eSUN PETG
Manufactured by eSUN
Quick Summary
This eSUN PETG review covers one of the most popular budget PETGs for a reason: it is strong, water- and chemical-resistant, tougher than ABS, and it prints without an enclosure or fumes. Dial in retraction and dry the spool, and it is a dependable functional filament for very little money.
Print Settings
eSUN lists 230–250 °C nozzle and a 60–80 °C bed. The single biggest tip is speed: print slower than PLA, around 50–60 mm/s, and make sure the nozzle has room to lay the bead down cleanly rather than brushing the previous layer. Keep cooling modest to protect layer strength.
Print Quality
Layer adhesion and bed adhesion are both strong, giving tough, slightly flexible parts with a smooth, semi-translucent surface. It handles higher service temperatures than PLA and shrugs off chemicals and moisture in use. The main calibration target is clearance and retraction to control stringing.
Where It Falls Short
Like all PETG it is hygroscopic, so an open, damp spool strings until dried. Strong bed adhesion on smooth sheets can pull chips if you do not use a release agent. It is also not as dimensionally precise as premium PETG.
Verdict
For everyday functional parts where you want PETG toughness on a budget, eSUN PETG is hard to fault. Step up to a premium PETG only when tolerance or repeatability is critical.
- eSUN PETG vs overture petg — Both are excellent budget PETG; eSUN runs a touch cooler and cleaner out of the box, while Overture is widely stocked and equally durable.
- eSUN PETG vs prusament petg — Prusament is more dimensionally consistent and easier to dial in; eSUN delivers most of the strength for a fraction of the price.
What temperature should I print eSUN PETG at?
eSUN recommends 230–250 °C at the nozzle with a 60–80 °C bed. Print slower than PLA — around 50–60 mm/s — and give the nozzle room so it does not drag through the previous layer.
Do I need an enclosure for eSUN PETG?
No. PETG prints fine on an open printer with no chamber, does not warp or crack like ABS, and produces no strong odor. A heated bed and a clean first layer are all you really need.
Why is my eSUN PETG stringing?
Usually moisture or too much heat. Dry the spool, drop the nozzle 5–10 °C, and increase retraction slightly. PETG absorbs water faster than PLA, so storage matters.
