OVERTURE PETG is the spool we reorder more than any other. It holds a tight ±0.02 mm tolerance, feeds reliably in our AMS, and prints the same color after color. If you run a fast printer, ELEGOO Rapid PETG is rated far faster than standard PETG. Need clear parts? Use OVERTURE’s transparent PETG. Printing anything that touches food? Use a certified food-grade PETG, not a regular spool.

After PLA, PETG is what our makers print most, and it goes almost entirely into functional parts: cases and enclosures, mounts, brackets and other pieces that get handled, warm up a little, or get screwed together. That’s the job PETG is good at.
| OVERTURE PETG | SUNLU PETG | ELEGOO Rapid PETG | |
|---|---|---|---|
| Diameter tolerance | ±0.02 mm | ±0.02 mm | not stated |
| Speed rating | 30–300 mm/s | 50–200 mm/s | up to 600 mm/s |
| Nozzle / bed (maker’s) | 230–260 °C / 65–70 °C | 240–260 °C / 60–70 °C | not stated; start from your slicer’s high-speed PETG profile |
| Best for | Everyday functional parts, AMS | Fewer strings out of the bag | Printers that run at top speed |
Our take: OVERTURE is the one we keep reordering in every color. SUNLU is a good second brand when stringing is your problem. ELEGOO Rapid is the one to look at if you push a fast printer to its limits. We haven’t run eSUN PETG ourselves, so it isn’t on this list.
Who it’s for: anyone who wants one PETG that just works, from brackets to enclosures.
What you get: ±0.02 mm tolerance and neat winding, with OVERTURE’s settings of 230–260 °C nozzle, 65–70 °C bed and 30–300 mm/s.
Our experience: it’s the PETG we reorder most, across more than a dozen colors, and it feeds reliably in our AMS.
Skip it if: you need certified food contact. Use the food-grade pick.
Who it’s for: Bambu Lab A1 and P1S, Creality K1, ELEGOO Neptune 4 and other fast machines, which ELEGOO lists as compatible.
What you get: a high-flow PETG that ELEGOO rates up to 600 mm/s.
Skip it if: your printer runs at normal speeds. You’re paying for flow you won’t use.
Who it’s for: light covers, display windows and see-through cases.
What you get: OVERTURE’s high-speed PETG formula in transparent.
Tip: clear parts show every flaw. Slow the outer walls and dry the spool first.
Who it’s for: anyone fighting strings and blobs.
What you get: ±0.02 mm tolerance, vacuum-sealed spools, and SUNLU’s settings of 240–260 °C nozzle, 60–70 °C bed and 50–200 mm/s.
Skip it if: you print at your machine’s top speed. SUNLU rates it to 200 mm/s, against 300 mm/s for OVERTURE and 600 mm/s for ELEGOO Rapid.
Who it’s for: cookie cutters, cups and anything that touches food.
What you get: PETG made from Eastman GN071, food-grade tested by TÜV SÜD and SGS against FDA 21 CFR 177.1630, and tested to ISO 10993 biocompatibility protocols.
Important: the filament is food-grade, but a printed part still needs care. Comfy recommends a stainless-steel nozzle and an all-metal hotend kept for food prints, because brass nozzles can contain lead, and layer lines can trap bacteria. Read our food-safe filament guide before printing kitchen items.
Who it’s for: big batches and prototypes where you’d rather not use your best spool.
What you get: ±0.02 mm tolerance, dried and vacuum-sealed with desiccant.
Skip it if: matching color across many spools matters. Stay with OVERTURE.
PETG is polyethylene terephthalate glycol, the same family of plastic as soda bottles, made easier to print. It’s tougher than PLA, handles more heat, shrugs off water and most household chemicals, and bends a little before it breaks rather than snapping. That slight give is what people mean by “flexible”, but it’s still a rigid plastic. If you need a part that really bends, use TPU (see our TPU filament guide).
| PLA | PETG | ABS / ASA | |
|---|---|---|---|
| Ease of printing | Easiest | Easy | Needs an enclosure |
| Heat resistance | Low (softens in a hot car) | Medium (about 70–80 °C) | High |
| Toughness | Brittle | Tough, bends before breaking | Tough |
| Smell | Almost none | Almost none | Strong |
Full comparison: PETG vs PLA. For heat-proof parts, see our ABS printer guide.
Standard PETG is plenty for brackets and enclosures. If you need a stiffer part, carbon-fiber-filled PETG (PETG-CF) is the next step, and for real strength makers move to polycarbonate. We run Polymaker PolyMax Tough PC for parts that take a beating. See our strongest filament guide and PCTG guide.
Both print PETG well. Start from Bambu’s PETG or PETG HF profile. In our AMS, OVERTURE PETG feeds reliably. If you want to run at full speed, pick a PETG rated for it, such as ELEGOO Rapid, rather than pushing a standard spool past its rating.
| Setting | Starting point |
|---|---|
| Nozzle | 230–250 °C (high-speed blends: up to 260 °C) |
| Bed | 65–80 °C; PEI with glue stick or a release agent |
| Speed | 40–60 mm/s standard; follow the maker’s range for high-speed PETG |
| Retraction | 0.8–1.5 mm on direct drive, 3–5 mm on Bowden |
| Cooling | 30–50% after the first layers |
| First layer | Slightly higher Z-offset than PLA. Squishing PETG makes it stick too hard and string. |
PETG takes on moisture more slowly than TPU or nylon, but a spool left open for weeks will string. We dry and store ours in a Sovol SH02 dry box, which has a one-touch PETG setting and feeds straight to the printer.
PETG starter kit
The spool and the dry box we’d buy together: OVERTURE PETG + Sovol SH02 filament dry box.
Add both to your Amazon cartAmazon shows both items for you to confirm before anything is added. Or check the Sovol SH02 on its own.
Need a tough part but don’t own a printer? Have one of our makers print it in PETG.
OVERTURE for everyday parts: it’s the PETG we reorder most. ELEGOO Rapid if you print at high speed. Comfy Materials for food contact.
Both hold ±0.02 mm. OVERTURE is rated faster (300 vs 200 mm/s) and feeds reliably in our AMS; SUNLU is a good choice when stringing is your main problem.
For prototypes and batches, yes, if the spool is dried, vacuum-sealed and holds a tight tolerance. Check the listing for ±0.02–0.03 mm and sealed packaging rather than going by brand alone.
A little. It bends before it breaks, unlike PLA, but it’s a rigid plastic. For truly flexible parts, use TPU.
Yes, if the spool has been open more than a couple of weeks or it starts stringing and popping.
Only certified food-grade PETG, printed with a stainless-steel nozzle and handled with care. Regular PETG spools aren’t certified.
