its toughness brings no benefit. Skip it, too, for parts that sit above the roughly 64 to 72 °C heat deflection range these makers publish.

Frequently Asked Questions

Does PETG print harder than PLA?

It asks for more setup. PETG makers publish higher nozzle temperatures than PLA, ask for a heated bed, and warn that wet PETG strings. PLA prints with less setup and fewer bed-surface conflicts.

What bed surface works best for PETG?

Polymaker recommends a textured PEI plate for its PETG and a thin layer of glue stick as a release layer on smooth PEI or glass, because PETG can bond too strongly to those surfaces.

Does PETG need to be dried before printing?

Follow the label on your spool. Elegoo lists drying before use as required for Rapid PETG and Overture says to always dry its PETG first, while Polymaker says to dry only if the filament has absorbed moisture. All three warn that wet PETG prints poorly.

Is PETG strong enough for functional parts?

Yes for brackets, clips, enclosures and jigs that see repeated handling. The heat deflection figures these makers publish sit around 64 to 72 °C at 0.45 MPa, so parts that run hotter than that belong in ASA, ABS or another higher-temperature material.
