PETG 3D Printer Filaments

1. Key Properties

Durability: Strong and impact-resistant, making it suitable for functional parts.

Flexibility: Less brittle than PLA, offering moderate flexibility.

Chemical Resistance: Resistant to water, acids, and alkalis.

Transparency: Available in transparent options, ideal for aesthetic applications.

Low Odor: Emits very little odor during printing.

2. Printing Properties

Nozzle Temperature:

Range: 220°C to 250°C

Optimal: Typically 230°C to 245°C depending on the brand.

Bed Temperature:

Range: 70°C to 90°C

Optimal: Around 80°C works for most PETG filaments.

Adhesion:

Strong adhesion to the build plate; may bond too tightly to glass if not handled carefully. Use a layer of glue stick or painter’s tape as a release barrier.

Speed: Slightly slower than PLA; typically 40–60 mm/s for optimal quality.

Cooling:

Minimal part cooling is recommended (20%-50%) to avoid weak layer bonding.
