PETG 3D Printer Filament Tips, Tricks and Uses!

PETG is best known as the polymer used in water bottles, it is also found in clothing fibres and food containers. ‘G’ in PETG stands for “glycol-modified”, this makes the filament more clearer, less brittle, and most importantly it is easier to use. This is often considered a good middle ground between ABS and PLA, as it is more flexible and durable than PLA and easier to print than ABS.

When using PETG:

  • Make sure to store the 3D printer filament in a cool, dry place. “Why you ask?”, because it is hygroscopic, meaning it will absorbs moisture from the air, this will have a negative effect on printing.
  • This filament will become sticky during printing, making this a poor choice for support structures, but it’s good for layer adhesion. (Just be careful with the print bed!)
  • It will also scratch more easily than ABS.
  • Since this material is hygroscopic, consider either purchasing or making a filament dryer

3D Printer Filament Properties:

  • Strength: High | Flexibility: Medium | Durability: High
  • Difficulty to use: Low
  • Print temperature: 220°C – 250°C
  • Print bed temperature: 50°C – 75°C
  • Shrinkage/warping: Minimal
  • Soluble: No
  • Food safety: Refer to manufacturer guidelines

When should I use It?

PETG is a good all-rounder due to its flexibility, strength, and temperature and impact resistance. This makes it an ideal 3D printer filament to use for objects, that can handle sustained or sudden stress, like mechanical parts, printer parts, and protective components.
