3D printing in PETG
PETG is easy to print and has good mechanical strength and chemical resistance. It resists moisture and handles higher temperatures than PLA. We recommend it for functional parts, holders, mounts and containers.

What is PETG?
PETG is a relative of the plastic used in PET bottles, modified with glycol so it prints better. It's stronger and more impact-resistant than PLA, isn't bothered by water or many chemicals and handles up to about 70 °C. It's the most common choice for parts that have to work, not just look good.

Printing it yourself? PETG settings
Typical ranges from filament manufacturers' data sheets – always check the label on your spool and start with a test print.
- Nozzle temperature
- 230–250 °C
- Bed temperature
- 70–85 °C
- Part cooling
- 30–60%
- Printer enclosure
- not needed
- Drying the filament
- 65 °C for 4–6 h
- On a smooth PEI plate use a glue stick as a release layer – PETG can stick so well it tears out a piece of the surface.
- Stringing usually means damp filament – dry it before you start changing retraction.
No printer, or no time for test prints? We'll print it in PETG.

How much does 3D printing in PETG cost?
For example, a case 90 × 60 × 35 mm in PETG costs PLN 22.15 with us (0.2 mm layers, 20% infill). The price of your model depends on its size, infill and quantity – you'll see it as soon as you upload the file.
Is PETG waterproof?
The material doesn't absorb water and isn't affected by it. Whether a print is watertight depends on the settings: thicker walls and more perimeters give containers that don't leak.
What temperature can PETG handle?
Up to about 70 °C – more than PLA but less than ABS and ASA. The inside of a car in summer can get hotter.
PETG or ASA for outdoors?
Both will cope for a short time. For years in full sun choose ASA – it's UV-resistant and keeps its colour and strength.
Safety: PETG handles temperatures up to about 70°C. Prints are not toys and not for use with food. More about product safety (in Polish)
