Polyethylene terephthalate glycol-modified, or PETG 3D printer filament, is a robust, temperature-resistant, and extremely impact-resistant material that is frequently used in 3D printing techniques based on FDM. Here, we'll walk you through using PETG to print properly and assist you in troubleshooting typical problems. While printing with PETG is undoubtedly easier than with materials like ABS. With a little effort, PETG 3D printer filament can produce prints that are exceptionally high-strength and high-quality. Let's get started!
1. Get retraction right
PETG has a strong propensity to ooze and string. Additionally, due to the material's resistance to breaking, molten plastic strings form ugly webs and wisps on your prints. By properly configuring your print settings, as previously mentioned, you can reduce them. Try to increase the travel speed, retraction speed, and retraction distance while staying within safe limits.
2. Prevent cracking
If you're switching from PLA to PETG, you could discover that PETG fractures quite quickly. While PETG can suffer from rapid cooling, PLA benefits from prolonged cooling. Reduce the fan speed if print layers start to separate or fracture. Overhangs and intricate shapes will still be produced with sharp edges since PETG maintains its shape at significantly higher temperatures than PLA. Extruded plastic will have more time to fully adhere to the rest of the sculpture due to the slower cooling.
3. Give support structures space.
Some models printed on PETG 3D printer filament may need support structures, much like those produced on any other FDM material. PETG can, however, attach too firmly to itself once it has been calibrated for layer adhesion, making supports challenging to remove. You could wish to explore the more complex options of your slicing software and widen the gap between the support structures and your actual model.
4. Keep it dry
You could start to notice declining print quality and strength after printing PETG for a long. This is due to PETG's hygroscopic qualities, which allow it to readily absorb moisture from the environment. As a result, make sure to store your filament in a dry location. This should keep the filament from absorbing too much moisture and retain it. You can use an oven heated to about 60 °C to dry off your filament if it is already damp. As the moisture is baked off, keep the spool in the oven for a few hours.
