Common Mistakes to Avoid with PETG Filament

To ensure successful prints with PETG filament, it is crucial to avoid the following common mistakes:

• Over-Extrusion: Excess extrusion can lead to stringing and poor surface finish. Calibrate the filament flow rate and extrusion settings appropriately.
• Under-Extrusion: Insufficient extrusion can result in weak and porous prints. Ensure proper nozzle temperature and filament feed rate.
• Poor Bed Adhesion: Insufficient bed preparation and calibration can cause prints to detach from the build platform. Use a clean build surface and apply an adhesive if necessary.
• Warping: PETG has a tendency to warp due to its semi-crystalline nature. Use a heated bed and ensure proper ventilation to minimize warping.
• Incorrect Printing Temperature: Printing PETG at excessively high or low temperatures can affect its properties and cause printing issues. Refer to the manufacturer's specifications for optimal printing temperatures.

A Step-by-Step Guide to Printing with PETG Filament

1. Prepare the Build Platform: Clean the build platform with isopropyl alcohol and apply an adhesive, such as hairspray or glue stick, to enhance bed adhesion.
2. Set Up the Printer: Calibrate the printer settings according to the filament specifications, including nozzle temperature, bed temperature, and extrusion settings.
3. Load the Filament: Insert the PETG filament into the extruder and ensure it feeds smoothly.
4. Print the Model: Slice the 3D model and generate the G-code for the print. Start the printing process.
5. Monitor the Print: Keep an eye on the printing process to ensure proper adhesion, extrusion, and layer formation.
6. Remove the Print: Once the print is complete, allow it to cool slightly before removing it from the build platform.
