PETG Standard

SPECIFICATION

• Material: High-quality PET-G
• Surface: Particularly smooth and glossy appearance
• Diameter: 1.75 mm ± 0.05 mm
• Roundness: ± 3%
• Density: 1.27 g/cm³
• Heat resistance: approx. 70-80°C

PROCESSING INSTRUCTIONS

• Printing temperature: 230–250°C
• Print speed: 40–200 mm/s
• Heated bed temperature: 70–80°C
• Fan speed: 30–100% depending on the geometry of the printed object.
• Suitable for direct drive and Bowden extruders
• Printing speed 30-110mm/s depending on nozzle temperature and layer thickness

The first layer should be 0.3mm thick to compensate for unevenness in the print bed. Large parts should be printed with a heated print bed.
Setting the blower fan to 60% after the first layer helps cool the melt quickly enough, especially on overhangs. If particularly high mechanical strength is required, the blower fan should be switched off or run at only 25% power. Excessive cooling of PET-G reduces its mechanical strength. Bavafil PET-G is suitable for direct drive and Bowden extruders.

1. General Security Information

• For trained personnel only: 3D printing with PET-G filament requires knowledge of printer settings and material behavior. Children may only operate the 3D printer under adult supervision.
• Use only in well-ventilated rooms: Fumes can be produced when printing with PET-G. Therefore, adequate ventilation (ideally active extraction or filters) is required to ensure air quality.

2. Instructions for handling PET-G filament

• Store in a cool, dry placePET-G is sensitive to moisture. Store the filament in an airtight container and, if necessary, with a desiccant.
• Protect from UV radiationSunlight can cause the material to age prematurely and become brittle.
• Safe handling during printingDo not touch hot components (e.g. nozzle, heated bed) and avoid contact with moving parts during operation.

3. Special safety instructions

• Child and pet protection:Keep children and animals away from the printing area. Filament remnants or loose parts can be swallowed or pose a risk of injury.

First aid in case of incidents:

• Burns: Immediately cool skin with cold water after contact with hot printer parts or molten filament; seek medical help if necessary.
• fumesIf you experience discomfort or irritation from fumes: leave the room immediately, go outside to fresh air, and seek medical advice if symptoms persist.

4. User responsibility

• Careful handling requiredThe user is responsible for proper handling and safe operation.
• Suitable protective clothing recommendedWhen removing prints or performing maintenance work, heat-resistant gloves and, if necessary, safety glasses are recommended.
