PETG Filament

Polyethylene Terephthalate Glycol-modified

A
Also known as:Polyethylene Terephthalate Glycol-modified
Family:PETG

Why Use PETG?

  • Tougher than PLA, higher temp tolerance, more durable in real-world use
  • Good clarity and low friction among easy-to-print materials

Things to Consider

  • Overhangs/bridges sag; supports can be hard to remove
  • Absorbs water fairly quickly

PETG Variants

PETG-CF / PETG-GF

Benefits:

  • + Stiffer, more dimensionally stable, reduced warp

Caveats:

  • - Abrasive; can be more brittle; requires hardened nozzle; often likes a larger nozzle (0.6mm)

Transparent/Clear PETG

Benefits:

  • + Light transmission, lenses, covers

Caveats:

  • - True optical clarity is hard; requires slow printing, thick walls, careful temp and minimal moisture

Frequently Asked Questions

What is PETG filament?
PETG (Polyethylene Terephthalate Glycol-modified) is a 3D printing filament. Tougher than PLA, higher temp tolerance, more durable in real-world use
What temperature should I print PETG at?
PETG typically prints at nozzle temperatures of 215-270°C and bed temperatures of 70-90°C. Moderate cooling; too much cooling can hurt layer adhesion
Do I need an enclosure to print PETG?
An enclosure is optional for printing PETG.
What is PETG filament best for?
PETG is best for: Tougher than PLA, higher temp tolerance, more durable in real-world use; Good clarity and low friction among easy-to-print materials.
What are the downsides of PETG filament?
The main considerations when using PETG: Overhangs/bridges sag; supports can be hard to remove; Absorbs water fairly quickly.
